Inside mobile taint analysis: how source-to-sink tracking finds real data-leak paths | Oversecured Blog

Oversecured explains taint analysis for Android and iOS apps and contrasts it with pattern-matching SAST such as MobSF. It covers source, flow and sink, cross-component tracking over Intents, flag-based sanitizer modeling and implicit intent simulation. The case study is an unsafe Class.forName().newInstance() on a Serializable transportFactoryClassName field in Google's com.google.auth.oauth2 credential classes, which Google fixed with a $3,133.70 bounty.

Vulnerabilities that lead to account takeover in banking and fintech mobile apps | Oversecured Blog

Oversecured guide to eight vulnerability categories that lead to account takeover in mobile banking and fintech apps: WebView JavaScript bridge token leakage, Intent Redirection, hardcoded tokens, deeplink hijacking, insecure token storage, localhost OAuth listeners, AIDL abuse and weak biometric auth. It includes a WebView PoC based on Samsung SmartThings CVE-2022-30746 and maps findings to OWASP MASVS, PCI DSS and PSD2. It argues taint analysis plus dynamic PoC is needed to find multi-component chains.

clauth is a Rust terminal UI for Claude Code that combines multi-account switching with a live 5h / 7d usage monitor. A fallback chain moves the user off an exhausted account before Claude Code blocks. It supports Pro, Max, Team and Enterprise OAuth accounts and custom API endpoints on Linux, macOS and Windows. The post notes that auto-switching means the tool decides when accounts change.

Thread by Kizuno18 on the move from local stdio/Docker Model Context Protocol servers to remote HTTP/SSE endpoints in enterprise infrastructure. It names three trade-offs: credential boundary inversion (short-lived OAuth/JWT tokens instead of long-lived admin tokens on workstations), tool schema bloat solved by deferred discovery, and governance via HCP Terraform policy-as-code (Sentinel/OPA), audit trails and approvals. It is opinion, with no data or implementation detail.

It lists three trade-offs: short-lived OAuth/JWT bearer tokens replace mounted admin credentials, deferred tool discovery avoids roughly 20k tokens of eager schema loading, and HCP Terraform enforces Sentinel/OPA policy, audit trails and approvals server-side.

Thread on a critical opencode bug disclosed by Pillar Security on Oct 19. On Windows and WSL, a remote MCP server could run code during OAuth sign-in, because the server-chosen authorization URL was put unescaped into a PowerShell command, so a PowerShell subexpression executed. opencode fixed it in 1.18.33 on Sep 28 as a browser-launch refactor with no advisory or CVE.

China APT Uses AI Pentest Tool Artex in ConnectWise Attacks

Storm-0940, a China-linked APT, used the open source AI penetration testing framework Artex to automate a mid-October 2026 campaign against ConnectWise customers, per Microsoft. Artex drove reconnaissance, password spraying and OAuth application abuse at more than 2,900 attempts per minute, with sign-in attempts against over 2,250 tenants. Attackers modified application credentials for persistence, and Microsoft advises correlating service principal sign-ins with Graph activity.

LiteLLM Compromised in Fresh Supply Chain Attack

LiteLLM version 1.107.0 was published with malware to PyPI and Docker Hub on October 21, for about three hours and roughly 49,000 downloads. Attackers used GitHub CLI OAuth tokens, likely leaked through Claude Code into LiteLLM logs, to disable branch protections, redirect the releaser to a lookalike repository and sign poisoned artifacts. The payload is an infostealer and RAT; Wiz saw Amazon Bedrock abuse. The last clean version is 1.106.2.

LiteLLM suspects its October 21 release compromise began with Claude Code responses containing GitHub CLI OAuth tokens that were written to logs of an internet-facing internal LiteLLM gateway. Attackers allegedly stole those tokens, used an organization-owner token to disable branch protections, and pushed poisoned artifacts from a lookalike repository. How they entered the gateway is unconfirmed, and this is not a proven Claude Code vulnerability.

The author uses it to argue that delegated agent authority needs provenance (who granted it, to which agent, for which service and resource, whether it is transferable or replayable, and when it expires) and that machine-to-machine trust must be auditable by humans.

Solving the Identity Crisis for AI Agents (Uber)

Uber's engineering team describes how it extended its Zero Trust stack to give AI agents verifiable identities. Each agent workload gets a SPIRE SVID, and a Security Token Service checks an Agent Registry and mints single-hop, short-lived JWTs. Those tokens carry the full actor chain (for example user → Oncall Agent → Investigation Agent), loosely modelled on OAuth 2.0 Token Exchange (RFC 8693). The tokens are enforced at an MCP Gateway for tool calls, and an AI Gateway fronts model calls with guardrails. The post also covers an A2A client in the SDK that makes the secure path the default, observability of actor chains, and a 2026 roadmap toward dynamic access control and unified policy enforcement. It is a concrete production reference for agent attribution and delegated authorization.

Announcement of mcpc v0.7.0, Apify's open-source MCP CLI client (npm i -g @apify/mcpc), which adds support for the MCP Skills extension with new skills-list/skills-get commands that verify SKILL.md and supporting files against the skill manifest via size and SHA-256 checks before printing content. The release also ships security hardening: repo-local .mcp.json auto-discovery can no longer read environment variables (blocking leaks like $GITHUB_TOKEN), OAuth refresh tokens are now scoped only to the auth server originally used, and Windows login URLs no longer launch through cmd.exe.

Folkbench has two parts. One is a public benchmark and leaderboard of third-party AI API relay (中转站) services. Multi-node probes run around the clock and publish availability, P95 latency and price per relay, with per-model rankings. The other is Switch, an open-source Tauri/Rust desktop client that stores several Base URL and API Key pairs. It applies them to Claude Code or Codex configs in one click, previews config diffs, and stashes and restores the official ChatGPT OAuth credentials when switching Codex to a third-party provider. It also keeps keys local and estimates token usage and cost per session. The README also profiles several relay services, such as Modelflare, CheapAI and ApiPorter, and that part reads as promotional.

MCP TypeScript SDK v2.2.0

Release notes for v2.2.0 of the official Model Context Protocol TypeScript SDK. Upgrade notes: machine-to-machine OAuth providers (ClientCredentialsProvider, PrivateKeyJwtProvider, StaticPrivateKeyJwtProvider, CrossAppAccessProvider) should now be given expectedIssuer, and fetchToken() throws AuthorizationServerMismatchError when client information is bound to a different authorization server. listTools/listPrompts/listResources/listResourceTemplates now follow nextCursor automatically, capped by listMaxPages. Fixes include CommonJS type-checking of the DPoP jose types, unhandled rejections in Client.listen(), createMcpHandler stack overflow and subscriptions/listen handling, .localhost loopback for OAuth token endpoints, and v1-to-v2 codemod comment preservation.

Identity Management for Agentic AI [pdf] (2025)

A whitepaper from the OpenID Foundation, led by Tobin South with contributors from WorkOS, Stanford's Loyal Agents Initiative, and the Artificial Intelligence Identity Management Community Group, mapping how authentication and authorization standards apply to AI agents. It surveys current fixes (OAuth 2.1, Model Context Protocol authorization, enterprise SSO/SCIM provisioning, IPSIE profiles) and lays out unsolved problems for autonomous agents: delegated "on-behalf-of" identity versus user impersonation, consent fatigue at scale, recursive sub-agent delegation, multi-user shared agents, and browser/computer-use agents that bypass API-based authorization entirely.

OpenID Foundation whitepaper (Oct 2025, lead editor Tobin South) analyzing how authentication/authorization for AI agents differs from traditional software clients. It covers where OAuth 2.1, OIDC, SSO/SCIM, and MCP already work for single-domain synchronous agents, and lays out unsolved problems for autonomous agentic identity: agent identity fragmentation across vendors, replacing user impersonation with explicit delegated "on-behalf-of" authority, consent-fatigue at scale, recursive delegation chains between sub-agents, agents acting for teams of users, and browser/computer-use agents bypassing API-based authorization entirely.

MCP Python SDK v2.2.0

Release notes for MCP Python SDK v2.2.0 detailing several security-relevant default changes: HTTP clients (Client, streamable_http_client, sse_client) now only follow redirects within the same origin, closing a cross-origin redirect trust gap; OAuth clients now validate the authorization server's issuer even on the legacy (non-protected-resource-metadata) discovery path, preventing metadata/issuer mismatch attacks; idle Streamable HTTP sessions now expire after 30 minutes with a 10,000-session cap to limit resource exhaustion; and a new AuthSettings.validate_token_resource setting lets servers reject bearer tokens not issued for them (audience/resource confusion). Deprecation warnings push OAuth provider configs toward requiring an explicit issuer ahead of a 3.0 breaking change.

CVE-2026-49291: mcp-memory-service is a semantic memory layer for AI applications

CVE-2026-49291 affects mcp-memory-service prior to version 10.65.3: its HTTP MCP JSON-RPC endpoint at /mcp only enforced OAuth 'read' scope before dispatching tools/call requests, so a client holding only read access could invoke mutating tools like store_memory and delete_memory even though the equivalent REST endpoints correctly required 'write' scope. The flaw is a classic missing-authorization bug (CWE-862) surfacing specifically in an MCP tool-dispatch layer, scored CVSS 3.1 8.1 (High) with confidentiality unaffected but integrity and availability impacted. Fixed in 10.65.3.

CVE-2026-14541 describes an authentication bypass (CWE-287) in the Google OAuth provider of Google's mcp-toolbox for databases v1.4.0, an MCP server that lets LLM agents query databases. When the Google authService is configured with mcpEnabled: true but no explicit audience or clientId, the ValidateMCPAuth pipeline skips audience checks for opaque tokens, so any valid Google OAuth access token — even one issued for an unrelated app — is accepted, letting unauthorized clients reach protected tools and data backends.

Insecure cryptographic defaults in oidcProvider: alg=none advertised and plain PKCE accepted by default

GHSA advisory for better-auth (< 1.6.11) documenting that the deprecated oidcProvider() and mcp() plugins publish "none" as a supported ID-token signing algorithm in their OIDC discovery document and default allowPlainCodeChallengeMethod to true, silently rewriting missing code_challenge_method to "plain" — both violating OAuth 2.1/RFC 9700. The fix removes "none" from the metadata, defaults plain PKCE to disabled, and rejects requests missing code_challenge_method instead of downgrading them; @better-auth/oauth-provider was never affected.

A First Measurement Study on Authentication Security in Real-World Remote MCP Servers

The first large-scale measurement study of authentication security across real-world remote MCP servers, scanning 7,973 live deployments and finding 40.55% expose tools with no authentication at all. For the 119 testable OAuth-enabled servers, the authors built a semi-automated (passive traffic inspection + active dynamic probing) detection framework and derived a taxonomy of nine flaw types across four categories — three MCP-specific (open client environments, dynamic client registration, delegated authorization) and conventional OAuth misconfigurations — finding every tested server had at least one flaw, with dynamic client registration flaws hitting 96.6% of servers and leading to information leakage or account takeover; the work resulted in 9 CVEs via responsible disclosure.

Malicious Firefox Extension Poses as PDF Identity Verifier to Hijack Google Accounts

Socket's Threat Research team dissects a malicious Firefox extension (pdf-para-texto@extensao.local, "PDF Identity Verifier") that ships with no hardcoded malicious code — all attack logic is fetched as data into browser.storage.local after install via a lookalike domain (pdf.gusercontent.com), evading static store review. Once armed, it abuses Google's FedCM API to silently identify the victim, injects a live automation script into real accounts.google.com pages to drive an invisible account-takeover flow (bypassing password entry, forcing passkey challenges, dodging Google's bot detection, and forcing/capturing a password reset), while a webRequest listener steals the oauth_token session cookie from Set-Cookie headers — giving the attacker both a live session and a durable new password. The campaign targets Portuguese- and Spanish-speaking users starting September 2026 and includes full IOCs (domains, file hashes) and remediation steps.

OAuth Token Theft Through Microsoft's Front Door | Huntress

Huntress researcher Andrew Schwartz demonstrates a novel OAuth token-theft technique: a sideloaded AppX package registered via Add-AppxPackage -Register (requiring only Developer Mode, no admin beyond that toggle) can set ContentUriRules WindowsRuntimeAccess="all" so attacker-controlled JavaScript rendered inside the Microsoft-signed WWAHost.exe process gets full WinRT access, including the legacy WebAuthenticationBroker OAuth API. Using Microsoft Office's own client ID and the oob redirect URI, the attacker triggers a genuine login.microsoftonline.com/MFA dialog with no browser chrome, captures the auth code, and exchanges it for an access token plus a long-lived refresh token carrying the full Office delegated Graph scope set (mail, files, Teams, directory, AuditLog.Create) — validated end-to-end against a live Entra ID tenant with MFA and default Conditional Access. The post frames it as a class of vulnerable signed AppX host binaries sharing the same WinRT activation layer, and provides a Sigma rule keyed on the MSAppHost/3.0 EdgeHTML user agent reaching non-Microsoft destinations, plus Sysmon/Event ID and GPO-based mitigations (restricting Developer Mode, Conditional Access, shorter refresh-token lifetimes, CAE).

Static Defenses vs. Dynamic Exploits: Why A2AS Fails at the Runtime

Tenet Threat Labs red-teamed a GPT-4o agent with all five A2AS BASIC pillars enabled and an MCP server. A tool response disguised as HTTP 206 pagination and OAuth steps ("Tool Parameter Injection via Semantic Orchestration Mimicry") led the agent to run a shell script, read credentials.txt and exfiltrate the token. It succeeded in over 80% of runs in November 2025. The authors argue for runtime enforcement based on content trust levels.
