CVE-2026-98432 is a Linux kernel use-after-free in the IPv4 TCP stack, tracked by Ubuntu (published 15 October 2026, updated 29 October 2026). ireq_opt/inet_opt were freed with plain kfree() while another CPU built a SYNACK under RCU, so ip_options_build() read freed memory; the fix uses kfree_rcu(). Ubuntu rates it High priority, CVSS v3.1 9.8 and v4.0 8.3. The page text does not list per-release package status.

The visit_page tool only validates URL protocol and does not filter private, loopback, link-local, or cloud metadata IP ranges, so an attacker who controls the LLM-supplied URL argument (e.g. via prompt injection) can steer the server's Playwright browser to internal endpoints like cloud instance metadata services and exfiltrate sensitive internal content, including credentials, back into the model context.

CVE-2026-42271 describes an unauthenticated-privilege RCE in LiteLLM (versions 1.74.2 to before 1.83.7): the MCP server preview endpoints POST /mcp-rest/test/connection and POST /mcp-rest/test/tools/list accept a full stdio MCP server config (command, args, env) and spawn it as a subprocess on the proxy host, gated only by a valid API key with no role check. Any authenticated user, including low-privilege internal-user keys, could run arbitrary commands on the LiteLLM proxy host. Patched in v1.83.7; also tracked as GHSA-v4p8-mg3p-g94g and affects Red Hat OpenShift AI.

CVE-2026-18655 describes an improper endpoint restriction flaw (CWE-923) in the RabbitMQ broker connection tools of awslabs.amazon-mq-mcp-server versions before 2.0.24. A remote unauthenticated attacker can use prompt injection introduced into the MCP client context to redirect the broker hostname to an attacker-controlled endpoint, causing Amazon MQ for RabbitMQ credentials or OAuth access tokens to be sent there; CVSS 4.0 base score 7.1 (High).

CVE-2026-16584 affects AWS API MCP Server (awslabs.aws-api-mcp-server) versions 0.2.13 through 1.3.46: if the security policy enforcement data fails to initialize at server startup, the tool silently skips policy checks for the rest of the process's life, letting an agent execute AWS API operations the admin configured the policy to deny or gate. Underlying IAM permissions still apply and are unaffected, but the intended allow/deny gating layer is bypassed (CWE-455, improper handling of initialization failure). Fixed in 1.3.47.

When the Publish server runs in anonymous mode (a documented configuration for public docs sites), the Publish reverse proxy attaches an anonymous RoleReader JWT to every proxied request, letting an unauthenticated attacker reach /mcp, exfiltrate accessAuthCode/api.token/cookieKey from conf.json, escalate to Administrator, and plant a malicious Electron plugin (nodeIntegration:true, contextIsolation:false) for RCE on the desktop client.

n8n's AI Agents module did not enforce the "Allowed HTTP Request Domains" restriction on credentials. A member-level user with use-only access to a shared credential could point an MCP tool at an attacker-controlled URL and run the agent, so the credential secret was sent to an external server. It only affects instances with the agents module enabled via N8N_ENABLED_MODULES and a domain-restricted credential shared with a member.

A GitHub Security Advisory (GHSA-5p9g-j988-pcwv) documents a session poisoning flaw in the Ruby MCP SDK's Streamable/SSE HTTP transport: the server never validates that a POST to /messages/{session_id} actually belongs to the caller, so an attacker who obtains a victim's session ID (e.g. via logs or network sniffing) can silently execute tool calls whose responses are delivered into the victim's own SSE stream. The advisory includes a working PoC (attacker/legitimate client scripts against the SDK's example streamable_http_server.rb), notes that csharp-sdk and go-sdk correctly bind sessions to user identity while ruby-sdk does not, and distinguishes the bug from the related "Stream Replacement" advisory (GHSA-qvqr-5cv7-wh35), which disconnects rather than poisons the victim's stream.

GHSA-9hgc-g3w5-67cm details a DNS TOCTOU race in IBM mcp-context-forge's /admin/gateways/test endpoint: validate_gateway_test_url() resolves and vets a hostname against private/cloud-metadata IP ranges, but the actual request is made with httpx (via ResilientHttpClient), which independently re-resolves DNS at connection time with no IP pinning. An attacker with gateways.read permission can exploit DNS rebinding (short-TTL record flipping from a public IP to 169.254.169.254) to bypass SSRF protections and reach cloud instance metadata, exfiltrating IAM credentials where IMDSv1 is enabled.

CVE-2026-81735 is a CVSS 10 unauthenticated RCE in the mcp-http-server package used by UI-TARS-desktop.

The Solidity team discloses a medium-severity compiler bug present from Solidity 0.8.29 through 0.8.35 (fixed in 0.8.36): the code that emits Warning 3495 (custom storage layout too close to storage end) uses ranges-v3's actions::reverse instead of views::reverse, permanently mutating the linearizedBaseContracts AST annotation instead of only reading a reversed copy. Because that annotation drives inheritance-order decisions throughout analysis and codegen, affected contracts can get reversed constructor execution order, wrong super/virtual-function and virtual-modifier resolution, and incorrect fallback/receive dispatch — either silently miscompiling or triggering internal compiler errors. Exploitation requires a contract using both inheritance and a `layout at` clause landing within the last 2^64 storage slots, a pattern the team found no real-world evidence of via GitHub and Sourcify scans.

Because Langflow ships with unauthenticated auto-login enabled by default, a single unauthenticated request is enough to obtain a session and exploit it, escalating to RCE via cron job injection or config overwrite. Tenable disclosed it after failed vendor contact, VulnCheck has confirmed active exploitation against roughly 7,000 internet-exposed instances, and a public PoC exists; fixed in Langflow 1.9.0/1.10.0 and langflow-base 0.8.3.

Orca Security details CVE-2026-45034 (CVSS 9.8), a bypass of PhpSpreadsheet's File::prohibitWrappers() protection that was originally added to fix CVE-2026-34084. A crafted path with three or more slashes after the scheme (e.g. phar:///path/exploit.phar/dummy.csv) causes PHP's parse_url() to return false instead of a scheme string, skipping the is_string($scheme) check while PHP's stream layer still treats the path as a phar wrapper, enabling automatic phar deserialization via IOFactory::load() and full RCE on PHP 7.x (file-read primitive on PHP 8.x, with RCE restored if Phar::getMetadata() is later called). All 1.x versions through 1.30.4 are affected; PhpSpreadsheet 1.30.5 patches the issue, and the post recommends replacing parse_url()-based checks with str_contains($filename, '://') validation.

Aikido Security discovered an unauthenticated authentication bypass in phpBB (versions up to 3.3.16 and 4.0.0-a2) that lets an attacker forge a valid session for any user via a single HTTP request, since the member list is public by default. Admin account takeover exposes full read/write/delete access, though a separate ACP password check blocks direct RCE. Fixed in phpBB 3.3.17, disclosed via HackerOne with a 4-day patch turnaround; technical exploit details withheld pending upgrade adoption.

Orca Security details CVE-2026-8206 (CVSS 9.8), a critical unauthenticated account-takeover flaw in the Kirki Freeform Page Builder, Website Builder and Customizer WordPress plugin versions 6.0.0-6.0.6. The bug lives in handle_forgot_password() of the CompLibFormHandler class, whose custom REST endpoint accepts an attacker-supplied email instead of the account registered address, letting an attacker redirect the password-reset link and seize admin accounts. Active exploitation is already confirmed (Wordfence logged 59 blocked attacks in 24 hours), and roughly 150,000 of 500,000+ installs remain unpatched pending the 6.0.7 fix.

Orca Security breaks down CVE-2026-45695 (CVSS 9.8), an unauthenticated RCE in the Kopia backup tool's HTTP server, affecting versions 0.22.3 and earlier. The flaw stems from Kopia's /api/v1/repo/exists endpoint splitting SFTP storage configuration fields on literal spaces without a proper tokenizer or quote handling, letting an attacker inject `-oProxyCommand=<cmd>` into the SSH command line when the server runs with --without-password and SFTP/external-SSH enabled — achieving code execution via a single crafted HTTP request. Fix is Kopia 0.23.0, which blocks starting with --insecure/--without-password on non-loopback interfaces; researcher Daniele Berardinelli reported it, tracked as GHSA-2q4c-3mrw-63c3.
