Solidity 0.8.37 release notes disclosing three EF bug-bounty-reported compiler bugs with security implications: deleting an element of a memory bytes array (or converted string) zeroed the full 32-byte word instead of one byte, corrupting adjacent data in the evmasm pipeline (all versions ≤0.8.36); a stack-to-memory spill-slot collision in mutually recursive functions under --via-ir silently overwrote live variables (0.7.2–0.8.36); and require() with a custom error using named arguments encoded parameters in call-site rather than declaration order, producing structurally valid but semantically wrong revert data. The release also adds two non-security miscompilation fixes, an experimental planning-based stack shuffler for the SSA CFG backend, support for the Amsterdam EVM's SLOTNUM opcode (EIP-7843), and removes/deprecates several experimental features.

The Solidity team discloses a bug (reported by Cantina Security via the Ethereum Foundation bug bounty) where the IR-based (--via-ir) code generator pushed named custom-error arguments in call-site order instead of declaration order before ABI-encoding, corrupting revert data for require(condition, ErrorName({...})) calls with reordered named parameters. Introduced in Solidity 0.8.26 and fixed in 0.8.37, the bug produces silently swapped or type-confused values in decoded revert data with no compiler warning, and can cause misaligned encoding in multi-slot-argument cases that either reverts with undecodable data or produces a plausible-but-wrong payload - a real concern for standards like ERC-3668 (CCIP Read) that treat revert data as part of the contract interface. Severity was rated "very low" since the affected transaction is already reverting and there is no attacker-controlled exploitation path, but audits of via-ir contracts using named custom-error arguments should check for it.

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.

Attackers craft a template expression using the valueOf filter (1|valueOf) to escape the sandbox, chain prototype manipulation to reach internal engine objects (parser, loader, filters), and ultimately invoke the JavaScript Function constructor for arbitrary command execution; a public PoC demonstrates file reads and execSync-based RCE, and CCB Belgium's national CERT has issued an advisory urging immediate patching.

CVE-2026-45829 (CVSS 10.0) is a pre-authentication remote code execution flaw in ChromaDB's Python FastAPI server, versions 1.0.0 through 1.5.8. The server processes user-controlled embedding function configuration before authentication checks, letting an attacker send a crafted collection-creation request referencing a malicious HuggingFace model with trust_remote_code enabled to force arbitrary Python code execution pre-auth. Discovered by researcher Azraelxuemo and later HiddenLayer (dubbed "ChromaToast Served Pre-Auth"); Shodan-based scanning found roughly 73% of internet-exposed ChromaDB instances still vulnerable, with fixes shipped in 1.5.9.

Orca Security breaks down CVE-2026-9082, a critical unauthenticated SQL injection in Drupal core's database abstraction API affecting PostgreSQL-backed sites running versions 8.9.0 through 11.3.9. The flaw stems from insufficient query sanitization and can lead to full data exposure, privilege escalation, and in some configurations remote code execution; Drupal has shipped patched releases (e.g. 11.3.10, 10.6.9) and MySQL/MariaDB sites are unaffected by the SQLi itself but should still update for bundled Symfony/Twig fixes.

Joint guidance co-authored by ASD's ACSC, CISA, NSA, the Canadian Centre for Cyber Security, NCSC-NZ and NCSC-UK on securing LLM-based agentic AI systems across critical infrastructure and defence. It catalogs agentic-AI-specific risk categories — privilege compromise, scope creep, confused-deputy attacks, identity spoofing, insecure static permission checks, indirect prompt injection, specification gaming and deceptive/emergent agent behaviour — with concrete scenario examples, and lays out best practices for designing, developing, deploying and operating agents securely.

A joint guidance document from ASD's ACSC, US CISA/NSA, the Canadian Centre for Cyber Security, NCSC-NZ and NCSC-UK on securely adopting LLM-based agentic AI systems. It details agentic-specific risk categories — privilege compromise and scope creep, identity spoofing/agent impersonation, confused-deputy attacks, insecure static permission checks, goal misalignment/specification gaming, and deceptive or emergent agent behaviour — with concrete scenarios (a procurement agent with excessive privileges, a support-triage agent with a compromised third-party scheduling component, an update agent tricked into deleting firewall logs). It closes with lifecycle best practices for designing, developing, deploying and operating agents securely, plus recommendations on threat-intel sharing and agent-specific evaluations.

Wiz's analysis of CVE-2026-31431 ("Copy Fail"), a logic flaw in the Linux kernel's AEAD crypto implementation (algif_aead) that, when chained with AF_ALG sockets and splice(), lets an unprivileged local user write 4 controlled bytes into the page cache of any readable file — including setuid binaries like /usr/bin/su — to gain root. It affects nearly all kernels built since 2017, also enables container escape between co-located containers sharing a base image, and the post covers patch status, seccomp-based mitigation, and detection heuristics (delayed AF_ALG loading, malformed su auth.log entries).

Ubuntu Security Team advisory for CVE-2026-31431 ("Copy Fail"), a HIGH severity (CVSS 7.8) local privilege escalation vulnerability in the Linux kernel's algif_aead cryptographic acceleration module, affecting all Ubuntu releases before 26.04 (Resolute). A public exploit lets a local user escalate to root on non-containerized hosts, while container deployments may face escape scenarios (no PoC yet for that path); the advisory covers the temporary kmod-based module-disabling mitigation, the permanent kernel patch, and manual remediation steps via modprobe.d.

Analysis of CVE-2025-62878 (CVSS 10.0), a path traversal flaw in Rancher's Local Path Provisioner — the default StorageClass backend for K3s — caused by unsanitized pathPattern templates in StorageClass definitions being joined into filesystem paths via filepath.Join. Exploitation lets an attacker escape the configured base storage directory to read/write/delete arbitrary host files (e.g. /etc/kubernetes/pki, /root/.ssh/authorized_keys) through a helper pod that gains host access via a hostPath mount rather than privileged mode, evading policies that only block privileged containers. The piece also challenges the CVSS 10.0 rating given the cluster-admin RBAC typically required, and covers a post-patch bypass via the allowUnsafePathPattern escape hatch.

CVE-2026-25536 is a cross-client data leak in the official MCP TypeScript SDK (v1.10.0-1.25.3, CVSS 7.1): when a single McpServer instance reuses a StreamableHTTPServerTransport across multiple concurrent client connections, a race condition in the response multiplexing logic can route one client's tool results, resource content, or errors to a different client. This breaks tenant isolation in multi-user MCP server deployments, a common production pattern, potentially exposing sensitive API responses, file contents, or database query results across security boundaries. Fixed in SDK v1.26.0; recommended mitigations include upgrading, using per-client McpServer instances, and adding client-side response correlation checks.

CVE-2026-21852 describes a flaw in Claude Code versions prior to 2.0.65 where a malicious repository's settings file can override ANTHROPIC_BASE_URL and have it applied during project load before the user sees or accepts the trust-confirmation prompt, causing the user's Anthropic API key to be sent to an attacker-controlled endpoint. The root cause is an initialization-order bug (CWE-522, insufficiently protected credentials) where untrusted repo config is parsed and acted on ahead of trust verification; Anthropic fixed it in 2.0.65 by moving trust checks before config processing. Mitigations include updating, rotating exposed keys, and avoiding opening unfamiliar repos until patched.
