⚠️ A max-severity flaw (CVE-2026-45829) in the Python FastAPI server of ChromaDB allows unauthenticated attackers to load and execute remote models before authentication is enforced, enabling arbitrary code execution on exposed servers. The issue impacts PyPI-distributed releases used widely in AI retrieval stacks; a 1.5.9 release exists but it is unclear if the fix addresses this vulnerability. Mitigations include using the Rust frontend, avoiding public exposure of the Python API, and restricting network access to the ChromaDB API port.

📈 Digital.ai's 2026 Application Security Threat Report found that 87% of monitored customer-facing apps were attacked in 2026, up sharply from 55% in 2022. The firm says agentic AI has lowered the skill and time required for threat actors to inspect code, generate exploits and adapt malware. Financial services, automotive and medical device apps were most targeted, and iOS attacks have nearly closed the gap with Android.

🔒 Security researchers from StepSecurity report that the popular GitHub Actions workflow actions-cool/issues-helper was hijacked by attackers who moved existing tags to imposter commits in an adversary-controlled fork. The malicious commit downloads the Bun JavaScript runtime, reads memory from the Runner.Worker process to harvest CI/CD credentials, and exfiltrates them to an attacker-controlled domain. A second action, actions-cool/maintain-one-comment, had 15 tags similarly altered. GitHub has disabled repository access and only workflows pinned to full commit SHAs remain unaffected.

⚠️A new zero-day called YellowKey, published this week by a researcher using the alias Nightmare-Eclipse, demonstrates a reliable bypass of default Windows 11 BitLocker deployments. The exploit circumvents disk encryption that relies solely on the TPM-stored key and requires physical access to the affected machine. Organizations that mandate BitLocker, including government contractors, should reassess device physical security and BitLocker configuration.
