CVE-2025-34291 (CVSS 9.4) enables arbitrary code execution via origin validation and chained weaknesses, exposing stored tokens and API keys. CVE-2026-34926 (CVSS 6.7) is a directory traversal affecting on-premise Apex One, requiring server access and admin credentials to exploit. Federal agencies must patch by June 4, 2026.

🔒 Cisco issued updates for a maximum-severity vulnerability (CVE-2026-20223) in Secure Workload that allows unauthenticated, remote access to REST API endpoints. The flaw permits crafted API requests to read sensitive data and change configurations across tenant boundaries with Site Admin privileges. Affected versions include Release 3.9 and earlier (migrate), 3.10 (fixed in 3.10.8.3), and 4.0 (fixed in 4.0.3.17). Cisco discovered the issue internally and reports no evidence of exploitation in the wild.

🔒 A critical vulnerability in the on-premises Cisco Secure Workload platform can let a remote, unauthenticated attacker gain site admin privileges by sending a crafted HTTP request to an internal REST API. Cisco assigned CVE-2026-20223 a CVSS score of 10.0 and says the issue stems from insufficient validation and authentication of REST API access. Only on-prem deployments must act immediately by upgrading to the patched versions; SaaS has already been fixed. Cisco reported no known exploitation in the wild at the time of disclosure.

🔒 Microsoft released emergency fixes addressing two zero-day vulnerabilities in the malware protection components of Microsoft Defender. The flaws let local attackers escalate to system-level privileges or disrupt the anti-malware service, both of which aid malware persistence and control. CISA added CVE-2026-41091 and CVE-2026-45498 to its KEV catalog after in-the-wild exploitation was detected, and administrators are urged to update the Malware Protection Engine and Antimalware Platform to the specified versions immediately.

🔒 Researchers disclosed a critical vulnerability in ChromaDB (CVE-2026-45829) that allows unauthenticated attackers to execute arbitrary code and access sensitive data on affected servers. The flaw is a race condition in the FastAPI-based API server that fetches and executes remote embedding model code before performing authentication checks. HiddenLayer says versions 1.0.0 through 1.5.8 are affected and many public instances remain vulnerable; they recommend using the Rust implementation and restricting network access until a patch is available.

🛡️ Google inadvertently published details of an unfixed Chromium vulnerability that allows JavaScript to continue running after the browser is closed, enabling remote code execution via persistent Service Workers. Reported by researcher Lyra Rebane in December 2022, the issue affects all Chromium-based browsers and was marked fixed in February 2024 but a patch was not shipped. The bug tracker entry was briefly made public on May 20, revealing the exploit still works in Chrome Dev 150 and Edge 148, making attacks stealthier and increasing risk until an emergency fix is released.
