[CVE-2026-59822]

September 11, 2026

• Wiz scanned ~3,000 internet-facing LiteLLM gateways and found 9.6% accepted the documented example master key sk-1234 or required no auth at all — which turns a post-auth root RCE via custom code guardrails (CVE-2026-59821) into an effectively pre-auth one. An MCP endpoint auth bypass (CVE-2026-59822) lets any Bearer token mint a valid session, was confirmed exploitable on hundreds of instances, was added to CISA KEV on 2 September, and Wiz saw it exploited in the wild on its honeypots. A pass-through endpoint with no URL validation enables cloud credential theft and was not assigned a CVE or fixed. Patches exist for the rest; the work was presented at DEF CON 34 (Wiz, The Hacker News). · AI Infrastructure & Agent Security

• CISA added seven actively exploited flaws to KEV, spanning an unusually broad stack: CVE-2026-83548 (SonicWall SMA 1000 pre-auth SSRF, CVSS 10.0), CVE-2026-82329 (JFrog Artifactory auth bypass), CVE-2026-9586 (Sangoma Switchvox pre-auth SQLi), CVE-2026-59822 (BerriAI LiteLLM improper authentication), CVE-2026-48710 (Starlette request smuggling) and CVE-2026-49869 (Kestra OSS command injection) (CISA). Observed post-exploitation is reverse shells and crypto miners (The Hacker News); the Artifactory bug is being used to forge admin tokens (BleepingComputer). LiteLLM sitting in KEV is the signal to watch — AI gateway middleware is now in the exploited-in-the-wild category. · Exploitation & Vulnerabilities
