On 2026-05-11, a security advisory (GHSA-wxxx-gvqv-xp7p) disclosed CVE-2026-40217 affecting LiteLLM, a popular open-source AI gateway. The vulnerability enables a sandbox escape in custom-code guardrails, potentially allowing attackers to execute arbitrary code. This represents a significant security risk for organizations using LiteLLM's guardrail feature to enforce LLM safety. The advisory is published on OSV.dev and references the CVE. While LiteLLM has continued frequent PyPI releases (up to v1.88.0rc1 by early June), no patch has been confirmed yet for this specific issue. Users running custom guardrails should assess exposure and apply mitigations as needed. Source: OSV advisory.
