A security advisory (CVE-2026-40217) disclosed a sandbox escape vulnerability in LiteLLM's custom-code guardrail feature (OSV advisory). This could allow an attacker to escape the sandbox and gain unauthorized access, potentially affecting users relying on that feature. Subsequent PyPI releases (e.g., 1.84.2, 1.86.1, 1.88.0rc1) between May 26-31 suggest active development and likely a fix, but no explicit confirmation is found in the sources. The single source and lack of immediate impact reports lower confidence.
