Summary

CVE-2026-12772 is a low-severity Insufficient Session Expiration (CWE-613) vulnerability in Litellm Litellm. Its CVSS base score is 2.1 (Low).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 18th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to AC-12 (Session Termination) and IA-11 (Re-authentication) — see the control section below for these in your framework.

Mitigating Controls (NIST 800-53 r5) AI

AC-12 Session Termination good match
prevent

Directly enforces session termination/expiration to address CWE-613 insufficient session expiration in the authenticate_user function.

SC-23 Session Authenticity partial match
prevent

Protects session authenticity and integrity, reducing impact of expired or manipulated sessions in the proxy auth component.

IA-11 Re-authentication partial match
prevent

Requires periodic re-authentication, limiting the window of exposure from insufficient session expiration.

Mitigating Controls (NIST CSF 2.0) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.AA-01 mostly match
prevents

Credential lifecycle management directly includes enforcing session expiration to prevent reuse.

PR.AA-05 mostly match
prevents

Authorization policy enforcement and review covers terminating stale sessions to limit access scope.

PR.AA-03 partial match
prevents

Authentication mechanisms can incorporate session timeout checks but do not inherently address expiration policy.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

A.8.5 Secure authentication none match
none

Automatic termination of inactive sessions and limits on connection duration shrink the window during which a hijacked or unattended authenticated session can be exploited.
