DescriptionCVE.org

A vulnerability was identified in BerriAI litellm up to 1.82.2. This impacts the function get_redirect_response_from_openid of the file litellm/proxy/management_endpoints/ui_sso.py of the component SSO Authentication Flow. The manipulation leads to session expiration. The attack is possible to be carried out remotely. The exploit is publicly available and might be used. The vendor was contacted early about this disclosure.

AnalysisAI

Insufficient session expiration in LiteLLM's SSO authentication flow exposes deployments running versions 1.82.0 through 1.82.2 to unauthorized persistent session access by low-privileged authenticated users. The flaw resides in the get_redirect_response_from_openid function within the OpenID Connect callback handling code, allowing manipulation of the SSO redirect response to bypass session lifetime enforcement. …

Vulnerability AssessmentAI

Exploitation Exploitation strictly requires a valid low-privilege authenticated session against the LiteLLM proxy - the CVSS 4.0 vector explicitly encodes PR:L, confirming authentication is mandatory and unauthenticated exploitation is not possible. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 base score of 2.1 - one of the lowest possible - accurately reflects the constrained exploitation conditions: the attacker must already hold a low-privilege authenticated session (PR:L), and impacts are uniformly low across confidentiality, integrity, and availability (VC:L/VI:L/VA:L). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An authenticated LiteLLM proxy user with low-privilege SSO access sends a crafted or replayed OpenID Connect redirect response to the `get_redirect_response_from_openid` endpoint, triggering the insufficient session expiration flaw and causing the server to accept a session that should have been invalidated. A public exploit POC is available at https://gist.github.com/YLChen-007/5fa8af12e1b183674d7ca96d852fb697, significantly lowering the technical barrier. …
Remediation No vendor-released patch with a confirmed exact fix version has been identified in the available data - the fix status from BerriAI is unknown at time of analysis. … Detailed patch versions, workarounds, and compensating controls in full report.
