DescriptionCVE.org

A security flaw has been discovered in BerriAI litellm up to 1.82.2. This impacts the function authenticate_user of the file litellm/proxy/auth/login_utils.py of the component PROXY_ADMIN database API Key Generator. Performing a manipulation results in session expiration. The attack may be initiated remotely. The exploit has been released to the public and may be used for attacks. The vendor was contacted early about this disclosure.

AnalysisAI

Insufficient session expiration in LiteLLM's proxy authentication layer (versions 1.82.0 through 1.82.2) allows remote low-privileged users to reuse or manipulate session tokens generated by the PROXY_ADMIN API Key Generator beyond their intended validity window. The flaw resides in the authenticate_user function within litellm/proxy/auth/login_utils.py, where session/API key lifecycle management does not enforce expiration correctly per CWE-613. …

Vulnerability AssessmentAI

Exploitation Exploitation requires that the attacker already holds a low-privilege account or valid-at-some-point session token within the target LiteLLM proxy deployment (PR:L per CVSS 4.0 vector). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 base vector (AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:L) places this at 2.1 - the lowest tier, reflecting that while network-exploitable without user interaction, it requires at minimum low-privilege access (PR:L) and delivers only limited confidentiality, integrity, and availability impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker with low-level access to a shared LiteLLM proxy deployment - such as a standard API user - obtains their own session token or intercepts a token that should have expired after logout or rotation. Leveraging the public proof-of-concept (https://gist.github.com/YLChen-007/39ed709ce322431658a05b951e91f278), the attacker manipulates the `authenticate_user` flow to present the expired token as valid, gaining continued authenticated access to the proxy API. …
Remediation No vendor-released patched version has been independently confirmed in the available data - the affected range is listed through 1.82.2 with no upper-bound fix version specified in CPE or advisory references. … Detailed patch versions, workarounds, and compensating controls in full report.
