Berriai · Litellm · CVE-2026-12771
**Name of the Vulnerable Software and Affected Versions**
BerriAI litellm versions prior to 1.82.3
**Description**
An issue in the M2M JWT Handler component, specifically within the file `litellm/proxy/auth/user api key auth.py`, leads to improper authorization. This flaw allows a remote attacker to bypass authorization mechanisms, although the attack is characterized by high complexity and difficult exploitability.
**Recommendations**
Update to a version later than 1.82.2.
As a temporary workaround, restrict access to the `litellm/proxy/auth/user api key auth.py` file or the M2M JWT Handler component to minimize the risk of exploitation.
