CVE-2026-12772
Description
A flaw was found in BerriAI litellm. A remote attacker could exploit a vulnerability in the authenticate_user function within the PROXY_ADMIN database API Key Generator component. By performing a specific manipulation, an attacker can cause session expiration for users, leading to a denial of service for affected sessions.
Statement
This Moderate impact flaw in BerriAI litellm allows a remote attacker to trigger session expiration by manipulating the authenticate_user function within the PROXY_ADMIN database API Key Generator. This can lead to a denial of service for affected user sessions in Red Hat OpenShift AI and Red Hat Ansible Automation Platform, impacting availability rather than data integrity or confidentiality.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.

Understanding the Weakness (CWE)
Confidentiality
Technical Impact: Read Application Data; Read Memory
If the released resource is subsequently reused or reallocated, then a read operation on the original resource might access sensitive data that is associated with a different user or entity.
Availability
Technical Impact: DoS: Crash, Exit, or Restart
When the resource is released, the software might modify some of its structure, or close associated channels (such as a file descriptor). When the software later accesses the resource as if it is valid, the resource might not be in an expected state, leading to resultant errors that may lead to a crash.
Integrity,Confidentiality,Availability
Technical Impact: Execute Unauthorized Code or Commands; Modify Application Data; Modify Memory
When the resource is released, the software might modify some of its structure. This might affect logic in the sections of code that still assume the resource is active. If the released resource is related to memory and is used in a function call, or points to unexpected data in a write operation, then code execution may be possible upon subsequent accesses.
