What is CVE-2026-21484?

The AnythingLLM application, a tool that provides context references for large language models, contains a vulnerability in its password recovery functionality. This flaw allows attackers to determine whether a specific username exists by interpreting different error messages returned based on username validity, potentially compromising account security. This issue was addressed in a commit that harmonized the error messages returned by the password recovery endpoint, thereby mitigating the risk of username enumeration attacks.
