What is CVE-2026-22687?

The WeKnora framework, designed for advanced document comprehension and semantic querying, contains a vulnerability that arises when the Agent service is activated. Prior to version 0.2.5, insufficient validation on the backend allows malicious users to exploit prompt-based bypass methods. This exploitation enables attackers to circumvent established query restrictions, potentially accessing confidential data from the server and database. Tencent has addressed this vulnerability with patches in version 0.2.5 to enhance security and protect sensitive information.
