In 2.10.2-lts and earlier, management chat-record routes authorize the path application_id but load records using global chat_id and chat_record_id values without confirming that the chat belongs to the authorized application. A normal user in the same workspace who knows the chat_id of a persisted non-debug record for a victim's published application can place it under a separate attacker-owned application path to read victim chat records. An attacker with an owned knowledge base and document can also use add_knowledge to copy victim answers while updating the victim record's improve_paragraph_id_list. No fixed version is available as of this review.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"twilight","depthScore":35,"depthScoreParts":{"impact":23.1,"likelihood":0,"exploitation":12,"ransomware":0},"changes":[{"seq":210427,"id":"CVE-2026-77525","ts":1790290511780,"field":"exploit_available","old":"false","new":"true"}]}
