CVE-2026-34082: CWE-863: Incorrect Authorization in langgenius dify
CVE-2026-34082 is an authorization vulnerability in the open-source LLM app development platform Dify prior to version 1. 13. 1. The DELETE API endpoint for removing conversations does not properly verify user permissions, allowing any authenticated user to delete chat histories belonging to other users. This issue is fixed in version 1. 13. 1. The vulnerability has a medium severity rating with a CVSS 4. 0 base score of 5. 3.
AI Analysis
Technical Summary
Dify versions before 1.13.1 contain an incorrect authorization flaw (CWE-863) in the DELETE /console/api/installed-apps/<appId>/conversations/<conversationId> endpoint. Authenticated users with limited privileges can delete conversations owned by other users because the authorization checks are insufficient. This could lead to unauthorized deletion of chat histories. The issue is resolved in version 1.13.1. The CVSS 4.0 vector indicates network attack vector, low attack complexity, no user interaction, and low impact on confidentiality and integrity but no impact on availability.
Potential Impact
An attacker with authenticated access to Dify can delete chat conversations belonging to other users, potentially causing data loss and disruption of user experience. There is no indication of confidentiality or availability impact beyond deletion of chat history. No known exploits are reported in the wild.
Mitigation Recommendations
Upgrade Dify to version 1.13.1 or later, where the authorization checks for the DELETE conversation API have been corrected. Since this is an open-source product and not a cloud service, manual patching by upgrading is required. Patch status is confirmed by the vendor's versioning information.
