{"id":"CVE-2025-52469","state":"PUBLISHED","title":"Chamilo: Friend Request Workflow Bypass - Unauthorized Friend Addition and ID Validation Bypass","description":"Chamilo is a learning management system. Prior to version 1.11.30, a logic vulnerability in the friend request workflow of Chamilo’s social network module allows an authenticated user to forcibly add any user as a friend by directly calling the AJAX endpoint. The attacker can bypass the normal flow of sending and accepting friend requests, and even add non-existent users. This breaks access control and social interaction logic, with potential privacy implications. This issue has been patched in version 1.11.30.","publishedAt":"2026-03-02T15:48:24.706Z","updatedAt":"2026-03-02T20:18:16.099Z","severity":{"score":7.1,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:H/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["chamilo chamilo-lms"],"affected":[{"vendor":"chamilo","product":"chamilo-lms","versions":[{"version":"< 1.11.30","status":"affected"}]}],"references":["https://github.com/chamilo/chamilo-lms/security/advisories/GHSA-m5xj-5xf3-rqch","https://github.com/chamilo/chamilo-lms/commit/39e0fa88a2ba5dd197e0d8ce7335730b666992a6","https://github.com/chamilo/chamilo-lms/releases/tag/v1.11.30"],"weaknesses":["CWE-841"],"ingestedAt":"2026-10-29T20:09:31.862Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2025/52xxx/CVE-2025-52469.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2025-52469","state":"PUBLISHED","datePublished":"2026-03-02T15:48:24.706Z","dateUpdated":"2026-03-02T20:18:16.099Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2025-06-17T02:28:39.716Z"},"containers":{"cna":{"title":"Chamilo: Friend Request Workflow Bypass - Unauthorized Friend Addition and ID Validation Bypass","descriptions":[{"lang":"en","value":"Chamilo is a learning management system.
