{"id":"CVE-2025-52469","summary":"Chamilo: Friend Request Workflow Bypass - Unauthorized Friend Addition and ID Validation Bypass","details":"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.","aliases":["GHSA-m5xj-5xf3-rqch"],"modified":"2026-08-12T03:51:32.710988102Z","published":"2026-03-02T15:48:24.706Z","database_specific":{"cwe_ids":["CWE-841"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/52xxx/CVE-2025-52469.json","cna_assigner":"GitHub_M"},"references":[{"type":"WEB","url":"https://github.com/chamilo/chamilo-lms/releases/tag/v1.11.30"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/52xxx/CVE-2025-52469.json"},{"type":"ADVISORY","url":"https://github.com/chamilo/chamilo-lms/security/advisories/GHSA-m5xj-5xf3-rqch"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-52469"},{"type":"FIX","url":"https://github.com/chamilo/chamilo-lms/commit/39e0fa88a2ba5dd197e0d8ce7335730b666992a6"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/chamilo/chamilo-lms","events":[{"introduced":"0"},{"fixed":"f748d50e9e6f3d9262a7f9f7d76447d433c64170"},{"fixed":"39e0fa88a2ba5dd197e0d8ce7335730b666992a6"}],"database_specific":{"cpe":"cpe:2.3:a:chamilo:chamilo_lms:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"fixed":"1.11.30"}],"source":["CPE_RANGE","REFERENCES"]}}],"versions":["v1.11.30-rc.1","v1.11.28","v1.11.26","v1.11.26-rc.1","v1.11.24","v1.11.22","v1.11.22-beta.2","v1.11.22-beta.1","v1.11.20-beta.1","v1.11.20","v1.11.18","v1.11.14","v1.11.14-beta.1","v1.11.12","v1.11.10","v1.11.6","v1.11.6-alpha.1","v1.9.8","CHAMILO_1_9_6_STABLE","CHAMILO_1_9_6_RC_2","CHAMILO_1_9_6_RC_1","CHAMILO_1_9_4_STABLE","CHAMILO_1_9_4_RC_1","CHAMILO_1_9_4_ALPHA_1","CHAMILO_1_9_2_STABLE_QUARTER","CHAMILO_1_9_2_STABLE","CHAMILO_1_9_0_STABLE_3","CHAMILO_1_9_0_STABLE_2","CHAMILO_1_9_0_RC_1","CHAMILO_1_8_8_4_STABLE","CHAMILO_1_9_0_ALPHA_4","CHAMILO_1_9_0_ALPHA_2","CHAMILO_1_9_0_ALPHA_1","CHAMILO_1_9_0_PRE_ALPHA","CHAMILO_1_8_8.3_STABLE_4","CHAMILO_1_8_8_2_STABLE_2","CHAMILO_1_8_8_2_STABLE","CHAMILO_1_8_8_2_RC_1","CHAMILO_1_8_8_BETA_2","CHAMILO_1_8_8_BETA_1","CHAMILO_1_8_8_ALPHA","CHAMILO_1_8_7_STABLE_BIS","CHAMILO_1_8_7_STABLE","CHAMILO_1_8_7_RC2","CHAMILO_1_8_7_RC_1","CHAMILO_1_8_7_ALPHA_2","CHAMILO_1_8_7_ALPHA_1","v1.8.6.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-52469.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:H/A:N"}]}
