{"id":"CVE-2026-32755","state":"PUBLISHED","title":"Admidio is Missing CSRF Protection on Role Membership Date Changes","description":"Admidio is an open-source user management solution. In versions 5.0.6 and below, the save_membership action in modules/profile/profile_function.php saves changes to a member's role membership start and end dates but does not validate the CSRF token. The handler checks stop_membership and remove_former_membership against the CSRF token but omits save_membership from that check. Because membership UUIDs appear in the HTML source visible to authenticated users, an attacker can embed a crafted POST form on any external page and trick a role leader into submitting it, silently altering membership dates for any member of roles the victim leads. A role leader's session can be silently exploited via CSRF to manipulate any member's membership dates, terminating access by backdating, covertly extending unauthorized access, or revoking role-restricted features, all without confirmation, notification, or administrative approval. This issue has been fixed in version 5.0.7.","publishedAt":"2026-03-19T22:53:09.081Z","updatedAt":"2026-03-25T14:52:11.101Z","severity":{"score":5.7,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:N/I:H/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["Admidio admidio"],"affected":[{"vendor":"Admidio","product":"admidio","versions":[{"version":"< 5.0.7","status":"affected"}]}],"references":["https://github.com/Admidio/admidio/security/advisories/GHSA-h8gr-qwr6-m9gx","https://github.com/Admidio/admidio/releases/tag/v5.0.7"],"weaknesses":["CWE-352"],"ingestedAt":"2026-10-29T20:11:40.391Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/32xxx/CVE-2026-32755.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-32755","state":"PUBLISHED","datePublished":"2026-03-19T22:53:09.081Z","dateUpdated":"2026-03-25T14:52:11.101Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-03-13T18:53:03.532Z"},"containers":{"cna":{"title":"Admidio is Missing CSRF Protection on Role Membership Date Changes","descriptions":[{"lang":"en","value":"Admidio is an open-source user management solution.
