{"id":"CVE-2026-55593","state":"PUBLISHED","title":"Froxlor: CSRF Vulnerability in Froxlor AJAX Endpoint — Missing Cross-Site Request Forgery Protection","description":"Froxlor is open source server administration software. Prior to 2.3.8, the standalone lib/ajax.php entry point bypasses the centralized request validation in lib/init.php, and Ajax::handle in lib/Froxlor/Ajax/Ajax.php checks only for a valid session before routing state-changing requests. The editapikey action in Ajax::editApiKey updates allowed_from and valid_until without validating a CSRF token, while templates/Froxlor/assets/js/jquery/apikeys.js sends no token because the endpoint does not require one. An unauthenticated attacker can induce an authenticated administrator's browser to submit a forged request that adds an attacker-controlled address to an API key's allowed_from list or removes its expiration, weakening the key's security restrictions. This issue is fixed in version 2.3.8.","publishedAt":"2026-08-18T20:18:01.526Z","updatedAt":"2026-08-19T18:20:14.720Z","severity":{"score":6.5,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["froxlor froxlor"],"affected":[{"vendor":"froxlor","product":"froxlor","versions":[{"version":"< 2.3.8","status":"affected"}]}],"references":["https://github.com/froxlor/froxlor/security/advisories/GHSA-xpr4-8vp6-c87j","https://github.com/froxlor/froxlor/commit/5f540fe361e7e13e8c5a32805b793a25e9e26a0e","https://github.com/froxlor/froxlor/releases/tag/2.3.8"],"weaknesses":["CWE-352"],"ingestedAt":"2026-10-29T20:12:24.861Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/55xxx/CVE-2026-55593.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-55593","state":"PUBLISHED","datePublished":"2026-08-18T20:18:01.526Z","dateUpdated":"2026-08-19T18:20:14.720Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-06-16T23:18:03.170Z"},"containers":{"cna":{"title":"Froxlor: CSRF Vulnerability in Froxlor AJAX Endpoint — Missing Cross-Site Request Forgery Protection","descriptions":[{"lang":"en","value":"Froxlor is open source server administration software.
