{"id":"GHSA-wx35-cv59-9gwr","summary":"Cotonti: Cross-Site Request Forgery in the Personal File Storage (PFS) module","details":"Cotonti 1.0.0 (master branch, commit f43f1fc3) is vulnerable to Cross-Site Request Forgery in the Personal File Storage (PFS) module. In modules/pfs/inc/pfs.main.php, the file upload action ('a=upload') processes uploaded files without calling cot_check_xg() to validate the anti-CSRF token, even though sibling actions such as 'delete' (line 272) do. A remote attacker who lures an authenticated user into visiting a malicious page can force the browser to submit a forged multipart request that uploads arbitrary files into the victim's PFS storage.","aliases":["CVE-2026-55744"],"modified":"2026-09-10T03:50:51.054919996Z","published":"2026-06-18T12:40:25Z","database_specific":{"github_reviewed":true,"github_reviewed_at":"2026-06-19T14:53:52Z","nvd_published_at":"2026-06-18T08:16:34Z","cwe_ids":["CWE-352"],"severity":"HIGH"},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-55744"},{"type":"PACKAGE","url":"https://github.com/Cotonti/Cotonti"},{"type":"WEB","url":"https://github.com/Cotonti/Cotonti/blob/f43f1fc38ba4e02027786dad9dac1435c7c52b30/modules/pfs/inc/pfs.main.php#L118"}],"affected":[{"package":{"name":"cotonti/cotonti","ecosystem":"Packagist","purl":"pkg:composer/cotonti/cotonti"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"1.0.0"}]}],"versions":["0.9.23","0.9.24","0.9.24.1","0.9.24.2","0.9.25","1.0.0"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/06/GHSA-wx35-cv59-9gwr/GHSA-wx35-cv59-9gwr.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N"}]}
