{"id":"GHSA-86hp-hf3j-3m8r","summary":"Cotonti: Stored Cross-Site Scripting in the Personal File Storage (PFS) module","details":"Cotonti 1.0.0 (master branch, commit f43f1fc3) is vulnerable to stored Cross-Site Scripting in the Personal File Storage (PFS) module. A folder title (pff_title) is imported with the 'TXT' filter, which does not strip or encode HTML (the tag check in cot_import is disabled), so an authenticated user can store HTML/JavaScript in a folder title. In modules/pfs/inc/pfs.main.php the title is assigned to the template variable PFF_ROW_TITLE without htmlspecialchars(), and modules/pfs/tpl/pfs.tpl outputs {PFF_ROW_TITLE} unescaped. When the folder listing is viewed (including by other users for public folders), the injected script executes in the victim's browser.","aliases":["CVE-2026-55746"],"modified":"2026-09-10T03:51:08.120593727Z","published":"2026-06-18T12:40:26Z","database_specific":{"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2026-06-19T14:52:31Z","nvd_published_at":"2026-06-18T08:16:34Z","cwe_ids":["CWE-79"]},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-55746"},{"type":"PACKAGE","url":"https://github.com/Cotonti/Cotonti"},{"type":"WEB","url":"https://github.com/Cotonti/Cotonti/blob/f43f1fc38ba4e02027786dad9dac1435c7c52b30/modules/pfs/inc/pfs.main.php#L396"}],"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-86hp-hf3j-3m8r/GHSA-86hp-hf3j-3m8r.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:L/A:N"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:P/VC:H/VI:L/VA:N/SC:L/SI:L/SA:N"}]}
