{"id":"CVE-2026-55746","aliases":["GHSA-86hp-hf3j-3m8r"],"url":"https://o3.security/vulnerability/CVE-2026-55746","summary":"Cotonti stored XSS via PFS folder title","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.","published":"2026-06-18T06:46:57.622Z","modified":"2026-08-12T03:51:17.057943500Z","cvss":null,"epss":{"score":0.00171,"percentile":0.06852,"asOf":"2026-09-17"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"cotonti/cotonti","fixedVersion":null}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/55xxx/CVE-2026-55746.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-55746"},{"type":"PACKAGE","url":"https://github.com/Cotonti/Cotonti"},{"type":"ARTICLE","url":"https://github.com/Cotonti/Cotonti/blob/f43f1fc38ba4e02027786dad9dac1435c7c52b30/modules/pfs/inc/pfs.main.php#L396"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:17.057943500Z"}}
