{"id":"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.","aliases":["GHSA-86hp-hf3j-3m8r"],"modified":"2026-07-15T01:49:12.198114498Z","published":"2026-06-18T06:46:57.622Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/55xxx/CVE-2026-55746.json","cna_assigner":"TuranSec","cwe_ids":["CWE-79"]},"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"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/cotonti/cotonti","events":[{"introduced":"0d554e939a315e7f7f18fba3ca1132b80c6a1adb"},{"last_affected":"0d554e939a315e7f7f18fba3ca1132b80c6a1adb"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"1.0.0"},{"last_affected":"1.0.0"}]}}],"versions":["1.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-55746.json"}}],"schema_version":"1.7.5","severity":[{"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"}]}
