In modules/pfs/inc/pfs.editfolder.php, the folder update action ('a=update') updates folder metadata (title, description, public/gallery flags) without calling cot_check_xg() to validate the anti-CSRF token. A remote attacker who lures an authenticated user into visiting a malicious page can force the browser to submit a forged request that modifies the victim's folder metadata, including making a private folder public.","severity":"medium","score":5.4,"published":"2026-06-18T12:40:26.000Z","modified":"2026-09-10T03:50:49.890Z","withdrawn":false,"knownExploited":false,"affected":[{"ecosystem":"Packagist","name":"cotonti/cotonti","sources":[{"name":"OSV · GHSA-hp3v-wp32-953h","url":"https://osv.dev/vulnerability/GHSA-hp3v-wp32-953h"}],"ranges":[{"events":[{"introduced":"0"},{"last_affected":"1.0.0"}],"type":"ECOSYSTEM"}],"versions":["0.9.23","0.9.24","0.9.24.1","0.9.24.2","0.9.25","1.0.0"],"fixed":[]}],"sourceAffected":[],"references":["https://nvd.nist.gov/vuln/detail/CVE-2026-55745","https://github.com/Cotonti/Cotonti","https://github.com/Cotonti/Cotonti/blob/f43f1fc38ba4e02027786dad9dac1435c7c52b30/modules/pfs/inc/pfs.editfolder.php#L90"],"sources":[{"name":"OSV","id":"GHSA-hp3v-wp32-953h","modified":"2026-09-10T03:50:49.890849672Z","url":"https://osv.dev/vulnerability/GHSA-hp3v-wp32-953h"}],"assessments":[{"source":"OSV","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N","score":5.4},{"source":"OSV","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N","score":5.3}],"products":[],"remediation":[],"kev":{"status":"not-listed","checkedAt":"2026-10-28T19:15:31.108Z"},"coverage":[{"source":"NVD","status":"not-checked"},{"source":"GHSA","status":"not-checked"},{"source":"EUVD","status":"not-checked"},{"source":"EPSS","status":"not-checked"}],"evidence":[]}
