{"id":"CVE-2026-45233","summary":"HTMLy CMS 3.1.1 Path Traversal via oldfile Parameter in Autosave","details":"HTMLy CMS through 3.1.1 contains a path traversal vulnerability that allows low-privileged authenticated attackers to relocate arbitrary files by supplying directory traversal sequences in the oldfile parameter at the admin autosave endpoint. Attackers can pass unsanitized traversal sequences directly to file_exists() and rename() functions in admin.php without canonicalization or directory boundary enforcement to cause unintended relocation of any file writable by the web server process to an attacker-specified draft location.","modified":"2026-07-16T03:30:58.933063001Z","published":"2026-06-25T15:50:00.181Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/45xxx/CVE-2026-45233.json","cna_assigner":"VulnCheck","cwe_ids":["CWE-22"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/45xxx/CVE-2026-45233.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-45233"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/htmly-cms-path-traversal-via-oldfile-parameter-in-autosave"},{"type":"PACKAGE","url":"https://github.com/danpros/htmly"},{"type":"EVIDENCE","url":"https://gist.github.com/mrgr4yhat/c4df971eafa272ac8c86c15e2829b7fe"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/danpros/htmly","events":[{"introduced":"0"},{"last_affected":"dde01601bd9e64eaff695814d03c1f31d9eb8f37"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"last_affected":"3.1.1"}],"source":"AFFECTED_FIELD"}}],"versions":["v3.1.1","v3.1.0","v3.0.9","v3.0.8","v3.0.7","v3.0.6","v3.0.5","v3.0.4","v3.0.3","v3.0.2","v3.0.1","v3.0.0","v2.9.9","v2.9.8","v2.9.7","v2.9.6","v2.9.5","v2.9.4","v2.9.3","v2.9.2","v2.9.1","v2.9.0","v2.8.9","v2.8.8","v2.8.7","v.2.8.6","v2.8.5","v2.8.4","v2.8.3","v2.8.2","v2.8.1","v2.8.0","v2.7.9","v2.7.8","v2.7.7","v2.7.6","v2.7.5","v2.7.4","v2.7.3","v2.7.2","v2.7.1","v2.7.0","v2.6.9","v2.6.8","v2.6.7","v2.6.6","v2.6.5","v2.6.4","v2.6.3","v2.6.2","v2.6.1","v2.6.0","v2.5.9","v2.5.8","v2.5.7","v2.5.6","v2.5.5","v2.5.4","v2.5.3","v2.5.2","v2.4.1","v2.5.1","v2.5","v2.4","v2.3","v2.2","v2.1","v2.0","v1.9","v1.8","v1.7","v1.6","v1.5","v1.1","v1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-45233.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
