{"id":"CVE-2026-15601","state":"PUBLISHED","title":"Kirki <= 6.0.13 - Authenticated (Editor+) Path Traversal to Arbitrary File Write (Zip Slip)","description":"The Kirki – Freeform Page Builder, Website Builder & Customizer plugin for WordPress is vulnerable to Path Traversal (Zip Slip) in all versions up to, and including, 6.0.13 via the extract_zip_file function.

The install_app, update_app, and get_kirki_template_from_zip code paths accept a user-supplied app src value to construct the download URL, and no sanitization is applied to prevent a crafted ZIP from being fetched and extracted with path-traversing entry names that escape the intended destination directory.","publishedAt":"2026-08-01T07:49:46.331Z","updatedAt":"2026-08-03T18:36:23.813Z","severity":{"score":4.9,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["themeum Kirki – Freeform Page Builder, Website Builder & Customizer"],"affected":[{"vendor":"themeum","product":"Kirki – Freeform Page Builder, Website Builder & Customizer","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"6.0.13","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/4ccd1314-b9b9-4f63-820c-2817a4932ee8?source=cve","https://plugins.trac.wordpress.org/browser/kirki/tags/6.0.13/app/Supports/FileHandler.php#L90","https://plugins.trac.wordpress.org/browser/kirki/tags/6.0.13/app/Services/AppsService.php#L113","https://plugins.trac.wordpress.org/browser/kirki/tags/6.0.13/app/Services/AppsService.php#L186","https://plugins.trac.wordpress.org/browser/kirki/tags/6.0.13/app/Http/Controllers/Api/AppsController.php#L27","https://plugins.trac.wordpress.org/browser/kirki/tags/6.0.13/routes/api.php#L77","https://plugins.trac.wordpress.org/browser/kirki/tags/6.0.13/includes/Ajax/Apps.php#L176","https://plugins.trac.wordpress.org/browser/kirki/tags/6.0.12/app/Supports/FileHandler.php#L90","https://plugins.trac.wordpress.org/browser/kirki/tags/6.0.12/app/Services/AppsService.php#L113","https://plugins.trac.wordpress.org/browser/kirki/tags/6.0.12/app/Services/AppsService.php#L186","https://plugins.trac.wordpress.org/browser/kirki/tags/6.0.12/app/Http/Controllers/Api/AppsController.php#L27","https://plugins.trac.wordpress.org/browser/kirki/tags/6.0.12/routes/api.php#L77","https://plugins.trac.wordpress.org/browser/kirki/tags/6.0.12/includes/Ajax/Apps.php#L176","https://plugins.trac.wordpress.org/changeset?reponame=&old=3617070%40kirki&new=3617070%40kirki"],"weaknesses":["CWE-22"],"ingestedAt":"2026-10-29T20:11:00.674Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/15xxx/CVE-2026-15601.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-15601","state":"PUBLISHED","datePublished":"2026-08-01T07:49:46.331Z","dateUpdated":"2026-08-03T18:36:23.813Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-07-13T14:36:34.396Z"},"containers":{"cna":{"title":"Kirki <= 6.0.13 - Authenticated (Editor+) Path Traversal to Arbitrary File Write (Zip Slip)","descriptions":[{"lang":"en","value":"The Kirki – Freeform Page Builder, Website Builder & Customizer plugin for WordPress is vulnerable to Path Traversal (Zip Slip) in all versions up to, and including, 6.0.13 via the extract_zip_file function.
