{"id":"CVE-2026-1921","state":"PUBLISHED","title":"Loco Translate <= 2.8.2 - Authenticated (Translator+) Path Traversal to Limited File Read via 'ref' Parameter","description":"The Loco Translate plugin for WordPress is vulnerable to Path Traversal in all versions up to, and including, 2.8.2 via the `fsReference` AJAX route. This is due to the `findSourceFile()` method normalizing user-supplied `ref` paths containing `../` directory traversal sequences without validating that the resolved path remains within the intended bundle or content directory. This makes it possible for authenticated attackers, with Translator-level access and above (custom `loco_admin` capability required, granted to the `translator` role and administrators by default), to read arbitrary `.php`, `.js`, `.json`, and `.twig` files from the server filesystem outside the intended translation directory. Files named wp-config.php are excluded.","publishedAt":"2026-05-05T02:26:59.132Z","updatedAt":"2026-05-06T12:27:43.824Z","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":["timwhitlock Loco Translate"],"affected":[{"vendor":"timwhitlock","product":"Loco Translate","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"2.8.2","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/f9ff3058-a08c-40ed-b756-81e703b2277a?source=cve","https://plugins.trac.wordpress.org/browser/loco-translate/tags/2.8.1/src/ajax/FsReferenceController.php#L12","https://plugins.trac.wordpress.org/browser/loco-translate/trunk/src/ajax/FsReferenceController.php#L12","https://plugins.trac.wordpress.org/browser/loco-translate/tags/2.8.1/src/ajax/FsReferenceController.php#L92","https://plugins.trac.wordpress.org/browser/loco-translate/trunk/src/ajax/FsReferenceController.php#L92","https://plugins.trac.wordpress.org/changeset/3482475/loco-translate/trunk/tpl/admin/config/version.php","https://plugins.trac.wordpress.org/changeset?old_path=%2Floco-translate/tags/2.8.2&new_path=%2Floco-translate/tags/2.8.3"],"weaknesses":["CWE-22"],"ingestedAt":"2026-10-29T20:11:10.572Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/1xxx/CVE-2026-1921.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-1921","state":"PUBLISHED","datePublished":"2026-05-05T02:26:59.132Z","dateUpdated":"2026-05-06T12:27:43.824Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-02-04T17:33:59.876Z"},"containers":{"cna":{"title":"Loco Translate <= 2.8.2 - Authenticated (Translator+) Path Traversal to Limited File Read via 'ref' Parameter","descriptions":[{"lang":"en","value":"The Loco Translate plugin for WordPress is vulnerable to Path Traversal in all versions up to, and including, 2.8.2 via the `fsReference` AJAX route.
