{"cve":"CVE-2026-1921","nvd":{"published":"2026-05-05T03:15:59.100","modified":"2026-06-17T10:16:43.470","status":"Deferred","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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N","score":4.9},"cwes":["CWE-22"],"references":["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/tags/2.8.1/src/ajax/FsReferenceController.php#L92","https://plugins.trac.wordpress.org/browser/loco-translate/trunk/src/ajax/FsReferenceController.php#L12","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"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:33:09.003606135+00:00"},"epss":{"cve":"CVE-2026-1921","score":0.0064,"percentile":0.50675,"date":"2026-11-01"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
