{"cve":"CVE-2025-12849","nvd":{"published":"2025-11-15T07:15:42.640","modified":"2026-10-07T21:10:00.200","status":"Deferred","description":"The Contest Gallery plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 28.0.2. This is due to the plugin registering the `cg_check_wp_admin_upload_v10` AJAX action for both authenticated and unauthenticated users without implementing capability checks or nonce verification. This makes it possible for unauthenticated attackers to inject arbitrary WordPress media attachments into galleries and manipulate gallery metadata via the `cg_check_wp_admin_upload_v10` action. It does not enable an attacker to move or upload files.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","score":5.3},"cwes":["CWE-862"],"references":["https://plugins.trac.wordpress.org/browser/contest-gallery/tags/28.0.2/v10/include-functions-v10.php#L42","https://plugins.trac.wordpress.org/browser/contest-gallery/tags/28.0.2/v10/include-functions-v10.php#L47","https://plugins.trac.wordpress.org/browser/contest-gallery/tags/28.0.2/v10/include-functions-v10.php#L64","https://plugins.trac.wordpress.org/browser/contest-gallery/tags/28.0.2/v10/v10-admin/gallery/wp-uploader.php#L15","https://plugins.trac.wordpress.org/browser/contest-gallery/tags/28.0.2/v10/v10-admin/gallery/wp-uploader.php#L173"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:16:02.354564667+00:00"},"epss":{"cve":"CVE-2025-12849","score":0.0034,"percentile":0.27168,"date":"2026-10-25"},"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).
