{"id":"CVE-2026-5361","state":"PUBLISHED","title":"Envira Gallery <= 1.12.4 - Authenticated (Author+) Stored Cross-Site Scripting via 'arrows' Parameter","description":"The Envira Gallery Lite plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the REST API in versions up to and including 1.12.4. This is due to insufficient input sanitization in the update_gallery_data() function and improper output escaping in the gallery_init() function. The sanitize_config_values() function only sanitizes the justified_gallery_theme and justified_row_height parameters, but does not sanitize the arrows parameter. When the arrows value is output in the inline JavaScript configuration, it uses esc_attr() which is designed for HTML attribute contexts, not JavaScript contexts, allowing JavaScript expression injection. This makes it possible for authenticated attackers, with Author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.","publishedAt":"2026-05-14T03:27:15.137Z","updatedAt":"2026-05-14T10:47:27.431Z","severity":{"score":6.4,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["smub Envira Gallery – Image Photo Gallery, Albums, Video Gallery, Slideshows & More"],"affected":[{"vendor":"smub","product":"Envira Gallery – Image Photo Gallery, Albums, Video Gallery, Slideshows & More","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.12.4","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/d2b1e973-f22d-4e69-b3b8-d6ea5df3f047?source=cve","https://plugins.trac.wordpress.org/browser/envira-gallery-lite/trunk/includes/global/shortcode.php#L1067","https://plugins.trac.wordpress.org/browser/envira-gallery-lite/tags/1.12.4/includes/global/shortcode.php#L1067","https://plugins.trac.wordpress.org/browser/envira-gallery-lite/trunk/includes/global/rest.php#L163","https://plugins.trac.wordpress.org/browser/envira-gallery-lite/tags/1.12.4/includes/global/rest.php#L163","https://plugins.trac.wordpress.org/changeset/3514026/envira-gallery-lite/trunk/includes/global/shortcode.php?old=3465371&old_path=envira-gallery-lite%2Ftrunk%2Fincludes%2Fglobal%2Fshortcode.php"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:12:32.778Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/5xxx/CVE-2026-5361.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-5361","state":"PUBLISHED","datePublished":"2026-05-14T03:27:15.137Z","dateUpdated":"2026-05-14T10:47:27.431Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-04-01T17:20:59.284Z"},"containers":{"cna":{"title":"Envira Gallery <= 1.12.4 - Authenticated (Author+) Stored Cross-Site Scripting via 'arrows' Parameter","descriptions":[{"lang":"en","value":"The Envira Gallery Lite plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the REST API in versions up to and including 1.12.4.
