{"id":"CVE-2026-4766","state":"PUBLISHED","title":"Easy Image Gallery <= 1.5.3 - Authenticated (Contributor+) Stored Cross-Site Scripting via Gallery Shortcode Post Meta","description":"The Easy Image Gallery plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Gallery shortcode post meta field in all versions up to, and including, 1.5.3. This is due to insufficient input sanitization and output escaping on user-supplied gallery shortcode values. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.","publishedAt":"2026-03-25T01:25:06.425Z","updatedAt":"2026-04-08T17:30:19.810Z","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":["devrix Easy Image Gallery"],"affected":[{"vendor":"devrix","product":"Easy Image Gallery","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.5.3","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/e7279f74-c2bd-4601-b8d5-0effe43705a5?source=cve","https://plugins.trac.wordpress.org/browser/easy-image-gallery/trunk/includes/template-functions.php#L240","https://plugins.trac.wordpress.org/browser/easy-image-gallery/tags/1.5.3/includes/template-functions.php#L240"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:12:16.098Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/4xxx/CVE-2026-4766.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-4766","state":"PUBLISHED","datePublished":"2026-03-25T01:25:06.425Z","dateUpdated":"2026-04-08T17:30:19.810Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-03-24T12:52:49.026Z"},"containers":{"cna":{"title":"Easy Image Gallery <= 1.5.3 - Authenticated (Contributor+) Stored Cross-Site Scripting via Gallery Shortcode Post Meta","descriptions":[{"lang":"en","value":"The Easy Image Gallery plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Gallery shortcode post meta field in all versions up to, and including, 1.5.3.
