{"id":"CVE-2026-4085","state":"PUBLISHED","title":"Easy Social Photos Gallery <= 3.1.2 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'wrapper_class' Shortcode Attribute","description":"The Easy Social Photos Gallery plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'wrapper_class' shortcode attribute of the 'my-instagram-feed' shortcode in all versions up to, and including, 3.1.2. This is due to insufficient input sanitization and output escaping on user supplied attributes. Specifically, the plugin uses sanitize_text_field() instead of esc_attr() when outputting the 'wrapper_class' attribute inside a double-quoted HTML class attribute. Since sanitize_text_field() does not encode double quotes, an attacker can break out of the class attribute and inject arbitrary HTML event handlers. 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":"2026-04-22T07:45:38.938Z","updatedAt":"2026-04-22T18:30:36.223Z","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":["maltathemes Easy Social Photos Gallery – MIF"],"affected":[{"vendor":"maltathemes","product":"Easy Social Photos Gallery – MIF","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"3.1.2","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/8640724c-0bd4-4684-9fd1-027f2af64e67?source=cve","https://plugins.trac.wordpress.org/browser/my-instagram-feed/tags/3.1.2/frontend/class-my-instagram-feed-frontend.php#L53","https://plugins.trac.wordpress.org/browser/my-instagram-feed/trunk/frontend/views/feed.php#L102","https://plugins.trac.wordpress.org/browser/my-instagram-feed/tags/3.1.2/frontend/views/feed.php#L102","https://plugins.trac.wordpress.org/browser/my-instagram-feed/trunk/frontend/class-my-instagram-feed-frontend.php#L53"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:12:16.098Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/4xxx/CVE-2026-4085.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-4085","state":"PUBLISHED","datePublished":"2026-04-22T07:45:38.938Z","dateUpdated":"2026-04-22T18:30:36.223Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-03-12T20:51:56.076Z"},"containers":{"cna":{"title":"Easy Social Photos Gallery <= 3.1.2 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'wrapper_class' Shortcode Attribute","descriptions":[{"lang":"en","value":"The Easy Social Photos Gallery plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'wrapper_class' shortcode attribute of the 'my-instagram-feed' shortcode in all versions up to, and including, 3.1.2.
