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."}],"title":"Easy Social Photos Gallery <= 3.1.2 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'wrapper_class' Shortcode Attribute","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/8640724c-0bd4-4684-9fd1-027f2af64e67?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/my-instagram-feed/tags/3.1.2/frontend/class-my-instagram-feed-frontend.php#L53"},{"url":"https://plugins.trac.wordpress.org/browser/my-instagram-feed/trunk/frontend/views/feed.php#L102"},{"url":"https://plugins.trac.wordpress.org/browser/my-instagram-feed/tags/3.1.2/frontend/views/feed.php#L102"},{"url":"https://plugins.trac.wordpress.org/browser/my-instagram-feed/trunk/frontend/class-my-instagram-feed-frontend.php#L53"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')","cweId":"CWE-79","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","baseScore":6.4,"baseSeverity":"MEDIUM"}}],"credits":[{"lang":"en","type":"finder","value":"Muhammad Yudha - DJ"}],"timeline":[{"time":"2026-04-21T19:06:46.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-04-22T18:30:21.731097Z","id":"CVE-2026-4085","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-04-22T18:30:36.223Z"}}]}}
