This is due to the `fancybox-config.js` script reading the carousel container's `id` attribute directly from the DOM to construct a jQuery selector without sanitization. When a Contributor crafts an HTML block with a malformed carousel container ID (containing characters invalid for jQuery selectors), the custom fancybox configuration throws a JavaScript error and fails to initialize. This causes the bundled fancybox library (v3.5.7) to fall back to its default caption handling, which renders the `data-caption` attribute content as raw HTML. Since WordPress allows `data-*` attributes through `wp_kses_post()`, 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 clicks an image in the crafted carousel lightbox."}],"title":"WP Carousel Free <= 2.7.10 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'data-caption' Attribute","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/e75815a3-2414-47f3-b0c4-e5d3e2cb369d?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/wp-carousel-free/tags/2.7.10/public/js/fancybox-config.js#L3"},{"url":"https://plugins.trac.wordpress.org/browser/wp-carousel-free/trunk/public/js/fancybox-config.js#L3"},{"url":"https://plugins.trac.wordpress.org/changeset/3506878/wp-carousel-free/trunk/public/js/fancybox.js"}],"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":"Craig Smith"}],"timeline":[{"time":"2026-03-25T10:41:25.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-05-04T15:01:27.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-05-05T13:46:57.590436Z","id":"CVE-2026-4665","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":"2026-05-05T14:13:17.289Z"}}]}}
