{"id":"CVE-2026-92622","state":"PUBLISHED","title":"Strong Testimonials <= 3.3.8 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'lightbox_class' Shortcode Attribute","description":"The Strong Testimonials plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'lightbox_class' Shortcode Attribute in all versions up to, and including, 3.3.8 due to insufficient input sanitization and output escaping. 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. Exploitation requires that the targeted testimonial view has at least one published testimonial with a featured image and the lightbox wrapper enabled, as the vulnerable code path is only reached when a thumbnail is rendered.","publishedAt":"2026-09-18T07:40:00.882Z","updatedAt":"2026-09-18T19:35:57.073Z","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":["wpchill Strong Testimonials"],"affected":[{"vendor":"wpchill","product":"Strong Testimonials","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"3.3.8","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/52a92e3c-cb64-4fc5-9248-6f4fc2a6a3cc?source=cve","https://plugins.trac.wordpress.org/browser/strong-testimonials/tags/3.3.8/includes/functions-image.php#L70","https://plugins.trac.wordpress.org/browser/strong-testimonials/tags/3.3.8/includes/class-strong-testimonials-view-shortcode.php#L60","https://plugins.trac.wordpress.org/browser/strong-testimonials/tags/3.3.8/includes/class-strong-testimonials-render.php#L723","https://plugins.trac.wordpress.org/changeset?reponame=&old=3699887%40strong-testimonials&new=3699887%40strong-testimonials"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:13:34.582Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/92xxx/CVE-2026-92622.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-92622","state":"PUBLISHED","datePublished":"2026-09-18T07:40:00.882Z","dateUpdated":"2026-09-18T19:35:57.073Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-09-16T14:58:54.869Z"},"containers":{"cna":{"title":"Strong Testimonials <= 3.3.8 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'lightbox_class' Shortcode Attribute","descriptions":[{"lang":"en","value":"The Strong Testimonials plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'lightbox_class' Shortcode Attribute in all versions up to, and including, 3.3.8 due to insufficient input sanitization and output escaping.
