{"id":"CVE-2026-2505","state":"PUBLISHED","title":"Categories Images <= 3.3.1 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'z_taxonomy_image' Shortcode","description":"The Categories Images plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 3.3.1, via the 'z_taxonomy_image' shortcode. This is due to the shortcode rendering path passing attacker-controlled class input into a fallback image builder that concatenates HTML attributes without proper escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts that execute when users interact with the injected frontend page via the 'class' shortcode attribute.","publishedAt":"2026-04-18T09:26:52.654Z","updatedAt":"2026-04-20T13:46:07.918Z","severity":{"score":5.4,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["elzahlan Categories Images"],"affected":[{"vendor":"elzahlan","product":"Categories Images","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"3.3.1","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/34fb64d5-e152-4950-9ef4-6d53a97a56fb?source=cve","https://plugins.trac.wordpress.org/changeset/3499275/categories-images"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:11:31.369Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/2xxx/CVE-2026-2505.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-2505","state":"PUBLISHED","datePublished":"2026-04-18T09:26:52.654Z","dateUpdated":"2026-04-20T13:46:07.918Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-02-13T22:28:22.061Z"},"containers":{"cna":{"title":"Categories Images <= 3.3.1 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'z_taxonomy_image' Shortcode","descriptions":[{"lang":"en","value":"The Categories Images plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 3.3.1, via the 'z_taxonomy_image' shortcode.
