{"id":"CVE-2026-1275","state":"PUBLISHED","title":"Multi Post Carousel by Category <= 1.4 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'slides' Shortcode Attribute","description":"The Multi Post Carousel by Category plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'slides' shortcode attribute in all versions up to, and including, 1.4. This is due to insufficient input sanitization and output escaping on the user-supplied 'slides' parameter in the post_slides_shortcode function. 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":"2026-03-21T03:26:59.781Z","updatedAt":"2026-04-08T17:16:26.184Z","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":["gbsdeveloper Multi Post Carousel by Category"],"affected":[{"vendor":"gbsdeveloper","product":"Multi Post Carousel by Category","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.4","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/b27ecbf7-e97d-42c0-98d4-c235edf40669?source=cve","https://plugins.trac.wordpress.org/browser/multi-post-carousel/trunk/multi-post-carousel.php#L174","https://plugins.trac.wordpress.org/browser/multi-post-carousel/tags/1.4/multi-post-carousel.php#L174"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:11:10.572Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/1xxx/CVE-2026-1275.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-1275","state":"PUBLISHED","datePublished":"2026-03-21T03:26:59.781Z","dateUpdated":"2026-04-08T17:16:26.184Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-01-20T21:58:43.839Z"},"containers":{"cna":{"title":"Multi Post Carousel by Category <= 1.4 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'slides' Shortcode Attribute","descriptions":[{"lang":"en","value":"The Multi Post Carousel by Category plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'slides' shortcode attribute in all versions up to, and including, 1.4.
