{"id":"CVE-2026-1395","state":"PUBLISHED","title":"Gutentools <= 1.1.3 - Authenticated (Contributor+) Stored Cross-Site Scripting via Post Slider Block Attributes","description":"The Gutentools plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Post Slider block's block_id attribute in all versions up to, and including, 1.1.3. This is due to insufficient input sanitization and output escaping combined with a custom unescaping routine that reintroduces dangerous characters. 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":"2026-04-22T09:27:20.476Z","updatedAt":"2026-04-22T12:05:44.174Z","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":["gutentools Gutentools"],"affected":[{"vendor":"gutentools","product":"Gutentools","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.1.3","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/b2683b4e-b993-4c84-b7cc-a2cb511b4097?source=cve","https://plugins.trac.wordpress.org/browser/gutentools/trunk/core/blocks/post-slider.php#L232","https://plugins.trac.wordpress.org/browser/gutentools/tags/1.1.3/core/blocks/post-slider.php#L232","https://plugins.trac.wordpress.org/browser/gutentools/trunk/core/gutentools_block.php#L123","https://plugins.trac.wordpress.org/changeset/3476597/gutentools/trunk/core/blocks/post-slider.php"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:11:10.572Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/1xxx/CVE-2026-1395.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-1395","state":"PUBLISHED","datePublished":"2026-04-22T09:27:20.476Z","dateUpdated":"2026-04-22T12:05:44.174Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-01-23T21:14:51.848Z"},"containers":{"cna":{"title":"Gutentools <= 1.1.3 - Authenticated (Contributor+) Stored Cross-Site Scripting via Post Slider Block Attributes","descriptions":[{"lang":"en","value":"The Gutentools plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Post Slider block's block_id attribute in all versions up to, and including, 1.1.3.
