{"id":"CVE-2025-11828","state":"PUBLISHED","title":"Magazine Companion <= 1.2.3 - Authenticated (Contributor+) Stored Cross-Site Scripting","description":"The Magazine Companion plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'headerHtmlTag' attribute in the bnm-blocks/featured-posts-1 block in all versions up to, and including, 1.2.3. This is due to insufficient input sanitization and output escaping when using user-supplied values as HTML tag names. 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":"2025-11-11T03:30:44.964Z","updatedAt":"2026-04-08T17:06:37.008Z","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":["pubudu-malalasekara Post Blocks & Tools"],"affected":[{"vendor":"pubudu-malalasekara","product":"Post Blocks & Tools","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.2.3","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/8fa2e98b-5054-46fd-b22e-eac59b581a3c?source=cve","https://wordpress.org/plugins/bnm-blocks","https://plugins.trac.wordpress.org/browser/bnm-blocks/tags/1.2.3/src/blocks/posts/featured-posts-1/view.php#L34","https://plugins.trac.wordpress.org/changeset/3392064/"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:08:31.050Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2025/11xxx/CVE-2025-11828.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2025-11828","state":"PUBLISHED","datePublished":"2025-11-11T03:30:44.964Z","dateUpdated":"2026-04-08T17:06:37.008Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2025-10-15T18:51:23.266Z"},"containers":{"cna":{"title":"Magazine Companion <= 1.2.3 - Authenticated (Contributor+) Stored Cross-Site Scripting","descriptions":[{"lang":"en","value":"The Magazine Companion plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'headerHtmlTag' attribute in the bnm-blocks/featured-posts-1 block in all versions up to, and including, 1.2.3.
