{"id":"CVE-2026-8896","state":"PUBLISHED","title":"MIR blocks and shortcodes <= 1.0.0 - Authenticated (Contributor+) Stored Cross-Site Scripting via Shortcode Attributes","description":"The MIR blocks and shortcodes plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'title' attribute (and other attributes such as 'ready_animation_text') of the 'msc_stats' shortcode in versions up to, and including, 1.0.0. This is due to insufficient input sanitization and output escaping on user supplied shortcode attributes inside the msc_stats() rendering 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":"2026-06-24T05:33:30.909Z","updatedAt":"2026-06-30T03:19:58.835Z","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":["mirsoftware MIR blocks and shortcodes"],"affected":[{"vendor":"mirsoftware","product":"MIR blocks and shortcodes","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.0.0","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/d7d698be-fae6-4960-912a-1078ea407031?source=cve","https://plugins.trac.wordpress.org/browser/mir-blocks-and-shortcodes/trunk/frontend-templates/function/msc-stats.php#L44","https://plugins.trac.wordpress.org/browser/mir-blocks-and-shortcodes/trunk/frontend-templates/function/msc-stats.php#L22"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:13:26.108Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/8xxx/CVE-2026-8896.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-8896","state":"PUBLISHED","datePublished":"2026-06-24T05:33:30.909Z","dateUpdated":"2026-06-30T03:19:58.835Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-05-18T21:03:56.264Z"},"containers":{"cna":{"title":"MIR blocks and shortcodes <= 1.0.0 - Authenticated (Contributor+) Stored Cross-Site Scripting via Shortcode Attributes","descriptions":[{"lang":"en","value":"The MIR blocks and shortcodes plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'title' attribute (and other attributes such as 'ready_animation_text') of the 'msc_stats' shortcode in versions up to, and including, 1.0.0.
