{"id":"CVE-2026-16090","state":"PUBLISHED","title":"GamiPress <= 7.9.9.1 - Authenticated (Contributor+) Stored Cross-Site Scripting via gamipress_achievement Shortcode","description":"The GamiPress – Gamification plugin to reward points, achievements, badges & ranks in WordPress plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'heading_size' Shortcode Attribute in 'gamipress_achievement' in all versions up to, and including, 7.9.9.1 due to insufficient input sanitization and output escaping. 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. WordPress save-time wp_kses_post does not neutralize this payload because the injected value is stored inside a shortcode attribute rather than as a raw HTML tag, and is only emitted into HTML at render time without escaping.","publishedAt":"2026-08-01T07:49:48.357Z","updatedAt":"2026-08-03T17:36:05.600Z","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":["rubengc GamiPress – Gamification plugin to reward points, achievements, badges & ranks in WordPress"],"affected":[{"vendor":"rubengc","product":"GamiPress – Gamification plugin to reward points, achievements, badges & ranks in WordPress","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"7.9.9.1","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/77727d02-796b-4c5b-ad5d-d1c366760abc?source=cve","https://plugins.trac.wordpress.org/browser/gamipress/tags/7.9.9/includes/filters.php#L542","https://plugins.trac.wordpress.org/browser/gamipress/tags/7.9.9/includes/shortcodes/gamipress_achievement.php#L229","https://plugins.trac.wordpress.org/changeset?reponame=&old=3619577%40gamipress&new=3619577%40gamipress"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:11:00.674Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/16xxx/CVE-2026-16090.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-16090","state":"PUBLISHED","datePublished":"2026-08-01T07:49:48.357Z","dateUpdated":"2026-08-03T17:36:05.600Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-07-17T14:05:35.669Z"},"containers":{"cna":{"title":"GamiPress <= 7.9.9.1 - Authenticated (Contributor+) Stored Cross-Site Scripting via gamipress_achievement Shortcode","descriptions":[{"lang":"en","value":"The GamiPress – Gamification plugin to reward points, achievements, badges & ranks in WordPress plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'heading_size' Shortcode Attribute in 'gamipress_achievement' in all versions up to, and including, 7.9.9.1 due to insufficient input sanitization and output escaping.
