{"id":"CVE-2026-3996","state":"PUBLISHED","title":"WP Games Embed <= 0.1beta - Authenticated (Contributor+) Stored Cross-Site Scripting via Shortcode Attributes","description":"The WP Games Embed plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the [game] shortcode in all versions up to and including 0.1beta. This is due to insufficient input sanitization and output escaping on user-supplied shortcode attributes such as 'width', 'height', 'src', 'title', 'description', 'game_url', 'main', and 'thumb', which are all directly concatenated into HTML output without any 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.","publishedAt":"2026-03-21T03:26:49.724Z","updatedAt":"2026-04-08T16:58:51.963Z","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":["sammyb WP Games Embed"],"affected":[{"vendor":"sammyb","product":"WP Games Embed","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"0.1beta","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/6a8cc968-01a5-45b8-bee8-86c858f86514?source=cve","https://plugins.trac.wordpress.org/browser/wp-games-embed/trunk/wp-games-embed.php#L41","https://plugins.trac.wordpress.org/browser/wp-games-embed/tags/0.1/wp-games-embed.php#L41","https://plugins.trac.wordpress.org/browser/wp-games-embed/trunk/wp-games-embed.php#L32","https://plugins.trac.wordpress.org/browser/wp-games-embed/tags/0.1/wp-games-embed.php#L32","https://plugins.trac.wordpress.org/browser/wp-games-embed/trunk/wp-games-embed.php#L35","https://plugins.trac.wordpress.org/browser/wp-games-embed/tags/0.1/wp-games-embed.php#L35","https://plugins.trac.wordpress.org/browser/wp-games-embed/trunk/wp-games-embed.php#L14","https://plugins.trac.wordpress.org/browser/wp-games-embed/tags/0.1/wp-games-embed.php#L14"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:11:50.837Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/3xxx/CVE-2026-3996.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-3996","state":"PUBLISHED","datePublished":"2026-03-21T03:26:49.724Z","dateUpdated":"2026-04-08T16:58:51.963Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-03-11T17:05:27.131Z"},"containers":{"cna":{"title":"WP Games Embed <= 0.1beta - Authenticated (Contributor+) Stored Cross-Site Scripting via Shortcode Attributes","descriptions":[{"lang":"en","value":"The WP Games Embed plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the [game] shortcode in all versions up to and including 0.1beta.
