{"id":"CVE-2026-12136","state":"PUBLISHED","title":"SysBasics Customize My Account for WooCommerce <= 4.3.6 - Authenticated (Contributor+) Stored Cross-Site Scripting via Shortcode Attributes","description":"The Customize My Account For Woocommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'sysbasics_user_avatar' shortcode in versions up to, and including, 4.3.6. This is due to insufficient input sanitization and output escaping on user supplied attributes (min_height, min_width, max_height, max_width) in the wcmamtx_get_avatar_default() function, which are concatenated unescaped into the get_avatar() extra_attr style attribute. 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":"2026-06-18T06:50:04.743Z","updatedAt":"2026-06-18T12:31:19.266Z","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":["phppoet SysBasics Customize My Account for WooCommerce – Dashboard, Endpoints, Avatar & Menu Manager"],"affected":[{"vendor":"phppoet","product":"SysBasics Customize My Account for WooCommerce – Dashboard, Endpoints, Avatar & Menu Manager","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"4.3.6","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/44d041ca-caa6-410d-b2d1-7a63208cc512?source=cve","https://plugins.trac.wordpress.org/browser/customize-my-account-for-woocommerce/tags/4.3.6/include/wcmamtx_extra_functions.php#L163","https://plugins.trac.wordpress.org/browser/customize-my-account-for-woocommerce/tags/4.3.6/include/sysbasics-avatar-upload.php#L524","https://plugins.trac.wordpress.org/browser/customize-my-account-for-woocommerce/tags/4.3.6/include/sysbasics-avatar-upload.php#L573","https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&old=3571110%40customize-my-account-for-woocommerce&new=3571110%40customize-my-account-for-woocommerce&sfp_email=&sfph_mail="],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:10:52.580Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/12xxx/CVE-2026-12136.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-12136","state":"PUBLISHED","datePublished":"2026-06-18T06:50:04.743Z","dateUpdated":"2026-06-18T12:31:19.266Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-06-12T16:46:25.607Z"},"containers":{"cna":{"title":"SysBasics Customize My Account for WooCommerce <= 4.3.6 - Authenticated (Contributor+) Stored Cross-Site Scripting via Shortcode Attributes","descriptions":[{"lang":"en","value":"The Customize My Account For Woocommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'sysbasics_user_avatar' shortcode in versions up to, and including, 4.3.6.
