{"id":"CVE-2026-15604","state":"PUBLISHED","title":"Toocheke Companion <= 2.10 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'series_bg_color' Post Meta","description":"The Toocheke Companion plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 2.10 via the 'series_bg_color' post meta field. This is due to insufficient input sanitization in the toocheke_series_bg_color_save() function (which stores the raw $_POST value in post meta) and insufficient output escaping in the series admin column rendering (where the stored value is concatenated into a style attribute without esc_attr()). 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, such as an administrator, accesses the series list table in the admin dashboard.","publishedAt":"2026-08-16T05:27:27.151Z","updatedAt":"2026-08-18T19:38:03.065Z","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":["toocheke Toocheke Companion"],"affected":[{"vendor":"toocheke","product":"Toocheke Companion","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"2.10","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/1bf78bc1-55d7-4230-913f-d7c521225367?source=cve","https://plugins.trac.wordpress.org/browser/toocheke-companion/tags/2.3/inc/class-toocheke-companion-admin-columns.php#L296","https://plugins.trac.wordpress.org/browser/toocheke-companion/tags/2.3/inc/class-toocheke-companion-metaboxes.php#L959","https://plugins.trac.wordpress.org/browser/toocheke-companion/tags/2.3/inc/class-toocheke-companion-metaboxes.php#L960","https://plugins.trac.wordpress.org/browser/toocheke-companion/tags/2.11/inc/class-toocheke-companion-admin-columns.php#L296"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:11:00.674Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/15xxx/CVE-2026-15604.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-15604","state":"PUBLISHED","datePublished":"2026-08-16T05:27:27.151Z","dateUpdated":"2026-08-18T19:38:03.065Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-07-13T15:29:55.750Z"},"containers":{"cna":{"title":"Toocheke Companion <= 2.10 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'series_bg_color' Post Meta","descriptions":[{"lang":"en","value":"The Toocheke Companion plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 2.10 via the 'series_bg_color' post meta field.
