CVE-2026-15604: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in toocheke Toocheke Companion
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.
AI Analysis
Technical Summary
CVE-2026-15604 is a stored cross-site scripting vulnerability in the Toocheke Companion WordPress plugin affecting versions up to 2.10. The vulnerability is due to insufficient sanitization in the toocheke_series_bg_color_save() function, which stores raw $_POST data in post meta, and insufficient escaping when rendering the series admin column where the stored value is concatenated into a style attribute without using esc_attr(). Authenticated attackers with contributor-level privileges or higher can exploit this to inject arbitrary JavaScript that executes in the context of the WordPress admin dashboard when an administrator views the series list table.
Potential Impact
An attacker with contributor-level access or higher can inject malicious scripts that execute in the administrator's browser when viewing the series list table. This can lead to theft of administrative session tokens, unauthorized actions in the admin interface, or other client-side impacts. The vulnerability does not affect availability but impacts confidentiality and integrity within the WordPress admin context.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict contributor-level access and above to trusted users only. Monitor for updates from the Toocheke plugin vendor and apply official patches once released.
