CVE-2026-7441 describes a stored cross-site scripting vulnerability in the Simple Yearly Archive plugin for WordPress. The flaw exists in all versions up to and including 2.2.4, where the posttype attribute of the SimpleYearlyArchive shortcode does not properly sanitize or escape input. This allows authenticated attackers with Contributor-level privileges or above to inject arbitrary JavaScript code that executes in the context of users visiting the injected pages. The vulnerability has a CVSS 3.1 base score of 6.4, indicating medium severity, with network attack vector, low attack complexity, and no user interaction required.

An attacker with Contributor-level or higher privileges can inject persistent malicious scripts into pages via the vulnerable shortcode attribute. These scripts execute in the browsers of users who view the affected pages, potentially leading to information disclosure or session hijacking. The vulnerability does not affect availability and requires authenticated access, limiting the attack scope.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict Contributor-level access to trusted users only and consider disabling or removing the Simple Yearly Archive plugin if possible. Monitor vendor channels for updates and apply patches promptly once released.
