CVE-2026-6725 is a stored cross-site scripting vulnerability in the WPC Smart Messages for WooCommerce WordPress plugin, specifically affecting the 'text' attribute of the wpcsm_text_rotator shortcode in all versions up to 4.2.8. The root cause is insufficient sanitization and escaping of user-supplied input, allowing authenticated users with contributor-level privileges or higher to inject arbitrary JavaScript code. This code executes in the context of any user who accesses the injected page, potentially leading to session hijacking or other script-based attacks. The vulnerability has a CVSS 3.1 base score of 6.4 (medium severity) with network attack vector, low attack complexity, and no user interaction required for exploitation once injected. No official fix or patch has been announced by the vendor as of the published date.

An authenticated attacker with contributor-level access or higher can inject malicious scripts into pages via the vulnerable shortcode attribute. These scripts execute in the browsers of users who visit the affected pages, potentially leading to theft of user credentials, session tokens, or other malicious actions within the context of the affected site. The impact is limited to confidentiality and integrity (partial), with no direct availability impact. No known exploits in the wild have been reported.

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