The WP Shortcodes Plugin — Shortcodes Ultimate plugin for WordPress suffers from a stored cross-site scripting vulnerability (CWE-79) due to improper neutralization of input during web page generation. Authenticated attackers with Contributor-level privileges or higher can inject arbitrary web scripts via multiple parameters, which are then stored and executed when any user accesses the compromised page. This vulnerability affects all versions up to and including 7.2.2. The CVSS 3.1 base score is 5.4, reflecting network attack vector, low attack complexity, required privileges at the contributor level, user interaction required, scope change, and low impact on confidentiality and integrity but no impact on availability. No patch or official remediation guidance has been published yet.

An attacker with Contributor-level access or higher can inject persistent malicious scripts into pages via the vulnerable plugin parameters. These scripts execute in the context of users who view the infected pages, potentially leading to theft of user credentials, session hijacking, or other malicious actions limited to the scope of the injected script. The impact is limited to confidentiality and integrity with no direct availability impact. There are no known active exploits reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict Contributor-level access to trusted users only and consider disabling or removing the WP Shortcodes Plugin — Shortcodes Ultimate if feasible. Monitor for plugin updates from the vendor and apply them promptly once available.
