AI Analysis

Impact

The vulnerability stems from improper neutralization of input during web page generation, enabling a DOM‑based XSS flaw. An attacker can inject malicious scripts that run in a victim’s browser, potentially stealing session cookies, defacing content, or executing further client‑side attacks.

Affected Systems

The affected product is WordPress Penci Shortcodes & Performance by PenciDesign, versions up to and including 6.1. Any installation of the plugin at these versions is vulnerable.

Risk and Exploitability

The CVSS score of 6.5 indicates a moderate risk, while the predicted probability of exploitation is very low. The flaw is not part of the CISA KEV list. Exploitation requires a user to visit a page served by an affected instance of the plugin, after which the attacker can inject arbitrary JavaScript. The attack vector is client‑side through the plugin’s shortcode handling (inferred from the description).

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Upgrade the Penci Shortcodes & Performance plugin to version 6.2 or later.
  • If an upgrade is not immediately possible, deactivate or remove the plugin and then consider purging all shortcodes that might have been injected.
  • Apply a CMS security plugin or server‑side input sanitization to guard against unexpected script injection as a temporary workaround.
