Arconix Shortcodes can let attackers add malicious scripts

CVE-2025-49858 · published 1 year ago
Summary

The Arconix Shortcodes plugin (versions up to 2.1.17) does not properly clean user-supplied content, allowing a stored cross‑site scripting attack. An attacker who can add or edit a shortcode could insert code that runs in the browsers of anyone who views the affected page, potentially stealing data or hijacking sessions. Update the plugin to a version that fixes the issue or replace it with a secure alternative, and ensure any existing shortcodes are reviewed for unwanted code.
