CVE-2026-19856

All in One SEO < 5.0.2.1 - Unauthenticated Arbitrary Shortcode Execution via Search Query

Description

The All in One SEO WordPress plugin before 5.0.2.1 does not correctly determine which shortcodes are present in content derived from user input before deciding which ones to strip, allowing unauthenticated users to execute arbitrary shortcodes registered on the site. On sites upgraded from older versions the protection is disabled outright, making the issue reachable without any crafted input.
