What is CVE-2026-14225?

The Easy Appointments WordPress plugin, up to version 3.12.26, is affected by a flaw in its handling of shortcode input. This vulnerability arises from insufficient validation during a block-rendering process, where the plugin only checks the first tag of a supplied string against a predefined allowlist but fails to validate the entire string properly. This oversight allows users with contributor-level access to execute arbitrary registered shortcodes, potentially leading to unauthorized actions and compromising the security of the site.

Affected Version(s)

Easy Appointments 0 <= 3.12.26

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
