CVE-2026-14225: CWE-20 Improper Input Validation in Easy Appointments
The Easy Appointments WordPress plugin before 3.12.28 does not correctly validate shortcode input in one of its block-rendering actions, checking only the first tag of the supplied string against an allowlist while rendering the entire string, allowing users with contributor-level access to execute arbitrary registered shortcodes.
AI Analysis
Technical Summary
The Easy Appointments WordPress plugin versions prior to 3.12.28 contain an input validation vulnerability (CWE-20) in one of its block-rendering actions. The plugin validates only the first tag of the supplied shortcode string against an allowlist but proceeds to render the entire string. This improper validation enables users with contributor-level privileges to execute arbitrary registered shortcodes, potentially leading to unintended shortcode execution within the WordPress environment.
Potential Impact
The vulnerability allows users with contributor-level access to execute arbitrary registered shortcodes. The CVSS score of 2.7 indicates low impact, with limited confidentiality impact and no integrity or availability impact. Exploitation requires authenticated contributor-level privileges, reducing the overall risk.
Mitigation Recommendations
No official patch or remediation guidance is currently available. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is released, restrict contributor-level access to trusted users and monitor for unusual shortcode usage.
