CVE-2026-14225: CWE-20 Improper Input Validation in Easy Appointments
Easy Appointments WordPress plugin versions through 3.12.26 contain an input validation vulnerability in shortcode processing. The plugin only validates the first tag of a shortcode string against an allowlist but renders the entire string, allowing users with contributor-level access to execute arbitrary registered shortcodes. The vulnerability has a low CVSS score of 2.7 and does not appear to have known exploits in the wild.
AI Analysis
Technical Summary
CVE-2026-14225 describes an improper input validation vulnerability (CWE-20) in the Easy Appointments WordPress plugin up to version 3.12.26. The flaw occurs in one of the block-rendering actions where the plugin validates only the first tag of the supplied shortcode string against an allowlist but proceeds to render the entire string. This allows users with contributor-level privileges to execute arbitrary registered shortcodes, potentially leading to limited unauthorized actions within the WordPress environment. The CVSS 3.1 base score is 2.7, reflecting low impact primarily on confidentiality with no integrity or availability impact. No official remediation or patch information is provided, and no known exploits are reported.
Potential Impact
The vulnerability allows contributor-level users to execute arbitrary registered shortcodes due to insufficient input validation. This could lead to limited unauthorized actions or information disclosure within the WordPress site context. The impact is limited as it requires contributor-level access and does not affect integrity or availability.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict contributor-level access carefully and monitor for unusual shortcode usage. Avoid granting contributor privileges to untrusted users.
