CVE-2026-14225 Easy Appointments CVE debrief
The Easy Appointments WordPress plugin through 3.12.26 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. This vulnerability has a CVSS score of 2.7 and LOW severity, indicating a relatively low risk but still requiring attention. Users of Easy Appointments WordPress plugin version 3.12.26 and prior should review their installations to ensure they are not exposed to potential exploitation. The CVE record and NVD entry provide further details, but additional verification may be necessary to confirm the scope of affected products and potential operational impact.

Who should care
Users of Easy Appointments WordPress plugin version 3.12.26 and prior, especially those with contributor-level access, should review and validate shortcode inputs to prevent potential exploitation. Additionally, operators, platform administrators, vulnerability management teams, and security teams should be aware of the potential risks and take necessary precautions to protect their environments.
Technical summary
The Easy Appointments WordPress plugin through 3.12.26 has a vulnerability allowing users with contributor-level access to execute arbitrary registered shortcodes due to insufficient validation of shortcode input in one of its block-rendering actions. This issue arises from the plugin's block-rendering mechanism, which checks only the first tag of the supplied string against an allowlist while rendering the entire string. As a result, an attacker with contributor-level access could potentially exploit this vulnerability to execute arbitrary shortcodes, potentially leading to unintended actions or data exposure. The vulnerability has a CVSS score of 2.7, indicating a low severity, but it is still essential for users of the affected plugin versions to review and validate shortcode inputs to prevent potential exploitation.
Defensive priority
Low-priority defensive review recommended due to limited CVSS score of 2.7 and lack of known exploit activity.
Recommended defensive actions
- Review and validate shortcode inputs in Easy Appointments WordPress plugin version 3.12.26 and prior.
- Restrict contributor-level access to sensitive block-rendering actions.
- Monitor for suspicious shortcode execution activity.
- Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up.
- Review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance.
- Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed.
- Check relevant monitoring, detection, and logs for exposed assets that need extra review.
Evidence notes
The evidence for this CVE is limited, primarily based on the official CVE record and NVD entry. The CVE record indicates a CVSS score of 2.7 and LOW severity. However, the scope of affected products, potential operational impact, and specific defensive measures are not detailed. Defenders should verify the accuracy of this information within their specific environments and review shortcode inputs to prevent potential exploitation.
