CVE-2026-94421 andy_moyle CVE debrief
The Church Admin plugin for WordPress has a Stored Cross-Site Scripting vulnerability via the 'email' parameter in versions up to and including 5.1.2. This allows authenticated attackers with subscriber-level access and above to inject arbitrary web scripts, which execute when a user accesses an injected page. The vulnerability is due to insufficient input sanitization and output escaping. Defenders should assess exposure and prioritize verification and remediation, focusing on WordPress installations with subscriber-level access and above.

Who should care
Defenders responsible for WordPress installations with the Church Admin plugin, particularly those with subscriber-level access and above, should assess exposure and prioritize verification and remediation.
Why it matters
The Church Admin plugin for WordPress has a Stored Cross-Site Scripting vulnerability, allowing authenticated attackers to inject arbitrary web scripts, which can lead to security risks for WordPress installations with subscriber-level access and above.
- Authenticated attackers with subscriber-level access can inject arbitrary web scripts
- Injected scripts execute when a user accesses an injected page
- Defenders must verify exposure of Church Admin plugin versions up to 5.1.2
- Remediation requires updating to a fixed version of the Church Admin plugin
Technical summary
The Church Admin plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'email' parameter in all versions up to, and including, 5.1.2 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
Defensive priority
Defenders should prioritize verifying exposure of Church Admin plugin versions up to 5.1.2, assessing subscriber-level access and above, and reviewing user input sanitization and output escaping for the 'email' parameter.
Recommended defensive actions
- Verify Church Admin plugin version and update to a fixed version if necessary
- Assess subscriber-level access and above for potential exploitation
- Review user input sanitization and output escaping for the 'email' parameter
- Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
- 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
- Track exceptions, retest remediated assets, and close the item only after evidence is documented
