WPFunnels creates accounts while registration is disabled
WPFunnels versions 3.6.3 through 3.12.13 trust a request value rather than WordPress's registration setting in two opt-in registration paths. An unauthenticated attacker can create WordPress accounts even when site registration is disabled; this is an incomplete fix for CVE-2025-12353.

3.13.0- Published
- Sep 04, 2026
This CVE was published Sep 04, 2026 and is one of 23 known issues for this plugin.
Update, patch or deactivate.
Update to 3.13.0 or later and audit accounts created through WPFunnels opt-in forms while registration was disabled.
A safe version is available, so updating to that version or later is the preferred remediation. If an immediate update is not practical, consider a targeted application patch or temporarily restricting the affected functionality.
Deactivate only when warranted by your risk profile, or when advised by your hosting provider in the limited circumstances where the vulnerability cannot otherwise be mitigated. If you’re unsure which action is appropriate, contact Fused or your hosting provider for guidance.
Technical description
The WPFunnels WordPress plugin before 3.13.0 does not check whether user registration is enabled on the site before creating accounts from opt-in form submissions, relying on a value supplied in the request instead, allowing unauthenticated attackers to create WordPress user accounts even when registration is disabled. This is an incomplete fix for CVE-2025-12353: the check added in 3.6.3 covers only one of the three registration paths.
