CVE-2026-13741 UnitedOver CVE debrief

Who should care

Users of the Digits: WordPress Mobile Number Signup and Login plugin for WordPress, particularly those with Subscriber-level access and above, should be aware of this vulnerability and take steps to mitigate it. This includes administrators who have configured the built-in DIGITS User Role field and operators who may be impacted by potential privilege escalation.

Technical summary

The vulnerability is caused by missing authorization and role validation in the `dig_update_wpwc_custom_fields()` function. This allows authenticated attackers with Subscriber-level access and above to escalate their privileges to Administrator by submitting a forged `digits_reg_userrole` value during profile update. The affected product is the Digits: WordPress Mobile Number Signup and Login plugin for WordPress, in all versions up to, and including, 9.1.0.5.
