CVE-2026-13741
The Digits: WordPress Mobile Number Signup and Login plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 9.1.0.5. This is due to missing authorization and role validation in the `dig_update_wpwc_custom_fields()` function. This makes it possible for 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, granted the site administrator has configured the built-in DIGITS User Role field.
No public exploitation has been reported so far. No distribution fix is listed yet; apply vendor mitigations and monitor.
Recommended action: Track your distribution's security tracker and apply the fix as soon as it ships.

Affected & fixed versions by distribution
Versions are the native distribution strings (backport-aware): RHEL/Debian/SUSE backport fixes, so compare with the distro version comparator (dpkg / rpm / vercmp), not the upstream version.
No affected package in the tracked watchlist yet (Debian, Ubuntu, Arch, SUSE, Red Hat...). Triage may still be pending.
