Exploitation Probability (EPSS)

Low risk
0.26%

18th percentile - higher than 18% of all known CVEs

Summary

The SMS Alert WordPress plugin before version 3.9.8 does not bind its 'mobile verified' session flag to the phone number that was actually verified. After an attacker verifies an OTP sent to their own phone, the signup/login handler reads a fresh, attacker-supplied phone number to select the account and logs them in. An unauthenticated attacker can therefore log in as any user, including an administrator, who has a billing phone on file.

Risk Assessment

The organization risks complete account takeover of administrators and other users, potentially leading to full site compromise.

Recommendation

Immediately update the SMS Alert plugin to version 3.9.8 or later.
