Who should care

Defenders responsible for WordPress installations with the SMS Alert plugin, particularly those using versions 3.9.6 to 4.0.0, should assess exposure and prioritize verification and remediation.

Why it matters

CVE-2026-94257 is a critical vulnerability in the SMS Alert WordPress plugin that allows unauthenticated attackers to escalate privileges by resetting passwords on arbitrary accounts. Defenders should prioritize verifying exposure, applying compensating controls, and monitoring for suspicious activity.

• Defenders must verify exposure of SMS Alert versions 3.9.6 to 4.0.0 to prevent potential privilege escalation.
• Successful exploitation could allow attackers to gain administrative access to WordPress installations.
• Defenders should prioritize applying compensating controls to limit access to the SMS Alert plugin until a patch is verified.
• Verification of inventory and monitoring for suspicious activity related to password reset attempts are necessary.

Technical summary

The SMS Alert WordPress plugin before 4.0.1 does not bind the account whose password is being changed to the phone number that was actually verified during its OTP password reset. This allows unauthenticated attackers to set a new password on an arbitrary account, including administrators, by verifying a one-time code sent to a phone number they control. The vulnerability exists in versions 3.9.6 to 4.0.0 and allows for privilege escalation. Defenders should prioritize verifying exposure and applying compensating controls.
