SMS Alert 4.0.0 - Unauthenticated Authentication Bypass via Login with OTP

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

The SMS Alert WordPress plugin before 4.0.1 does not verify that the account being logged in is the one the verified one-time code belongs to, allowing unauthenticated attackers to sign in as any user with a stored phone number, including an administrator, by completing a code challenge on a phone they control.
