This month

HIGH 7.5REMOTE

CVE-2026-72582 is a high-severity flaw (CVSS 7.5) affecting affected software. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

A NULL pointer dereference vulnerability in fastschema through v0.15.1 allows an unauthenticated remote attacker to crash the server process with a single HTTP request. The sendOTPEmail function in pkg/auth/local.go dereferences a pointer obtained from an unchecked error path without validating it is non-nil, causing a fatal panic that terminates the entire server when a recovery request is sent to the /api/auth/local/recover endpoint.

Why this priority

High severity
Remotely exploitable, no login, no user action
