A NULL pointer dereference vulnerability exists in fastschema through version 0.15.1. An unauthenticated remote attacker can send a specially crafted HTTP request to the /api/auth/local/recover endpoint, triggering a fatal panic in the sendOTPEmail function. This causes the server process to crash, resulting in a denial of service condition.
AI Analysis
Technical Summary
The vulnerability (CVE-2026-72582) in fastschema up to version 0.15.1 is due to the sendOTPEmail function in pkg/auth/local.go dereferencing a pointer obtained from an unchecked error path without verifying it is non-nil. When a recovery request is sent to the /api/auth/local/recover endpoint, this leads to a NULL pointer dereference and a fatal panic that terminates the entire server process. This allows an unauthenticated remote attacker to crash the server with a single HTTP request, causing denial of service.
Potential Impact
The impact is a denial of service (DoS) condition caused by server process termination. There is no confidentiality or integrity impact reported. The vulnerability can be exploited remotely without authentication.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, consider restricting access to the /api/auth/local/recover endpoint or implementing network-level protections to mitigate exploitation risk.
