What is CVE-2026-62253?
CVE-2026-62253 is a critical authentication bypass vulnerability in sipcapture homer, published on 7 Oct 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
Homer is open source telecom observability software. Prior to version 11.0.283, both JWT middleware functions (`JWTMiddleware` and `JWTMiddlewareV4`) immediately return `next(c)` when `jwtSecret == ""`. The JWT secret defaults to an empty string. On a default installation, all protected API endpoints under `/api/v1`, `/api/v3`, and `/api/v4` are completely unauthenticated. Version 11.0.283 patches the issue.
