CVE-2026-62253: Sipcapture Homer

Critical severity, CVSS 9.8. EPSS: 0.4% chance of exploitation in the next 30 days.

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.

Affected products

• Sipcapture Homer: before 11.0.283 (fixed in 11.0.283)
