What is CVE-2026-62253?

Homer, an open-source telecom observability software, has a significant vulnerability in its JWT middleware functions. In versions before 11.0.283, the software allows unauthenticated access to various protected API endpoints due to a misconfiguration where the JWT secret is set to an empty string by default. This flaw exposes endpoints under /api/v1, /api/v3, and /api/v4, potentially leading to unauthorized operations. The release of version 11.0.283 addresses this issue by implementing necessary security measures.
