CVE-2026-90945
Crawlab through 0.6.3 uses a hard-coded HMAC-SHA256 secret for JWT token signing that cannot be overridden via configuration or environment variables.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.53%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
Crawlab through 0.6.3 uses a hard-coded HMAC-SHA256 secret for JWT token signing that cannot be overridden via configuration or environment variables. Unauthenticated attackers can forge valid administrator tokens to access administrative APIs and execute code on worker nodes.
