CVE-2026-119597
OpenDeepWiki through 2.0.6 contains a hard-coded JWT signing key vulnerability that allows unauthenticated attackers to forge administrator tokens using the publicly known Jwt:SecretKey in appsettings.json.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.37%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
