OpenDeepWiki: Use of Hard-coded Cryptographic Key
CVE-2026-119597 is a critical-severity use of hard-coded cryptographic key vulnerability in OpenDeepWiki from AIDotNet, with a CVSS 3.1 base score of 9.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected OpenDeepWiki versions: 2.0.6 and earlier. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.37% chance of exploitation within 30 days, which is low compared with other CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Check which version of OpenDeepWiki you run against the affected versions below, and install the vendor's latest release.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

| Vendor | Product | Affected versions | Fixed in |
|---|---|---|---|
| AIDotNet | OpenDeepWiki | 2.0.6 and earlier | Not stated |

Official description
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. Attackers can mint HS256 bearer tokens with an Admin role claim to access /api/admin endpoints and control users, roles, repositories, settings, and API keys.
