dpanel: Use of Hard-coded Cryptographic Key

CVE-2025-30206 is a critical-severity use of hard-coded cryptographic key vulnerability in dpanel from Donknap, 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 dpanel versions: < 1.6.1. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.9% chance of exploitation within 30 days, higher than 60% of scored CVEs.

Patch this week

Critical severity: a successful attack would have severe impact.

What to do

  1. Check which version of dpanel you run against the affected versions below, and install the vendor's latest release.
  2. Read the advisory on github.com for workarounds and exact fixed builds.
  3. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description

Dpanel is a Docker visualization panel system which provides complete Docker management functions. The Dpanel service contains a hardcoded JWT secret in its default configuration, allowing attackers to generate valid JWT tokens and compromise the host machine. This security flaw allows attackers to analyze the source code, discover the embedded secret, and craft legitimate JWT tokens. By forging these tokens, an attacker can successfully bypass authentication mechanisms, impersonate privileged users, and gain unauthorized administrative access. Consequently, this enables full control over the host machine, potentially leading to severe consequences such as sensitive data exposure, unauthorized command execution, privilege escalation, or further lateral movement within the network environment. This issue is patched in version 1.6.1. A workaround for this vulnerability involves replacing the hardcoded secret with a securely generated value and load it from secure configuration storage.
