CVE-2025-30206
CRITICALCVE-2025-30206 is a critical-severity (CVSS 9.8) CWE-321 vulnerability in github.com/donknap/dpanel. O3 Security confirms whether CVE-2025-30206 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Dpanel's hard-coded JWT secret leads to remote code execution

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.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/donknap/dpanel. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update github.com/donknap/dpanel to 1.6.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-30206 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether CVE-2025-30206 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2025-30206. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
