No CVSS score has been assigned to CVE-2025-53534 yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by CVE-2025-53534?

CVE-2025-53534 affects the following packages: github.com/tnborg/panel (Go), github.com/tnborg/panel (Go). Ecosystems affected: Go.

How do I fix CVE-2025-53534?

Update github.com/tnborg/panel to 2.5.6 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-53534 is resolved across your whole dependency graph.

How do I detect CVE-2025-53534 in my Go dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/tnborg/panel. 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.

How do I mitigate CVE-2025-53534 if there is no patch (or I can't update yet)?

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 does O3 Security protect against CVE-2025-53534?

O3 pinpoints whether CVE-2025-53534 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is CVE-2025-53534 actively exploited in the wild?

No public exploit code has been indexed for CVE-2025-53534 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for CVE-2025-53534?

CVE-2025-53534 has an EPSS (Exploit Prediction Scoring System) score of 0.6%, placing it in the 44th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

When was CVE-2025-53534 published, and has it been updated?

CVE-2025-53534 was published on August 5, 2025 and was last updated on April 2, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

RatPanel is a server operation and maintenance management panel. In versions 2.3.19 through 2.5.5, when an attacker obtains the backend login path of RatPanel (including but not limited to weak default paths, brute-force cracking, etc.), they can execute system commands or take over hosts managed by the panel without logging in. In addition to this remote code execution (RCE) vulnerability, the flawed code also leads to unauthorized access. RatPanel uses the CleanPath middleware provided by github.com/go-chi/chi package to clean URLs, but but the middleware does not process r.URL.Path, which can cause the paths to be misinterpreted. This is fixed in version 2.5.6.
