CVE-2025-53534 is a high-severity Authentication Bypass by Primary Weakness (CWE-305) vulnerability. Its CVSS base score is 7.7 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 47th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to IA-2 (Identification and Authentication (Organizational Users)) and IA-8 (Identification and Authentication (Non-organizational Users)) — see the control section below for these in your framework.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
RatPanel, a server operation and maintenance management panel, contains an authentication bypass vulnerability in versions 2.3.19 through 2.5.5. The flaw stems from improper use of the CleanPath middleware in the github.com/go-chi/chi package, which fails to sanitize r.URL.Path and allows path misinterpretation. This leads to remote code execution or full host takeover, along with broader unauthorized access, when an attacker reaches the backend login endpoint. The issue is tracked under CWE-305 and was corrected in version 2.5.6.
An attacker who first discovers or brute-forces the panel's backend login path can exploit the vulnerability without valid credentials. Successful exploitation grants the ability to run arbitrary system commands on the RatPanel host or seize control of any servers managed through the panel.
Public advisories and the associated patch release recommend immediate upgrade to RatPanel 2.5.6. The fix is detailed in the project commit ed5c74c and the GitHub Security Advisory GHSA-fm3m-jrgm-5ppg.
The EPSS score has remained flat at 0.0230 with no observed increase after disclosure.

Vulnerability Data
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.
