Published: 26 February 2022
Summary
CVE-2022-26149 is a high-severity Unrestricted Upload of File with Dangerous Type (CWE-434) vulnerability in Modx Revolution. Its CVSS base score is 7.2 (High).
Operationally, ranked in the top 6.6% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
MODX Revolution through version 2.8.3-pl contains an unrestricted file upload vulnerability tracked as CVE-2022-26149 and CWE-434. The flaw stems from the ability of authenticated administrators to modify the Uploadable File Types configuration setting, which permits the upload of executable files that can subsequently be executed on the server.
An attacker with administrative credentials can exploit the issue remotely over the network without user interaction. Successful exploitation grants arbitrary code execution with full impact on confidentiality, integrity, and availability, corresponding to the CVSS 7.2 rating.
Public proof-of-concept exploits have been published on Packet Storm and GitHub demonstrating remote code execution against the affected versions. The associated EPSS scores, with a current value of 0.1049 and a peak of 0.1415, reflect moderate and sustained exploitation interest following disclosure. No official patch or mitigation guidance appears among the referenced sources.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Requiring identifiable owners for portable devices reduces the attack surface for unrestricted uploads of dangerous file types via anonymous media.
Dangerous file uploads can be detonated in the chamber to determine malice before any production write or execution occurs.
Prevents unrestricted writing of arbitrary or malicious firmware by keeping hardware write-protect enabled except under tightly controlled manual procedures.
Scans files from external sources on download/open/execute, blocking unrestricted uploads of dangerous file types.
