Summary

CVE-2025-28386 is a critical-severity Code Injection (CWE-94) vulnerability in Openc3 Cosmos. Its CVSS base score is 9.8 (Critical).

Operationally, ranked in the top 11.2% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

Deeper analysis

A remote code execution vulnerability tracked as CVE-2025-28386 affects the Plugin Management component of OpenC3 COSMOS version 6.0.0. The flaw, assigned CWE-94, permits an attacker to upload a specially crafted .txt file that results in arbitrary code execution on the server. It carries a CVSS 3.1 base score of 9.8, reflecting network-accessible attack vector, low complexity, and no required privileges or user interaction.

Unauthenticated remote attackers can exploit the issue by sending a malicious file through the plugin upload functionality, achieving full confidentiality, integrity, and availability impact on the affected COSMOS instance. Successful exploitation grants the ability to run attacker-controlled code within the application environment, potentially leading to complete system compromise.

Public references point to the OpenC3 project site and a detailed security assessment report that identified the weakness during testing of the open-source mission framework; however, the provided sources do not describe specific patches or mitigation steps. The associated EPSS score remains flat at 0.0404 with no observed increase since disclosure.
