CVE-2025-50739 is a critical-severity Code Injection (CWE-94) vulnerability in Omnitools (inferred from references). Its CVSS base score is 9.8 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 23.4% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).
Deeper analysis
CVE-2025-50739 affects iib0011 omni-tools version 0.4.0, enabling remote code execution through unsafe JSON deserialization. This vulnerability, associated with CWE-94 (code injection), was published on 2025-10-30 and carries a CVSS v3.1 base score of 9.8, indicating critical severity due to its network accessibility, low attack complexity, lack of required privileges or user interaction, and high impact on confidentiality, integrity, and availability.
An unauthenticated attacker with network access can exploit this flaw remotely with low complexity and no user interaction, achieving full remote code execution on the affected system. The CVSS vector (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) underscores the ease of exploitation, allowing arbitrary code execution that compromises the entire host.
