CVE-2025-50739 identifies a critical security vulnerability in iib0011 omni-tools version 0.4.0, specifically a remote code execution (RCE) flaw caused by unsafe JSON deserialization. The vulnerability is classified under CWE-94, indicating that the software improperly processes JSON input, allowing attackers to inject and execute arbitrary code remotely. The CVSS v3.1 base score of 9.8 reflects the severity, with an attack vector of network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), and no user interaction needed (UI:N). The vulnerability affects confidentiality, integrity, and availability (C:H/I:H/A:H) of impacted systems. Since the vulnerability is exploitable remotely without authentication or user interaction, it poses a significant risk to any exposed deployments of omni-tools. The lack of available patches or known exploits in the wild suggests this is a newly disclosed issue, requiring immediate attention. The tool’s use in automation and integration contexts means exploitation could lead to full system compromise, data breaches, or service disruption. The vulnerability was reserved in June 2025 and published in October 2025, indicating recent discovery and disclosure. Organizations relying on omni-tools should prioritize vulnerability assessment and containment strategies while awaiting official patches.

For European organizations, the impact of CVE-2025-50739 could be severe. Exploitation enables attackers to execute arbitrary code remotely, potentially leading to full system compromise, data theft, disruption of services, and lateral movement within networks. Sectors such as manufacturing, industrial automation, software development, and critical infrastructure that utilize omni-tools for integration or automation are particularly vulnerable. Confidentiality breaches could expose sensitive corporate or personal data, while integrity violations might corrupt critical operational processes. Availability impacts could cause downtime, affecting business continuity and potentially leading to financial losses and reputational damage. Given the vulnerability requires no authentication or user interaction, attackers can exploit it at scale, increasing the risk of widespread attacks. The absence of patches heightens the urgency for proactive defensive measures. European regulatory frameworks like GDPR also impose strict data protection requirements, so exploitation could result in legal and compliance consequences.

1. Immediately restrict network access to omni-tools instances by implementing strict firewall rules and network segmentation to limit exposure to untrusted networks. 2. Monitor logs and network traffic for unusual JSON payloads or suspicious activity indicative of exploitation attempts. 3. Employ application-layer filtering or web application firewalls (WAFs) capable of detecting and blocking malicious JSON deserialization patterns. 4. Conduct thorough asset inventories to identify all deployments of iib0011 omni-tools v0.4.0 within the organization. 5. Engage with the vendor or community to obtain patches or updates as soon as they become available and apply them promptly. 6. Consider temporary mitigation by disabling or isolating omni-tools functionality if feasible until a patch is released. 7. Educate development and operations teams about the risks of unsafe deserialization and promote secure coding practices to prevent similar vulnerabilities. 8. Implement endpoint detection and response (EDR) solutions to detect post-exploitation behaviors. 9. Prepare incident response plans specific to remote code execution scenarios to enable rapid containment and recovery.
