CVE-2025-11581 is a security vulnerability identified in PowerJob, an open-source distributed task scheduling framework, affecting versions 5.1.0 through 5.1.2. The vulnerability resides in the OpenAPIController component, specifically in the /openApi/runJob endpoint, where authorization checks are missing or improperly implemented. This flaw permits remote attackers to invoke job execution functionality without any authentication or authorization, effectively allowing them to run arbitrary scheduled jobs on the affected system. The vulnerability is exploitable over the network without requiring user interaction or privileges, making it highly accessible to attackers. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:P) indicates that the attack vector is network-based with low attack complexity, no privileges or user interaction needed, and partial impact on confidentiality due to potential exposure of job execution results or data. Although no public exploit code is currently known to be actively used in the wild, the public disclosure of the vulnerability increases the risk of exploitation by opportunistic attackers. PowerJob is commonly used in enterprise environments for task scheduling and automation, making this vulnerability significant for organizations relying on it for critical workflows. The lack of authorization could lead to unauthorized job execution, potentially resulting in data leakage, operational disruption, or further system compromise if malicious jobs are scheduled. The absence of vendor patches at the time of disclosure necessitates immediate compensating controls to mitigate risk.

For European organizations, the impact of CVE-2025-11581 can be substantial, particularly for those using PowerJob in production environments to automate critical business processes. Unauthorized remote execution of scheduled jobs could lead to disruption of automated workflows, data exposure, or execution of malicious code under the context of the scheduling system. This could affect data integrity and availability of services relying on these jobs. Organizations in sectors such as finance, manufacturing, telecommunications, and public services that depend on task automation may experience operational downtime or data breaches. Additionally, attackers could leverage this vulnerability as a foothold to pivot deeper into corporate networks. The medium severity rating reflects that while the vulnerability does not directly allow full system compromise, the unauthorized execution capability poses a meaningful risk to confidentiality and availability. European entities with regulatory requirements around data protection (e.g., GDPR) must consider the compliance implications of potential data exposure or service disruption caused by exploitation.

1. Apply official patches or updates from the PowerJob vendor as soon as they become available to address the missing authorization issue. 2. Until patches are released, restrict network access to the /openApi/runJob endpoint using firewall rules, VPNs, or API gateways to limit exposure to trusted internal users only. 3. Implement strong authentication and authorization controls on all API endpoints, especially those related to job execution and management. 4. Monitor logs and network traffic for unusual or unauthorized calls to the /openApi/runJob endpoint, setting up alerts for suspicious activity. 5. Conduct a thorough review of scheduled jobs and audit job execution histories to detect any unauthorized or anomalous activities. 6. Employ network segmentation to isolate systems running PowerJob from less trusted network zones. 7. Educate DevOps and security teams about the vulnerability to ensure rapid response and remediation. 8. Consider deploying Web Application Firewalls (WAFs) with custom rules to block unauthorized access attempts to vulnerable endpoints.
