CVE-2026-100102 in Perforce
Summary
by MITRE • 10/05/2026
Perforce P4 Search container images prior to 2026.4.2 enable an unauthenticated Java debug interface. An attacker with network access to this interface can execute arbitrary code as the P4 Search service account, potentially leading to compromise of the connected P4 Server.

The vulnerability identified in Perforce P4 Search container images prior to version 2026.4.2 involves the unintended exposure of a Java Debug Wire Protocol (JDWP) interface without requiring authentication. This debug port, typically used by developers for remote debugging during software development and testing phases, was left enabled in production-ready container deployments. The presence of this unauthenticated endpoint allows any entity with network connectivity to the host or container to establish a connection to the JVM running the P4 Search service. This configuration error represents a significant deviation from security best practices, which dictate that debug interfaces should be disabled or strictly access-controlled in non-development environments to prevent unauthorized interaction with the application runtime.
From a technical perspective, the JDWP interface provides deep introspection capabilities into the Java Virtual Machine, including the ability to inspect threads, view stack traces, and crucially, execute arbitrary methods within the running process. An attacker leveraging this flaw can utilize standard debugging tools or custom scripts to invoke dangerous functions available in the P4 Search application classpath. Since the service runs under a specific system account with permissions necessary for its operational duties, successful exploitation allows the execution of commands with those same elevated privileges. This effectively bypasses traditional authentication mechanisms because the vulnerability exists at the infrastructure and runtime level rather than within the application's logical access control layer.
The operational impact of this vulnerability is severe, as it leads to a complete compromise of the P4 Search service instance. By executing arbitrary code, an attacker can read sensitive configuration files, extract database credentials, or manipulate search indices that may contain proprietary data. More critically, because the P4 Search component interacts with and relies on the core Perforce Helix Core server for authentication and repository access, compromising the search service provides a foothold to pivot attacks against the main P4 Server. This can result in unauthorized access to version control repositories, modification of source code history, or exfiltration of intellectual property stored within the depot. The attack path is straightforward and requires only network reachability, making it highly susceptible to automated scanning tools deployed by threat actors across the internet.
This vulnerability aligns with CWE-215, which describes the inclusion of debugging information that could reveal sensitive data, as well as CWE-489, Active Debug Code, where debug features remain active in production environments. In terms of offensive security frameworks such as MITRE ATT&CK, this flaw facilitates Initial Access through exposed services and enables Execution via remote code execution capabilities inherent to the JDWP protocol. It also supports Lateral Movement if the compromised service account has permissions extending beyond its immediate scope. To mitigate this risk, organizations must ensure that all container images are updated to version 2026.4.2 or later, where the debug interface is disabled by default in production configurations. Additionally, security teams should audit their deployment pipelines and runtime environments to verify that no other services have exposed debugging ports without proper network segmentation and authentication controls. Implementing strict egress and ingress firewall rules can further limit exposure if immediate patching is not feasible, ensuring that only trusted management networks can interact with administrative interfaces of critical infrastructure components.
