CVE-2026-22812 Scanner

OpenCode is a software platform used by various organizations for development and execution of code and applications. It is generally adopted by developers and IT professionals aiming to streamline code management and execution processes. The platform integrates session creation and shell execution capabilities, allowing efficient handling of operations. As a versatile tool, OpenCode supports various programming languages and offers a user-friendly interface for both coding and deploying applications. With a broad customer base, OpenCode facilitates collaborative development and supports seamless code integration. Organizations employ OpenCode to improve productivity and enhance code deployment speeds across diverse environments.

The Remote Code Execution vulnerability in OpenCode arises from improper authentication controls on shell execution endpoints. This vulnerability enables unauthenticated attackers to execute arbitrary shell commands on the affected server. By exploiting this flaw, attackers can potentially gain control over the underlying system and compromise sensitive data. The vulnerability is particularly critical in environments where untrusted network access is possible, increasing the risk surface. RCE vulnerabilities are of high concern due to their potential for significant damage when exploited. Addressing this issue promptly is crucial for maintaining system integrity and preventing potential breaches.

Technical details of the vulnerability indicate that it manifests in the session creation and shell execution endpoints of OpenCode. These endpoints do not enforce proper authentication, thereby allowing unauthorized users to gain access. Attackers can exploit these endpoints by sending crafted HTTP requests to initiate a session and subsequently execute commands. The exploit targets specific URL paths, which include "/session" and "/session/{{session_id}}/shell", where session IDs can be manipulated to facilitate the attack. Once an attacker gains a valid session ID, they can execute any shell command, furthering their control over the server. The lack of proper authentication validation makes this a severe and easily exploitable vulnerability.

When this Remote Code Execution vulnerability is exploited, it may lead to severe consequences for the affected system. Malicious actors can execute commands remotely, which might compromise the entire system running OpenCode. Potential effects include data breaches, unauthorized access to sensitive information, and full system compromise. An attacker could also employ the vulnerability to distribute malware or backdoors, putting other systems at risk. Additionally, exploitation could disrupt normal operations, causing significant downtime and financial loss for affected organizations. The critical nature of this vulnerability necessitates immediate remediation efforts to mitigate potential risks.
