ZDI-26-363: Docker MCP Plugin OCI Image Label Parsing Argument Injection Remote Code Execution Vulnerability
A critical remote code execution vulnerability exists in Docker MCP Plugin due to improper validation of the io.docker.server.metadata OCI image label. Exploitation requires user interaction where the target references a malicious Docker image via a docker URI scheme. Successful exploitation allows arbitrary code execution on the host with root privileges. Docker has issued an update to address this vulnerability.
AI Analysis
Technical Summary
CVE-2026-55887 is a remote code execution vulnerability in Docker MCP Plugin caused by argument injection during OCI image label parsing. The vulnerability arises from insufficient validation of user-supplied strings used to prepare system call arguments, specifically in the handling of the io.docker.server.metadata label. An attacker can exploit this by tricking a user into referencing a malicious Docker image, leading to code execution as root on the host system. Docker has released a security update to fix this issue.
Potential Impact
An attacker who convinces a user to reference a malicious Docker image can execute arbitrary code on the host system with root privileges. This can lead to full system compromise, including confidentiality, integrity, and availability impacts. The vulnerability requires user interaction but does not require prior authentication.
Mitigation Recommendations
Docker has issued an official update that addresses this vulnerability. Users should apply the vendor-provided patch as soon as possible to remediate the issue. No additional mitigations are specified in the advisory.
