CVE-2026-55887
HighCVSS 8.7Exploitation Probability (EPSS)
Low risk12th percentile - higher than 12% of all known CVEs
Summary
In Docker MCP Gateway from 0.21.0 until 0.42.2, the attacker-controlled io.docker.server.metadata OCI image label was unmarshalled into the catalog.Server structure for docker:// references and catalog snapshot imports. Runtime-shaping fields including Volumes, User, and ExtraHosts were appended to the docker run arguments without an origin allowlist. A malicious image author can force host filesystem or Docker socket mounts and UID 0 execution.
Risk Assessment
This container-creation-time boundary bypass can execute arbitrary code on the host and is not prevented by no-new-privileges. The risk occurs when a victim selects or pulls a malicious image.
Recommendation
Update Docker MCP Gateway to version 0.42.2. Avoid pulling and running untrusted images.

In MLflow from 3.12.0rc0 until 3.17.0, third-party scorer deserialization in mlflow/genai/scorers/base.py accepts request-selected descendants of allowed modules rather than requiring an exact allowed module. An attacker can place a Python module under a writable allowed package and invoke it via /ajax-api/3.0/mlflow/scorer/invoke, leading to code execution. Version 3.17.0 fixes the issue.

Sunhillo SureLine before 9.1.5 contains an authentication bypass vulnerability that allows an unauthenticated remote attacker to impersonate any user with an active web session by forging a session cookie containing only a cleartext username with no random identifier or integrity protection. Attackers can guess default account names such as Admin or sftp_user and submit a forged username cookie to satisfy the login check in checkLogin (libwebcmn.so) and networkDiag.cgi, chaining into root command execution.

Adobe Connect is affected by an Improper Control of Generation of Code ('Code Injection') vulnerability that could result in arbitrary code execution in the context of the current user. Exploitation requires user interaction, as a victim must visit a maliciously crafted URL or interact with a compromised web page. Scope is changed.

Private keys for eight eMudhra intermediate CA certificates have been compromised, which impacts certificate trust for outbound network request features of HCL Notes Client. An unauthenticated network attacker could spoof server certificates to execute a man-in-the-middle (MITM) attack, enabling them to intercept and/or modify the content of outbound TLS connections.

Adobe Campaign Classic (ACC) is affected by an Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability that could result in arbitrary code execution in the context of the current user. An attacker could execute arbitrary SQL commands, potentially gaining elevated access or control over the victim's account or session. Exploitation does not require user interaction, and scope is changed.

Original NVD description (English source)
MCP Gateway allows easy and secure running and deployment of MCP servers. From 0.21.0 until 0.42.2, Docker MCP Gateway YAML-unmarshalled the attacker-controlled io.docker.server.metadata OCI image label into the broad catalog.Server structure for direct docker:// references and catalog snapshot imports in pkg/oci/self_contained.go and pkg/workingset/workingset.go. Runtime-shaping fields including Volumes, User, and ExtraHosts were then appended to the docker run argument vector without an origin allowlist, allowing a malicious image author to request host filesystem or Docker socket mounts and UID 0 execution when a victim selected or pulled the image. This container-creation-time boundary bypass can execute arbitrary code on the host and is not prevented by no-new-privileges because no in-container privilege escalation is required. This issue is fixed in version 0.42.2.
