Detailsinfo

A vulnerability was found in langchain-ai LangGraph up to 0.4.31. It has been declared as problematic. This vulnerability affects some unknown processing of the component CLI. The manipulation with an unknown input leads to a information disclosure vulnerability. The CWE definition for the vulnerability is CWE-200. The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. As an impact it is known to affect confidentiality. CVE summarizes:

The LangGraph CLI is the official command-line interface for LangGraph. From 0.4.15 until 0.4.32, langgraph deploy --verbose passes a temporary registry push token on standard input to docker login --password-stdin, but the CLI subprocess helper prints command input in verbose mode. Anyone who can read resulting CI logs or terminal recordings before the token's maximum 12-hour expiration can pull deployment images or push images to that deployment's image repository. Deployments without --verbose and remote image builds are not affected, and the token alone cannot update a deployment to execute a pushed image. This issue is fixed in version 0.4.32.

The advisory is shared for download at github.com. This vulnerability was named CVE-2026-115885 since 10/23/2026. The exploitation appears to be easy. The attack can be initiated remotely. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1592.
