DescriptionGitHub Advisory

Langchain Helm Charts are Helm charts for deploying Langchain applications on Kubernetes. Prior to langchain-ai/helm version 0.12.71, a URL parameter injection vulnerability existed in LangSmith Studio that could allow unauthorized access to user accounts through stolen authentication tokens. The vulnerability affected both LangSmith Cloud and self-hosted deployments. Authenticated LangSmith users who clicked on a specially crafted malicious link would have their bearer token, user ID, and workspace ID transmitted to an attacker-controlled server. With this stolen token, an attacker could impersonate the victim and access any LangSmith resources or perform any actions the user was authorized to perform within their workspace. The attack required social engineering (phishing, malicious links in emails or chat applications) to convince users to click the crafted URL. The stolen tokens expired after 5 minutes, though repeated attacks against the same user were possible if they could be convinced to click malicious links multiple times. The fix in version 0.12.71 implements validation requiring user-defined allowed origins for the baseUrl parameter, preventing tokens from being sent to unauthorized servers. No known workarounds are available. Self-hosted customers must upgrade to the patched version.

AnalysisAI

LangSmith Studio contains a URL parameter injection vulnerability that allows attackers to steal authentication tokens, user IDs, and workspace credentials from users who click malicious links, enabling account takeover and unauthorized access to workspace resources. Both LangSmith Cloud and self-hosted Kubernetes deployments are affected, with exploitation requiring social engineering to trick authenticated users into clicking attacker-controlled URLs. No patch is currently available for this high-severity vulnerability (CVSS 8.1).
