CVE-2026-25750 Mar 04, 22:16 HIGH This Week

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).

CVE-2026-55443 Jun 22, 17:21 PyPI MEDIUM PATCH This Month

Path traversal and sandbox escape in LangChain prior to 1.3.9 allow untrusted inputs - including LLM-generated content steered by adversarial prompts - to escape a configured filesystem root boundary. Three components are affected: a file-search agent middleware that validates a starting directory but not glob patterns or symlink targets; prompt and chain/agent configuration loaders that resolve path fields without root confinement; and path-prefix authorization logic that performs string-prefix comparison without segment boundaries, allowing sibling paths to bypass access controls. No public exploit code has been identified at time of analysis and this CVE does not appear in CISA KEV, but the risk is meaningful for any deployment that exposes LangChain filesystem agents to untrusted user input or LLM prompt injection.

LangGraph SQLite Checkpoint versions 1.0.9 and prior are vulnerable to unsafe deserialization of msgpack-encoded objects, allowing attackers with write access to the checkpoint database to execute arbitrary code when checkpoints are loaded. This vulnerability affects Python-based AI/ML applications using LangGraph's persistence layer and requires adversary control of the backing storage to exploit.

CVE-2026-27795 Feb 25, 18:23 npm MEDIUM PATCH This Month

LangChain's RecursiveUrlLoader in @langchain/community versions prior to 1.1.18 fails to validate redirect targets, allowing authenticated attackers to bypass SSRF protections by redirecting from whitelisted URLs to internal or metadata endpoints. An attacker with user credentials can exploit this to access sensitive internal resources or cloud metadata services through automatic redirect following. Affected applications should upgrade to version 1.1.18, which disables automatic redirects and re-validates each redirect destination.

Denial-of-service in LangChain versions up to and including 0.3.1 lets remote attackers exhaust CPU by feeding a crafted string into the MRKLOutputParser.parse() method, whose backtracking-prone regular expression exhibits catastrophic backtracking (ReDoS). Because MRKL agents parse LLM output to extract tool actions, an attacker who can influence that text - typically via prompt injection in downstream applications - can stall or hang the parsing thread. Publicly available exploit code exists (huntr bounty), though EPSS is low at 0.08% and it is not on the CISA KEV list.

Denial-of-service in LangChain versions up to and including 0.3.1 lets remote attackers exhaust CPU by feeding a crafted string into the MRKLOutputParser.parse() method, whose backtracking-prone regular expression exhibits catastrophic backtracking (ReDoS). Because MRKL agents parse LLM output to extract tool actions, an attacker who can influence that text - typically via prompt injection in downstream applications - can stall or hang the parsing thread. Publicly available exploit code exists (huntr bounty), though EPSS is low at 0.08% and it is not on the CISA KEV list.

A SQL injection vulnerability exists in LangGraph SQLite Checkpoint, an implementation of LangGraph CheckpointSaver for SQLite databases. The vulnerability affects versions 3.0.0 and below of the langgraph-checkpoint-sqlite Python package, allowing attackers with local access and low privileges to manipulate SQL queries through unvalidated metadata filter keys in checkpoint search operations. A proof-of-concept exploit is publicly available, though the EPSS score of 0.02% (6th percentile) suggests minimal active exploitation in the wild currently.
