Summary

CVE-2024-28088 is a high-severity Path Traversal (CWE-22) vulnerability in Langchain Langchain. Its CVSS base score is 8.1 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 24% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

This vulnerability is AI-related — categorised as LLM Application Platforms; in the Supply Chain and Deployment risk domain.

The strongest mitigations our analysis identified map to AC-3 (Access Enforcement) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

LangChain through version 0.1.10 contains a directory traversal flaw tracked as CVE-2024-28088 that affects the load_chain function in the langchain-core component. An actor who can supply the final portion of the path parameter is able to inject ../ sequences, which bypasses the intended restriction that configurations may be loaded only from the hwchase17/langchain-hub GitHub repository. The issue is assigned CWE-22 and carries a CVSS 3.1 score of 8.1.

An authenticated caller who controls the path argument can therefore retrieve arbitrary files from the local filesystem or cause the application to load attacker-supplied configuration, resulting in exposure of large-language-model API keys or remote code execution. The vulnerability is exploitable over the network without user interaction once the attacker can invoke load_chain with a crafted path.

A fix is present in langchain-core 0.1.29, delivered via the changes merged in pull request 18600 and reflected in the updated loading.py implementation. Public proof-of-concept code demonstrating both information disclosure and code execution has been published. The EPSS score remains at 0.1343 with no material increase from its recorded peak.

Vulnerability Data

LangChain through 0.1.10 allows ../ directory traversal by an actor who is able to control the final part of the path parameter in a load_chain call. This bypasses the intended behavior of loading configurations only from the hwchase17/langchain-hub GitHub repository.…

more

The outcome can be disclosure of an API key for a large language model online service, or remote code execution. (A patch is available as of release 0.1.29 of langchain-core.)

Mitigating Controls (NIST 800-53 r5) AI

Enforces the intended directory access authorizations that path traversal would otherwise bypass.

Input validation directly neutralizes special path elements before pathname construction occurs.

Least privilege reduces the impact of any unauthorized file access obtained via traversal.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly require input validation and path sanitization that block this weakness.

PR.PS-02 partial match
prevents

Patching/maintenance can remediate known path-traversal flaws in deployed software (partial prevention of exploitability) but does nothing to stop the coding defect from being introduced in the first place.

PR.AA-05 none match
prevents

PR.AA-05 defines and reviews access policies but does not address code-level pathname neutralization, so neither direction prevents CWE-22.

finds

Security testing in development catches path traversal via static/dynamic analysis.

prevents

Secure SDLC mandates input validation and path sanitization that directly prevent path traversal.

prevents

Application security requirements include rules for safe file handling and canonicalization.

prevents

Secure architecture principles require least-privilege file access and directory isolation.

prevents

Secure coding standards explicitly forbid unsafe path construction and mandate safe APIs.

mitigates

Information access restriction limits which files an application may read or write.
