CVE-2023-36095

An issue in Harrison Chase langchain allows an attacker to execute arbitrary code via the PALChain,from_math_prompt(llm).run in the python exec method.

CVE-2023-38896

An issue in Harrison Chase langchain before version 0.0.236 allows a remote attacker to execute arbitrary code via the from_math_prompt and from_colored_object_prompt functions.

CVE-2023-34540

Langchain before v0.0.225 was discovered to contain a remote code execution (RCE) vulnerability in the component JiraAPIWrapper (aka the JIRA API wrapper). This vulnerability allows attackers to execute arbitrary code via crafted input. As noted in the "releases/tag" reference, a fix is available.

CVE-2023-36188

An issue in langchain allows a remote attacker to execute arbitrary code via the PALChain parameter in the Python exec method.

CVE-2023-39631

An issue in LanChain-ai Langchain v.0.0.245 allows a remote attacker to execute arbitrary code via the evaluate function in the numexpr library.

Patches: Released in v.0.0.308. numexpr dependency is optional for langchain.

CVE-2023-36281

An issue in langchain v.0.0.171 allows a remote attacker to execute arbitrary code via the via the a json file to the load_prompt parameter. This is related to __subclasses__ or a template.

CVE-2023-36258

An issue in langchain allows an attacker to execute arbitrary code via the PALChain in the python exec method.

CVE-2023-34541

Langchain 0.0.171 is vulnerable to Arbitrary code execution in load_prompt.

CVE-2023-46229

LangChain before 0.0.317 allows SSRF via document_loaders/recursive_url_loader.py because crawling can proceed from an external server to an internal server.

CVE-2023-39659

An issue in langchain langchain-ai before version 0.0.325 allows a remote attacker to execute arbitrary code via a crafted script to the PythonAstREPLTool._run component.

CVE-2023-32786

In Langchain before 0.0.329, prompt injection allows an attacker to force the service to retrieve data from an arbitrary URL, essentially providing SSRF and potentially injecting content into downstream tasks.

CVE-2024-0243

With the following crawler configuration:

from bs4 import BeautifulSoup as Soup

url = "https://example.com"
loader = RecursiveUrlLoader(
    url=url, max_depth=2, extractor=lambda x: Soup(x, "html.parser").text 
)
docs = loader.load()

An attacker in control of the contents of https://example.com could place a malicious HTML file in there with links like "https://example.completely.different/my_file.html" and the crawler would proceed to download that file as well even though prevent_outside=True.

Resolved in https://github.com/langchain-ai/langchain/pull/15559

CVE-2024-28088

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. The outcome can be disclosure of an API key for a large language model online service, or remote code execution.

CVE-2024-3571

langchain-ai/langchain is vulnerable to path traversal due to improper limitation of a pathname to a restricted directory ('Path Traversal') in its LocalFileStore functionality. An attacker can leverage this vulnerability to read or write files anywhere on the filesystem, potentially leading to information disclosure or remote code execution. The issue lies in the handling of file paths in the mset and mget methods, where user-supplied input is not adequately sanitized, allowing directory traversal sequences to reach unintended directories.

CVE-2023-38860

An issue in LangChain prior to v.0.0.247 allows a remote attacker to execute arbitrary code via the prompt parameter.

CVE-2023-36189

SQL injection vulnerability in langchain allows a remote attacker to obtain sensitive information via the SQLDatabaseChain component.

CVE-2024-2965

Denial of service in SitemapLoader Document Loader in the langchain-community package, affecting versions below 0.2.5. The parse_sitemap method, responsible for parsing sitemaps and extracting URLs, lacks a mechanism to prevent infinite recursion when a sitemap URL refers to the current sitemap itself. This oversight allows for the possibility of an infinite loop, leading to a crash by exceeding the maximum recursion depth in Python. This vulnerability can be exploited to occupy server socket/port resources and crash the Python process, impacting the availability of services relying on this functionality.

CVE-2024-8309

A vulnerability in the GraphCypherQAChain class of langchain-ai/langchain version 0.2.5 allows for SQL injection through prompt injection. This vulnerability can lead to unauthorized data manipulation, data exfiltration, denial of service (DoS) by deleting all data, breaches in multi-tenant security environments, and data integrity issues. Attackers can create, update, or delete nodes and relationships without proper authorization, extract sensitive data, disrupt services, access data across different tenants, and compromise the integrity of the database.

CVE-2023-32785

In Langchain before 0.0.247, prompt injection allows execution of arbitrary code against the SQL service provided by the chain.
