CVE-2026-25640

CVSS3: 7.1

Описание

Pydantic AI is a Python agent framework for building applications and workflows with Generative AI. From 1.34.0 to before 1.51.0, a path traversal vulnerability in the Pydantic AI web UI allows an attacker to serve arbitrary JavaScript in the context of the application by crafting a malicious URL. In affected versions, the CDN URL is constructed using a version query parameter from the request URL. This parameter is not validated, allowing path traversal sequences that cause the server to fetch and serve attacker-controlled HTML/JavaScript from an arbitrary source on the same CDN, instead of the legitimate chat UI package. If a victim clicks the link or visits it via an iframe, attacker-controlled code executes in their browser, enabling theft of chat history and other client-side data. This vulnerability only affects applications that use Agent.to_web to serve a chat interface and clai web to serve a chat interface from the CLI. These are typically run locally (on localhost), but may also be deployed on a remote server. This vulnerability is fixed in 1.51.0.

A flaw was found in Pydantic AI. A remote attacker can exploit a path traversal vulnerability in the Pydantic AI web UI by crafting a malicious URL. This vulnerability arises from insufficient validation of the version query parameter, allowing the server to fetch and serve attacker-controlled HTML or JavaScript. If a victim clicks on such a link, malicious code can execute in their browser, potentially leading to the theft of sensitive client-side data, including chat history.

Отчет

This IMPORTANT vulnerability in Pydantic AI, as included in Red Hat Enterprise Linux AI, involves a path traversal flaw in the web UI's CDN URL construction. An attacker can exploit this by crafting a malicious URL, leading to arbitrary JavaScript execution in a victim's browser if they click the link. This primarily affects deployments utilizing Agent.to_web or clai web for chat interfaces.

Меры по смягчению последствий

To reduce exposure, restrict network access to the Pydantic AI web interface. If the application is deployed on a remote server, configure firewall rules to limit access to trusted networks or localhost. This prevents untrusted clients from reaching the vulnerable component. After applying firewall changes, ensure the rules are persistent and the firewall service is reloaded.
