SCA: security update for pydantic-ai, pydantic-ai-slim (GHSA-v36g-jcw9-x7cw)

medium Tenable Self-Hosted Container Security Plugin ID 473880

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Pydantic AI is a Python agent framework for building applications and workflows with Generative AI. From
 1.77.0 until 1.107.7 and 2.52.0, the local web_fetch_tool and the WebFetch local fallback can consume
 excessive CPU and memory during HTML-to-Markdown conversion of attacker-controlled HTML containing deeply
 nested block elements. Conversion repeatedly reprocesses accumulated text and can greatly expand
 intermediate output before the returned-content limit is applied, allowing a model-directed fetch to delay
 other work in the process. Provider-native web fetching is not affected. This issue is fixed in versions
 1.107.7 and 2.52.0. (CVE-2026-107287)

Solution

Update the pydantic-ai library and its related packages to version 1.107.7 or later.
