SCA: security update for pydantic-ai, pydantic-ai-slim (GHSA-v2xh-2vp8-57h8)

medium Tenable Cloud Security Plugin ID 473872

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 1.107.2 and 2.24.0, web_fetch_tool, the WebFetch local fallback, and remote FileUrl media
 downloads buffer the complete HTTP response body before enforcing content-size controls. An attacker-
 influenced URL can stream an arbitrarily large response that exhausts process memory and crashes the
 worker; affected media types include ImageUrl, DocumentUrl, VideoUrl, and AudioUrl. SSRF protections
 remain effective, and the impact is limited to availability. This issue is fixed in versions 1.107.2 and
 2.24.0. (CVE-2026-107294)

Solution

Update the pydantic-ai library and its related packages to version 1.107.2 or later.
