SCA: security update for pydantic-ai, pydantic-ai-slim (GHSA-h4xc-3qfq-jf93)

high Tenable Cloud Security Plugin ID 473869

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
 1.34.0 until 1.107.4 and 2.28.0, the Agent.to_web() and clai web development chat endpoint has missing
 request content-type validation. A website visited by a developer can submit a browser-compatible request
 to a loopback-hosted chat server, causing the served agent to run and execute tools with the privileges
 and credentials of the local process; client-relayed approval decisions also leave requires_approval=True
 tools exposed. Binding to localhost does not prevent a browser page from reaching the loopback address.
 This issue is fixed in versions 1.107.4 and 2.28.0. (CVE-2026-107295)

Solution

Update the pydantic-ai library and its related packages to version 1.107.4 or later.
