SCA: security update for pydantic-ai, pydantic-ai-slim (GHSA-cqp8-fcvh-x7r3)

medium Tenable Self-Hosted Container Security Plugin ID 442293

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 Generative AI applications. In versions 1.56.0
 through 1.98.0, when an application opts a URL into force_download='allow-local' (disabling the default
 block on private/internal IPs), the cloud-metadata blocklist could be bypassed by encoding the metadata IP
 in an IPv6 transition form (IPv4-mapped IPv6, 6to4, or NAT64), exposing cloud IAM short-term credentials
 on dual-stack or translated networks. This is an incomplete fix of GHSA-2jrp-274c-jhv3 / CVE-2026-25580,
 whose remediation did not hold for IPv6-encoded forms of the metadata IPs. An application is affected only
 if it explicitly opts a FileUrl (ImageUrl, AudioUrl, VideoUrl, DocumentUrl) into force_download='allow-
 local' on a URL influenced by untrusted input; it is not affected when using bundled integrations to
 ingest user input (Agent.to_web / clai web, VercelAIAdapter, AGUIAdapter / Agent.to_ag_ui), since they do
 not propagate force_download from external data, nor when downloading only from developer-controlled URLs.
 This issue has been fixed in version 1.99.0. (CVE-2026-46678)

Solution

Update the pydantic-ai library and its related packages to version 1.99.0 or later.
