Описание
A flaw was found in Pydantic AI, a Python agent framework for building Generative AI applications. When an application is configured to allow local file downloads from untrusted URLs, a Server-Side Request Forgery (SSRF) vulnerability exists. This flaw allows an attacker to bypass existing security controls by encoding cloud metadata IP addresses using IPv4-mapped IPv6 formats. Successful exploitation could lead to the exposure of sensitive cloud Identity and Access Management (IAM) short-term credentials.

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 down
