    Server-side Request Forgery (SSRF)

    pydantic-ai-slim is an Agent Framework / shim to use Pydantic with LLMs, slim package

    Affected versions of this package are vulnerable to Server-side Request Forgery (SSRF) through UIAdapter.sanitize_messages in pydantic_ai_slim/pydantic_ai/ui/_adapter.py and VercelAIAdapter.from_request/dispatch_request in pydantic_ai_slim/pydantic_ai/ui/vercel_ai/_adapter.py. An attacker can cause the server to fetch arbitrary provider or cloud-storage files with its own credentials by submitting message history that contains client-controlled UploadedFile references in providerMetadata. This lets the attacker read files the application’s model-provider or storage identity can access, exposing private objects or other tenants’ data to the user.

    How to fix Server-side Request Forgery (SSRF)?

    Upgrade pydantic-ai-slim to version 1.106.0, 2.0.0b6 or higher.

    Server-side Request Forgery (SSRF)

    pydantic-ai-slim is an Agent Framework / shim to use Pydantic with LLMs, slim package

    Affected versions of this package are vulnerable to Server-side Request Forgery (SSRF) due to the blocklist bypass via additional IPv6 transition forms when force_download='allow-local' is enabled. An attacker can access sensitive cloud IAM short-term credentials by bypassing the cloud-metadata blocklist using IPv6 transition forms such as IPv4-compatible, SIIT/IVI, and local NAT64 IPv6 addresses. This is only exploitable if the application is running on a network that routes the affected IPv6 transition forms, such as NAT64-configured networks or networks with an ISATAP tunnel.

    Note:

    This issue is due to incomplete fix for CVE-2026-46678.

    How to fix Server-side Request Forgery (SSRF)?

    Upgrade pydantic-ai-slim to version 1.102.0, 2.0.0b3 or higher.

    Server-side Request Forgery (SSRF)

    pydantic-ai-slim is an Agent Framework / shim to use Pydantic with LLMs, slim package

    Affected versions of this package are vulnerable to Server-side Request Forgery (SSRF) via incomplete blocklist in is_private_ip function when force_download='allow-local' is enabled. An attacker can access sensitive cloud metadata information by submitting a specially crafted URL containing an IPv4-mapped IPv6, 6to4, or NAT64 encoded address that bypasses the intended blocklist. This is only exploitable if the application explicitly opts for FileUrl (ImageUrl, AudioUrl, VideoUrl, DocumentUrl) in force_download='allow-local' on a URL that is, or could be, influenced by untrusted input.

    Note:

    This issue is due to incomplete fix for CVE-2026-25580.

    How to fix Server-side Request Forgery (SSRF)?

    Upgrade pydantic-ai-slim to version 1.99.0 or higher.
