Ruben FiszelandClaude Opus 4.8 27ead8d084 fix(ai): disable redirects on worker AI provider client (GHSA-5q4v) (#10122)
* fix(ai): disable redirects on worker AI provider client (GHSA-5q4v)

The worker AI request path issued provider requests with the shared
HTTP_CLIENT, which follows up to 10 redirects without revalidating each
hop. SSRF validation on the provider base_url is single-shot, so a public
base_url could 3xx the worker into a private/internal host (e.g. cloud
metadata), bypassing the private-endpoint protection. The API proxy was
already hardened in #9370; the worker path was missed.

Add a dedicated AI_HTTP_CLIENT with redirects disabled and use it for the
user-controlled provider endpoint, mirroring the API proxy client.

* fix(ai): add ALLOW_AI_BASE_URL_REDIRECTS debug escape hatch

Off by default (redirects stay disabled). When set, restores redirect
following on the AI HTTP client for debugging non-standard/self-hosted
gateways, with a startup warning that it weakens SSRF protection.

* docs(ai): correct redirect comment for the escape hatch override

* docs(ai): condense redirect invariant comments per review

Anchor the SSRF rationale to ALLOW_AI_BASE_URL_REDIRECTS (the knob that
would break it) and shorten the AI_HTTP_CLIENT and call-site comments to
avoid restating it at multiple sites (AGENTS.md).
