The agent's HTTP_PROXY points at pipelock, so a request to
http://cred-proxy:9099/... arrives at pipelock; pipelock resolves
the host, sees an RFC1918 address (the bottle's internal Docker
network sits in 172.x), and 403's "SSRF blocked: cred-proxy
resolves to internal IP 172.20.0.4". Bypassing pipelock entirely
would also remove its body scanner from the agent->cred-proxy leg
— we want to keep that DLP coverage.
Pipelock has `ssrf.ip_allowlist` for exactly this: CIDRs that
override the built-in internal-IP block while api_allowlist + body
scanning + tls_interception keep firing.
Wiring:
- `pipelock_build_config` accepts `ssrf_ip_allowlist`; when
non-empty, emits an `ssrf: { ip_allowlist: [...] }` block.
- `pipelock_render_yaml` renders that block.
- `PipelockProxyPlan` gains `internal_network_cidr`.
- New `network_inspect_cidr(name)` helper reads the Docker-assigned
subnet via `docker network inspect`.
- launch.py: after `network_create_internal`, inspect the CIDR,
re-render the yaml with `ssrf_ip_allowlist=(cidr,)`, overwrite
the file in place; `DockerPipelockProxy.start` then docker-cp's
the updated content. Prepare's initial render stays unchanged
(CIDR isn't known yet at prepare time).
The exception scope is the bottle's own internal network only —
agent ↔ pipelock / git-gate / cred-proxy. Body scanning still
applies to the bytes flowing through pipelock; pipelock just no
longer treats those internal IPs as exfil targets.
