Picks up @Timtech4u's PR #33, which has been waiting since April. The
design (CLI flag + threading through BrowserContext + http client) is
theirs and is correct; this is a clean rewrite on top of current main
because repeated rebase rounds had been reverting unrelated work that
landed in the meantime.
Issue #4 blocked all loopback / RFC1918 / link-local fetches to prevent
SSRF. The only escape was OBSCURA_ALLOW_PRIVATE_NETWORK=1, which is
process-wide and clunky in pipelines. Multiple users (@Timtech4u in
the original PR, then @duartemvix and @necrogami in the comment
thread) reported they cannot use obscura for development against
http://localhost:N without it.
Adds --allow-private-network as a global CLI flag, works on fetch,
serve, and scrape. Threads through BrowserContext::with_storage_and_network
and the http client's validate_url. CdpContext gets a new_full
builder and obscura_cdp::start_with_full_serve_options entry point so
'obscura serve --allow-private-network' lets Puppeteer/Playwright
navigate to localhost too. Default remains blocked.
Backward compat: the env var still works (OR'd with the flag inside
validate_url). All existing constructors and entry points unchanged.
Verified end-to-end against a local http.server on 127.0.0.1: fetch
and CDP Page.navigate both blocked by default, both succeed with the
flag. Public URLs unaffected. Integration suite 28/28, full workspace
cargo test all green.
* feat: cookie jar persistence + storage-dir + filtering fix (clean v4)
* fix: resolve build errors, add storage_dir param throughout server chain
* fix: storage_dir end-to-end, plus two test-literal field additions
Five issues found while testing PR 114 end-to-end.
Build fixes (two test literals out of sync with new struct fields):
- crates/obscura-net/src/cookies.rs: CookieInfo literal in
test_domain_matches_subdomain_without_leading_dot was missing the
same_site and expires fields added in #170.
- crates/obscura-cli/src/main.rs: Command::Fetch literal in
matcher_still_uses_fetch_variant was missing the new storage_dir
field. Without these cargo test --workspace would not compile.
run_fetch was branching between BrowserContext::with_storage (which
hardcodes proxy=None, stealth=false, user_agent=None) and
with_options (which has no storage_dir slot), so --storage-dir +
--proxy + --stealth silently dropped the proxy and stealth flags.
Same bug SGavrl flagged on dispatch.rs in the previous round, just on
the other code path. Switched to with_storage_full which carries all
four. Verified the fetch now errors out against an invalid proxy.
run_fetch --eval short-circuited the function before
context.save_cookies() ran, so cookies set during an eval session
were never persisted to {storage_dir}/cookies.json. Moved the save
above the return.
obscura serve loaded cookies on startup but never saved them
anywhere, so a session that set cookies via Network.setCookie or
navigation dropped them on shutdown. Subscribed to Ctrl-C once in
put a single save_cookies() after the loop so both the Ctrl-C path
and the channel-closed path persist cookies. Verified end-to-end.

GHSA-q55h-vfv9-qcr5. Any process able to reach the CDP port could
send Page.navigate {"url":"file:///etc/shadow"} and read arbitrary
local files (the process's UID's worth of read access). When obscura
runs as root inside Docker or as a systemd service that translates
straight into /etc/shadow, /root/.ssh/id_rsa, /proc/1/environ, etc.
Validate at the CDP boundary, not in obscura-net, so direct CLI
callers ("obscura fetch file://...") keep working. A new
BrowserContext.allow_file_access flag defaults to false; Page.navigate
returns an error when the requested URL is file:// and the flag is
off. CdpContext::new_with_security threads the flag from the server
entry point, and "obscura serve --allow-file-access" opts in for
local-HTML testing workflows.
Tested:
- Default obscura serve: CDP Page.navigate {file:///etc/passwd} ->
refused with descriptive error.
- obscura serve --allow-file-access: same call succeeds.
- obscura fetch file://... CLI path: unchanged, still reads the file.
- All earlier PoCs (GHSA-6pj9 JS->file SOP, GHSA-4789 sub-resource
SSRF, GHSA-4789 CSS template injection) still pass.
- cargo test --workspace clean.
obscura serve --user-agent <ua> only logged the value via tracing::info!
and never passed it to the CDP server, so every navigation kept using
the default Chrome UA string and httpbin.org/user-agent reported the
default rather than the override.
Plumb the option end-to-end:
- BrowserContext::with_full_options(id, proxy, stealth, user_agent)
initializes both BrowserContext::user_agent and the underlying
ObscuraHttpClient::user_agent RwLock at construction time so the
first navigation already sees the override.
- CdpContext::new_with_full_options forwards the UA to the default
BrowserContext.
- obscura_cdp::start_with_full_options accepts the UA and passes it
through cdp_processor.
- main.rs Serve arm calls start_with_full_options with the parsed UA.
- run_multi_worker_serve forwards --user-agent <ua> when spawning
worker subprocesses so multi-worker mode honors the flag too.
Existing two-arg start_with_options and three-arg with_options stay
as thin shims (call the full variant with None) so older callers and
the public crate API remain source-compatible.
Three new unit tests in obscura-browser cover the propagation, the
Chrome default fallback, and the legacy with_options path.
