Harden the web transport and bound the pages that run git Generated clone and LFS download links were derived from the request's Host header, with X-Forwarded-Proto believed from anyone. Those links are copied out of a page and pasted into a terminal, and the LFS hrefs are followed by a client, so a forged Host chose where somebody else's download went. Links now use public_url when it is configured, which is how a production instance is meant to be set up; without it the request origin is all there is, and forwarded headers are honoured only when git_http_client_ip_header is set, because that is the instance's statement that a proxy it trusts rewrites them. Site links follow the forge's scheme instead of always saying http, so an HTTPS forge does not link to a mixed-content site. The security headers now close the rest of the surface: object-src is none, inline styles are no longer allowed (no template or generated markup contains one), and Permissions-Policy, COOP and CORP are set. The CSRF check gained a second lock: when the browser says where a request came from, that origin must be this instance, on form posts and on the JSON ceremony endpoints alike. A missing Origin and Referer is not evidence, so only a request that names somewhere else is refused. The pages that shell out to git are bounded. Search, compare, blame, file history, commit history and both archive formats take a slot from a pool of eight and run under a 30-second deadline, which is attached to the git handle so the process is killed rather than left running after the reader has gone. Past a five-second wait for a slot the page answers 503 with Retry-After. Plain tar now takes the archive slot too: it is cheaper than gzip, not free, and both stream for as long as the client reads. Tests: clone URLs ignore a forged Host when public_url is set and honour forwarded headers only behind a declared proxy; LFS hrefs likewise; site links follow the scheme; the CSP has no unsafe-inline and names object-src; a saturated git pool answers 503 with Retry-After; a cross-origin post is refused with a valid CSRF token, end to end; the JSON endpoints refuse a foreign origin. Docs: public_url now explains that it decides generated links and that forwarded headers are only trusted with the proxy header set; Sites gains a same-site risk section recommending a separate registrable domain when sites are not trusted.
