== WHY (KEEP THIS — IT'S WHY THE FORK EXISTS) ==
Vanilla Plane's upload flow uses AWS S3 PostObject (presigned POST +
multipart/form-data + signed-policy-document). Cloudflare R2 AND
Backblaze B2 — the two most common self-host S3-compatible backends —
both return HTTP 501 NotImplemented for PostObject. Empirically verified
2026-04-30 against B2 s3.us-west-004.backblazeb2.com from inside Plane's
own prod api container, replicating Plane's exact boto3 call:
PUT against B2: 200 OK
POST against B2: 501 NotImplemented "This API call is not supported."
POST against R2: 501 NotImplemented (failure that started this thread)
The error code is `NotImplemented` (not `SignatureDoesNotMatch` etc),
meaning the server rejects the verb itself — no boto3 config, addressing-
style flag, or signature variant fixes it. Tested both path-style and
virtual-hosted-style URLs against B2; both fail identically for POST.
This patch rewrites the upload flow to use presigned PUT, which is
universally supported (R2, B2, AWS S3 native, MinIO, Wasabi, etc).
== WHAT (FIVE-FILE BACKEND, FIVE-FILE FRONTEND) ==
Backend:
* apps/api/plane/settings/storage.py — S3Storage.generate_presigned_post
now mints a presigned PUT URL via generate_presigned_url(HttpMethod="PUT").
Method name kept for caller compat. Response shape:
{url, method: "PUT", fields: {Content-Type, key}}.
* apps/api/plane/utils/openapi/responses.py — example response updated.
* apps/api/plane/tests/unit/settings/test_storage.py — 2 tests updated to
assert the new boto3 call.
Frontend:
* packages/types/src/file.ts — TFileSignedURLResponse.upload_data adds
optional method?: "PUT" | "POST"; drops AWS POST-form-data fields.
* packages/services/src/file/helper.ts — generateFileUploadPayload now
returns a TFileUploadRequest descriptor (url+method+body+headers) that
dispatches on method. POST branch kept for upstream parity but the
fork backend never emits POST.
* packages/services/src/file/file-upload.service.ts +
apps/web/core/services/file-upload.service.ts — uploadFile signature
changes from (url, FormData, progress?) to (payload, progress?).
* 5 caller sites updated (apps/web/core/services/file.service.ts x3,
issue_attachment.service.ts x1, sites-file.service.ts x1).
== TRADEOFFS ACCEPTED ==
* Lost: signed `content-length-range` enforcement at the storage layer.
Server-side validation in the API view still rejects oversized requests
with 413 before minting the URL, so a determined client could only
over-upload by misreporting size, capped at the bucket's own size limit.
* Different request shape on the wire (PUT with raw binary body vs POST
with multipart form). Externally invisible to users.
== ROLLBACK ==
If this becomes a maintenance nightmare:
git revert <this-commit-sha>
# rebuild + push images, swap compose tags, redeploy
After revert, uploads will only work against backends that implement
PostObject (MinIO, AWS S3 native). R2 and B2 will return 501 again.
== FULL DECISION RECORD ==

* fix: validate redirects in favicon fetching to prevent SSRF
The previous SSRF fix (GHSA-jcc6-f9v6-f7jw) only validated redirects for
the main page URL but not for the favicon fetch path. An attacker could
craft an HTML page with a favicon link that redirects to a private IP,
bypassing the IP validation and leaking internal network data as base64.
Extract a reusable `safe_get()` function that validates every redirect hop
against private/internal IPs and use it for both page and favicon fetches.
Resolves: GHSA-9fr2-pprw-pp9j

* fix: address PR review feedback for SSRF favicon fix
- Fix off-by-one in redirect limit: only raise RuntimeError when the
response is still a redirect after MAX_REDIRECTS hops, not when the
final response is a successful 200
- Return final URL from safe_get() so favicon href resolution uses the
correct origin after redirects instead of the original URL
- Add unit tests for validate_url_ip and safe_get covering private IP
blocking, redirect-following, and redirect limit enforcement
