Closes the data-leak holes that survived the move of these controllers
from Yavsc.Api to Yavsc.Blogs. Circles are personal — a circle and its
membership should never be visible, modifiable, or deletable by anyone
other than its owner.
BlogAclApiController:
- GetBlogACL() was returning the full table; now filters by
Allowed.OwnerId == caller's uid, with an Include(a => a.Allowed)
so EF Core can push the filter into SQL instead of materialising
the whole table.
- Other endpoints (GetById, Put, Post, Delete) already enforced
ownership; left as is.
CircleApiController:
- GetCircle() (no id) now filters by OwnerId.
- GetCircle(id) now requires c.Id == id && c.OwnerId == uid;
returns 404 (not 403) on miss to avoid leaking the existence of
someone else's circle.
- PutCircle verifies the existing record is owned by the caller,
then forces circle.OwnerId = uid on the body (the client's value
is ignored). Returns ChallengeResult when the caller doesn't own
the record.
- PostCircle forces circle.OwnerId = uid (was trusting the body).
- DeleteCircle now filters by OwnerId; 404 on miss.
All checks use the same source of truth (User.FindFirstValue(
ClaimTypes.NameIdentifier)) that the existing BlogAclApiController
authz code already relies on.
These two controllers belong to the Blogs subsystem (their routes
/api/blogacl and /api/circle are blog-domain concerns, not the
generic Api surface). Moving them next to BlogApiController keeps
related code together and prepares the PostIt client to consume
them through the same BlogsApiUrl base address as the existing
BlogApiClient.
Mechanical changes only:
- Namespace Yavsc.Controllers -> Yavsc.Blogs.Controllers
- Drop unused 'using Yavsc.Helpers;' (no symbol in the new
compilation unit depends on it; the build confirms it was
dead since the controllers were first written)
- Fix typo in CircleApiController route: 'api/cirle' -> 'api/circle'
(any client trying to call the documented route was hitting 404)
No functional changes to authorization or query shape. The known
security gaps in these controllers (GetBlogACL and GetCircle
return unfiltered collections, DeleteCircle has no ownership
check) are deliberately left untouched in this commit and will
be addressed in a follow-up.
