* enhance: Add a few validation fixes from Sharkey See the original MR on the GitLab instance: https://activitypub.software/TransFem-org/Sharkey/-/merge_requests/484 Co-Authored-By: Dakkar <dakkar@thenautilus.net> * fix: primitive 2: acceptance of cross-origin alternate Co-Authored-By: Laura Hausmann <laura@hausmann.dev> * fix: primitive 3: validation of non-final url * fix: primitive 4: missing same-origin identifier validation of collection-wrapped activities * fix: primitives 5 & 8: reject activities with non string identifiers Co-Authored-By: Laura Hausmann <laura@hausmann.dev> * fix: primitive 6: reject anonymous objects that were fetched by their id * fix: primitives 9, 10 & 11: http signature validation doesn't enforce required headers or specify auth header name Co-Authored-By: Laura Hausmann <laura@hausmann.dev> * fix: primitive 14: improper validation of outbox, followers, following & shared inbox collections * fix: code style for primitive 14 * fix: primitive 15: improper same-origin validation for note uri and url Co-Authored-By: Laura Hausmann <laura@hausmann.dev> * fix: primitive 16: improper same-origin validation for user uri and url * fix: primitive 17: note same-origin identifier validation can be bypassed by wrapping the id in an array * fix: code style for primitive 17 * fix: check attribution against actor in notes While this isn't strictly required to fix the exploits at hand, this mirrors the fix in `ApQuestionService` for GHSA-5h8r-gq97-xv69, as a preemptive countermeasure. * fix: primitive 18: `ap/get` bypasses access checks One might argue that we could make this one actually preform access checks against the returned activity object, but I feel like that's a lot more work than just restricting it to administrators, since, to me at least, it seems more like a debugging tool than anything else. * fix: primitive 19 & 20: respect blocks and hide more Ideally, the user property should also be hidden (as leaving it in leaks information slightly), but given the schema of the note endpoint, I don't think that would be possible without introducing some kind of "ghost" user, who is attributed for posts by users who have you blocked. * fix: primitives 21, 22, and 23: reuse resolver This also increases the default `recursionLimit` for `Resolver`, as it theoretically will go higher that it previously would and could possibly fail on non-malicious collection activities. * fix: primitives 25-33: proper local instance checks * revert: fix: primitive 19 & 20 This reverts commit 465a9fe6591de90f78bd3d084e3c01e65dc3cf3c. --------- Co-authored-by: Dakkar <dakkar@thenautilus.net> Co-authored-by: Laura Hausmann <laura@hausmann.dev> Co-authored-by: syuilo <4439005+syuilo@users.noreply.github.com>
