fix(api): redirect instead of 500 on an invalid password reset link - #9670
fix(api): redirect instead of 500 on an invalid password reset link#9670TemoSulava wants to merge 5 commits into
Conversation
ResetPasswordSpaceEndpoint looked the user up inside a try block that only caught DjangoUnicodeDecodeError, so a reset link whose uidb64 decodes to an unknown UUID raised User.DoesNotExist, one that decodes to a non-UUID string raised ValidationError, and one that is not decodable base64 raised ValueError - all three surfaced as unhandled 500s instead of the invalid-link page. Handle those cases on both reset endpoints and redirect to the reset-password page with INVALID_PASSWORD_TOKEN, keeping EXPIRED_PASSWORD_TOKEN for an undecodable uidb64. Because DjangoUnicodeDecodeError subclasses ValueError, that clause has to come first - in the app endpoint it sat on an outer try below `except (ValueError, ...)`, so it was already unreachable and an undecodable uidb64 answered 5125 there and 5130 on the space endpoint. Both endpoints now answer identical input identically. Adds contract tests covering every branch of both endpoints; the five that target the crash paths fail against the unpatched views. Fixes makeplane#9172

Review follow-up: TestResetPasswordAppEndpoint only exercised uid handling and the success path, so the invalid-token, missing-password and weak-password branches of ResetPasswordEndpoint were untested. Assert the redirect destination and that a rejected reset leaves is_password_autoset alone, and document the touched functions.

Thanks @coderabbitai — both points addressed in d0c09b6. Nitpick (app-route coverage): valid. Docstring coverage check: the five undocumented functions in the diff ( One correction worth recording: an earlier revision of the helper docstring claimed The tests still build the paths by hand — these are contract tests, so pinning the literal URL is the point — but the docstring now gives the accurate reason.

…the hash Review follow-up: - Substring checks on Location passed even if a branch redirected to the wrong page. Parse the redirect and compare origin, path and query exactly. Only the doubled slash after the space base path is normalized - base_host() already ends in a slash, so that quirk predates this branch; the same defect anywhere else now fails. - `not check_password(candidate)` only proved the submitted password was not stored, not that the existing one survived. Snapshot the hash before the request and assert it is unchanged. - Pin SPACE_BASE_PATH alongside the host so the expected paths do not depend on the ambient environment. - Cover token replay: a spent link must be rejected, since the token is hashed over the stored password.

Both findings check out — fixed in 1a2ecbe. 18 tests pass. Rejected resets preserving the original password — correct, and the gap was real. Exact redirect destination — also correct: assert (location.scheme, location.netloc) == EXPECTED_ORIGIN

…ashes
rstrip("/") erased the one difference between the two endpoints: the space
endpoint builds its redirects with f-strings and emits a trailing slash, the
app endpoint uses urljoin() and does not. Stripping let either one drift onto
the other's form unnoticed. Compare the path as emitted and carry the trailing
slash in the space constants; the targeted "/spaces//" normalization stays.

Reviewed the full head revision of both view files, not just the diff. The core change is correct: ValidationError is already imported in both files; DjangoUnicodeDecodeError -> UnicodeDecodeError -> ValueError, so ordering that clause first is required and is done right in both; git diff -w confirms the rest of each method is a verbatim dedent with the try now strictly narrower. I reproduced Django's decode paths locally -- "a" -> binascii.Error/ValueError, "not" -> b'\x9e\x8b' -> DjangoUnicodeDecodeError, valid-base64 non-UUID -> ValidationError from UUIDField.to_python -- and all three now redirect instead of 500ing. The test fixtures match repo conventions (contract marker registered, get_error_dict() returns exactly the two asserted keys, no set_password override on User that would clobber is_password_autoset), and _assert_redirect's /spaces// normalization tolerates both today's double slash and a future fix.
One low-severity finding inline. Two non-blocking notes:
- The space-endpoint tests live in
plane/tests/contract/app/test_password_reset.py. Purely organizational -- the file covers both endpoints and is otherwise fine. - The pre-existing double slash in the space redirect (
/spaces//accounts/reset-password/, frombase_host()already ending in/plus the f-string's leading/) is untouched by this PR and worth a separate one-line fix.

low -- Behavior change on the app endpoint: an undecodable-utf8 uidb64 (e.g. /auth/reset-password/not/<token>/) now returns error_code=5130 EXPIRED_PASSWORD_TOKEN where preview returns 5125 INVALID_PASSWORD_TOKEN, because this previously-dead handler is now reachable ahead of the tuple clause.
Concrete effect: a user who mangles a reset URL (or whose mail client truncates it) sees "Expired password token. Please try again." for a link that was never valid -- mildly misleading, and it may send them to re-request a link they already have. Both codes render as the same banner in apps/web/helpers/authentication.helper.tsx:292-298, so there is no functional breakage.
The PR description already flags this and offers to drop the handler instead. If you'd rather preserve 5125, delete the except DjangoUnicodeDecodeError clause from both files (the tuple clause catches it via ValueError) and update the two test_undecodable_uidb64_redirects cases, which currently pin the new code.
There was a problem hiding this comment.
Done — dropped the handler from both files in 67d08b9, 5125 preserved on the app endpoint.
Agreed on the reasoning: an undecodable uidb64 was never a valid link that later expired, so INVALID_PASSWORD_TOKEN is the accurate answer, and the remaining except (ValueError, ValidationError, User.DoesNotExist) covers it for free (DjangoUnicodeDecodeError → UnicodeDecodeError → UnicodeError → ValueError, and force_str is its only raise site). The import is gone from both files with smart_bytes/smart_str still in use, so it stays F401-clean.
One consequence worth stating outright, since it inverts which endpoint moves: on preview the space endpoint did answer 5130 here — its except wrapped the whole method body, so unlike the app one it was reachable. Deleting from both therefore restores the app endpoint to its exact preview behaviour and changes the space endpoint from 5130 to 5125. That is the direction I think is right, and it makes the two endpoints agree, which is the point of the PR — but it is a user-visible copy change on the space side ("Expired password token. Please try again." → "Invalid password token."), so flagging it rather than burying it. The two test_undecodable_uidb64_redirects cases now pin 5125 and the PR description is updated to match.
5130 is no longer emitted anywhere in apps/api. I left the enum entries in packages/constants/src/auth/index.ts:151 and both authentication.helper.tsx copies alone — they are Record<Enum, …> definitions, so a dead key breaks nothing, and removing them would strand any link already in flight from an older API.
Two test anchors added alongside, since both rejected-uidb64 fixtures now produce the same response and the old 5130 expectation was the only thing distinguishing them:
test_uidb64_fixtures_reach_their_branchespins that"a"raises insideurlsafe_base64_decode(binascii, never reachessmart_str) while"not"decodes tob"\x9e\x8b"and raisesDjangoUnicodeDecodeError. Without it, a change that stopped"not"from raising at all would leave the utf-8 branch untested with every test green — confirmed by mutation: pointing the fixture at"aGk"fails it.test_error_code_wire_valuespins5125/5020/5021as literals, since the tests otherwise read the expected code from the same dict the view writes; renumbering would stay green here and break the hardcoded TS constants.
20 passed. Reverting only the two view files gives 5 failed, 15 passed.
DjangoUnicodeDecodeError subclasses ValueError, so the tuple clause around the decode and the lookup already covers a uidb64 whose bytes are not utf-8. Drop the dedicated handler from both endpoints rather than ordering it first: such a link was never valid, so 5125 INVALID_PASSWORD_TOKEN describes it more accurately than 5130 EXPIRED_PASSWORD_TOKEN, and it is the code the app endpoint already returned on preview, where the same handler was unreachable. Only the space endpoint changes against preview (5130 -> 5125). 5130 is no longer emitted by the API; the frontend enum entries are left in place. Name the two rejected-uidb64 fixtures after the branch each one reaches and pin those raise sites, since both now produce the same response, and pin the error-code literals that packages/constants/src/auth/index.ts hardcodes.

Description
ResetPasswordSpaceEndpoint.post()looked the user up inside atryblock that only caughtDjangoUnicodeDecodeError, so a reset link whoseuidb64decodes to something unusable crashed with an unhandled 500 instead of redirecting to the invalid-link page:uidb64decodes toUser.DoesNotExisterror_code=5125error_code=5125django.core.exceptions.ValidationErrorerror_code=5125ValueError(binascii)error_code=5125error_code=5125DjangoUnicodeDecodeErrorerror_code=5130error_code=5125error_code=5125Both endpoints now catch
(ValueError, ValidationError, User.DoesNotExist)around the decode and the lookup only, and answer identical input identically.DjangoUnicodeDecodeErrorsubclassesUnicodeDecodeError→UnicodeError→ValueError, so the single tuple clause covers the invalid-utf-8 case too. Onpreviewthe space endpoint answered it with5130 EXPIRED_PASSWORD_TOKENwhile the app endpoint's identical handler sat below anexcept (ValueError, ...)on an innertryand was therefore dead code, answering5125. Per review, that handler is now deleted from both files rather than hoisted: an undecodableuidb64was never a valid link that later expired, so5125 INVALID_PASSWORD_TOKENis the accurate answer, and it is the code the app endpoint already returned.Behaviour delta versus
preview, in full: the four 500s above become 302s, and the space endpoint's invalid-utf-8 response changes from5130to5125.error_code=5130is no longer emitted by the API; the frontend enum entries for it are left untouched. The rest of each method is dedented out of the outertryverbatim (git diff -wshows only theexceptclauses moving), and the catch is narrower than before: it now wraps only the decode and the lookup, notset_password/save.Type of Change
Test Scenarios

5 failed, 15 passed— the three space-endpoint crash paths, the app endpoint's non-UUID crash, and the space endpoint's old 5130 response — so the tests pin the actual behaviour, not just the happy path.ruff checkandruff format --checkare clean on all three files.References
