Mathijs van Veluw	7c188967e7	Update crates, Rust and other dependencies (#7814 ) - Update Rust to v1.99.0 - Updated GitHub Actions - Updated DataTables Signed-off-by: BlackDex <black.dex@gmail.com>	2026-10-05 14:39:21 +02:00
Daniel García	895ec2b1e7	Align API behaviour with upstream and return errors on malformed input (#7810 ) - Attachments: reject a declared v2 attachment size above the upload limit, keep display sizes within the largest unit, and make download links valid for 1 minute like upstream. - Ciphers: moving a personal cipher into an organization needs collection write access or full access, like upstream. - Events: /events/collect only accepts the client event types upstream accepts. - Client IP: for list headers like X-Forwarded-For, use the rightmost address that isn't in IP_HEADER_TRUSTED_PROXIES, reading every occurrence. - Prelogin: unknown emails get stable KDF settings from upstream's list. - Login with device: an auth request can be used for one login, like upstream. - Directory Connector import: never revokes, restores or removes Owners, like upstream. - SSO: check the PKCE verifier again when the code exchange is reused during 2FA, and accept the same redirect URIs as upstream (desktop localhost callback for AppImage and dev builds, CLI on ports 8065-8070). - Identity: send the merged master password policy in the 2FA response and use PascalCase policy keys in identity responses, like upstream. Organization API key login no longer needs device fields. Recovery code login normalises the code, uses upstream's error message, logs a failed 2FA event and sends a "two-step login recovered" email. - Add GET /api/accounts/keys. - Return errors instead of panicking on malformed event dates, cipher data, key rotation cipher ids, bulk confirm entries and YubiKey OTPs.	2026-10-05 14:38:01 +02:00
Daniel García	1f99d9d276	Remove legacy API endpoints and compatibility code dropped upstream (#7809 ) Remove endpoints, response fields, feature flags and compatibility code that upstream Bitwarden has removed and that no current client uses: - Legacy POST /identity/accounts/register and POST /api/accounts/prelogin; register/finish is rate limited like the other unauthenticated endpoints. - Legacy organization routes: PUT groups/{id}/users, PUT policies/{type}/vnext, PUT users/{id}/reset-password, GET billing/metadata, and the POST aliases of the organization, collection, group and member PUT/DELETE routes. - POST /two-factor/disable (PUT stays). - ResetMasterPassword, captchaBypassToken, the legacy registration name field, userIsManagedByOrganization/managedByOrganization and accessAll. - The automatic email 2FA code for clients older than 2025.5.0. - DUO_USE_IFRAME and the Duo Traditional Prompt code. - Experimental client feature flags that no client reads anymore. - Web vault CSS selectors for web vaults older than 2025.5.1. Also accept the PascalCase fields Android 2026.9.0+ sends on registration and password change, and align a few account, login/2FA and organization checks with upstream. Adds tests for the registration body formats.	2026-10-04 22:16:55 +02:00

Mathijs van Veluw	061694d0cb	Fix cortex-a53 build issues when using xx-cargo (#7774 ) When using xx-cargo it uses a different linker then the default one. This causes some default fixes Debian/Ubuntu add for the Cortex-A53 architectures to not be included. This commit fixes that by checking if the target architecture is arm64 and if so, will add the needed fix argument. This should prevent issues reported here #7754. We can not say this with 100% certainty since this bug sometimes appears and sometimes it does not. Fixes #7754 Signed-off-by: BlackDex <black.dex@gmail.com>	2026-09-25 21:53:06 +02:00
Daniel García	32098ca7d1	Require confirmed membership for user access checks, not for admin views (#7763 )	2026-09-23 23:22:43 +02:00
Abhi ShandilyaandDaniel García	d2660324e6	Fix revoked org members retaining access to org ciphers (#7554 ) The cipher access restriction queries (direct collection access, group collection access, and full access via groups) never checked the organization membership status. Since users_collections and groups_users rows are kept when a membership is revoked, revoked (and not yet confirmed) members kept read, write, delete, attachment and collection-move access to org ciphers via the direct-by-UUID endpoints. Require a confirmed membership in the cipher's organization in all three queries, matching the behavior of the sync queries.

Berk D. Demir	3347698712	Add `pm-34171-card-scanner` feature flag (#7477 ) Introduced in 2026.4.1 Mobile releases (Android and iOS), enables use of device camera to autofill a card type item. N.B. This feature relies on Google ML Kit. F-Droid policy disallows Google ML Kit. Because of this, F-Droid builds do not ship with card scanner feature.

Chase DouglasandBlackDex	5b51b60f94	Route service clients through shared HTTP setup (#7639 ) * storage: route OpenDAL through HTTP client OpenDAL 0.58 requires applications to provide an HTTP transport. Its default installer creates a standalone client, bypassing Vaultwarden DNS, redirect, proxy, timeout, and request configuration. Build the client through the internal HTTP interface and inject it into OpenDAL's public reqwest transport. * http: honor block setting on redirects Clients can disable host blocking for administrator-configured private services. DNS resolution honors this setting, but the redirect policy still performs config-backed host checks. Capture the setting in the redirect policy and skip those checks when blocking is disabled. This also avoids re-entering CONFIG when a remote configuration request is redirected during startup. * http: make DNS setup bootstrap-safe Remote configuration can require an HTTP client while CONFIG is still initializing. Building the DNS resolver currently reads CONFIG.dns_prefer_ipv6(), so loading an S3-backed config can deadlock. Build one resolver without consulting CONFIG. Order addresses for each lookup using the merged setting when available, falling back to the environment and then IPv4-first during bootstrap. * aws: use internal HTTP client The AWS SDK connector builds a raw reqwest client, bypassing Vaultwarden TLS, DNS, redirect, proxy, timeout, and request setup. Construct it through the internal HTTP client interface and retain the standard ten-second request deadline. Permit private AWS metadata and service endpoints by disabling non-global IP blocking. Preserve timeout errors when adapting reqwest failures to the AWS SDK so the runtime receives the correct connector error category. * Added comment for the prefer IPv function Signed-off-by: BlackDex <black.dex@gmail.com> --------- Signed-off-by: BlackDex <black.dex@gmail.com> Co-authored-by: BlackDex <black.dex@gmail.com>	2026-09-09 14:30:25 +02:00

niniconi	b7667e27bf	fix: Correct invalid comment syntax in .dockerignore (#7274 ) Docker only recognizes `#` as a valid comment indicator in .dockerignore files. Using `//` causes the lines to be incorrectly parsed as glob patterns rather than comments. While this may not cause fatal errors if no matching files exist, it is syntactically invalid and could lead to unexpected behavior. Corrected the syntax to use `#`.	2026-09-08 13:42:58 +02:00

The CRahn	277e1536eb	Log IP/username on two-factor email-login credential failures (#7654 ) The three "Username or password is incorrect" errors in send_email_login() (email.rs) don't log the client IP or submitted identifier, unlike the equivalent wrong-password error in password_login() (identity.rs), which logs both via format!("IP: {}. Username: {username}.", ip.ip). This makes the two code paths inconsistent for the same underlying error, and means log-based tooling that keys on the identity.rs error's "IP: x.x.x.x" pattern can't do the same for this endpoint. Bring email.rs's three call sites in line with identity.rs's existing format. The two email-present branches log IP+Username (the email submitted); the device-identifier-only branch (SSO path, no email in scope) logs IP+Device instead of fabricating a username. Verified: cargo build/test/clippy/fmt all pass with the sqlite feature (matching one leg of this repo's own CI matrix), including the two existing unit tests in this file.	2026-09-08 12:13:51 +02:00
