Misc fixes regarding jobs and config (#7858 )

* Fix several scheduled job issues Several jobs could cause a panic, or stop without running through all items because of this panic. This could cause missed items until that panic somehow resolved it self, and probably would never work fully again. This could cause emergency access for example to never work again. Besides this, emergency access was also able to be panic if the wait-time was out-of-bounds and date/time calculation might fail. This is also fixed now by using `checked` functions and continue upon those issues so all awaiting items will be handled. Signed-off-by: BlackDex <black.dex@gmail.com> * Fix several possible panics and overflows Adjust several integer types to be a lower or unsigned type. Most types were too large, only because the function which used this value needed that specific type. But, this allowed too large values which either caused panics or might cause a DoS. This does however might possible cause configurations which have larger values, which are probably way too large anyway to be not loaded or use their defaults. During the config loading, either via env or json, it will show error logs regarding these items. Also fixed an issue with protected actions via OTP, it increased the attempt before it validated if the attempt limit was reached. This could cause an issue when set to `1`, that way it was never allowed, and `3` times would actually be `2`. Also added several config validation checks which otherwise would have prevent Vaultwarden to start, or login, so these will probably not cause issues, else users would already have issues. Signed-off-by: BlackDex <black.dex@gmail.com> * Show config errors on diagnostics page With the previous commits it is now possible to add a warning if their rare issues with loading of the config, either environment variables which we were not able to parse correctly, or if loading the `config.json` failed instead of just showing it wasn't used, while it does exists, which might be confusing.

Mathijs van Veluw	b71cb7a832	Misc fixes regarding jobs and config (#7858 ) * Fix several scheduled job issues Several jobs could cause a panic, or stop without running through all items because of this panic. This could cause missed items until that panic somehow resolved it self, and probably would never work fully again. This could cause emergency access for example to never work again. Besides this, emergency access was also able to be panic if the wait-time was out-of-bounds and date/time calculation might fail. This is also fixed now by using `checked` functions and continue upon those issues so all awaiting items will be handled. Signed-off-by: BlackDex <black.dex@gmail.com> * Fix several possible panics and overflows Adjust several integer types to be a lower or unsigned type. Most types were too large, only because the function which used this value needed that specific type. But, this allowed too large values which either caused panics or might cause a DoS. This does however might possible cause configurations which have larger values, which are probably way too large anyway to be not loaded or use their defaults. During the config loading, either via env or json, it will show error logs regarding these items. Also fixed an issue with protected actions via OTP, it increased the attempt before it validated if the attempt limit was reached. This could cause an issue when set to `1`, that way it was never allowed, and `3` times would actually be `2`. Also added several config validation checks which otherwise would have prevent Vaultwarden to start, or login, so these will probably not cause issues, else users would already have issues. Signed-off-by: BlackDex <black.dex@gmail.com> * Show config errors on diagnostics page With the previous commits it is now possible to add a warning if their rare issues with loading of the config, either environment variables which we were not able to parse correctly, or if loading the `config.json` failed instead of just showing it wasn't used, while it does exists, which might be confusing.

will-lottkowitz-prismandDaniel García	d1cbd027cd	Add revision_date to org policies (#7571 ) * Add revision_date to org policies Org policy JSON responses never included a revisionDate field, unlike every other synced entity. The official Bitwarden server always sets it, and current official clients (recently migrated to the WASM SDK's typed PolicyView) now assume it is always a valid date string. Its absence deserializes to undefined client-side, which then throws (RangeError: Invalid time value) when the client formats it, breaking the whole policy sync pipeline and silently emptying the vault view in the browser and desktop apps. Adds a revision_date column (mirroring the existing pattern used by Send), stamped on creation and bumped on every save. * Fix migration correctness for org policy revision_date Caught by review: SQLite rejects non-constant defaults in ALTER TABLE ADD COLUMN, so the sqlite migration would fail outright on every existing installation (vaultwarden's default backend) rather than the postgresql setup this was developed against. - sqlite/mysql: add the column with a constant placeholder default, then backfill via UPDATE, since neither allows a volatile default in ALTER TABLE ADD COLUMN (mysql does allow it, but a constant keeps the three backends' migrations symmetric). - mysql: use DATETIME instead of TIMESTAMP, matching this repo's existing revision_date columns, and backfill with UTC_TIMESTAMP() instead of a session-timezone-dependent CURRENT_TIMESTAMP. - postgresql: backfill with `now() AT TIME ZONE 'utc'` instead of a DEFAULT now(), since assigning timestamptz now() into this naive TIMESTAMP column would otherwise cast through the server's TimeZone GUC and store local wall-clock instead of UTC on non-UTC servers. - mysql/postgresql: add a real down.sql (DROP COLUMN) instead of leaving it empty. * Move org policy revision_date migration after the latest one --------- Co-authored-by: Daniel García <dani-garcia@users.noreply.github.com>	2026-10-07 19:19:26 +02:00

Permit email-only requests so the server will send the email 2FA token in that flow.\n\nModified: src/api/core/two_factor/email.rs Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * fix(email-2fa): use device-identifier fallback when no password hash submitted iOS clients call /api/two-factor/send-email-login with an email and DeviceIdentifier but without masterPasswordHash or authRequestId after receiving a 2FA-required response from the token endpoint. The previous empty else-block allowed any caller to trigger a 2FA email for any account knowing only the email address. Replace the empty block with a device-identifier-based fallback: - Look up the most-recently-active device via find_by_device_for_email2fa. - Verify the device's associated user email matches the submitted email. - Log (debug) when the fallback path is exercised for operator visibility. - Reject with the original error when no device identifier is provided or when the device maps to a different account. Fixes #7568 * Check the pending 2FA login for this user and device Look up the pending 2FA login for the user and device instead of the latest one on the device, answer a failed check with the same error and IP/username log detail as a wrong password, and escape the device id in the logs. --------- Co-authored-by: Arunabha-Mukhopadhyay <dkarunabha2006@gmail.com> Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>	2026-10-07 00:16:01 +02:00

Cassian433 Cassian433 Daniel García	42aa3ee1c7	Close WebSocket connections that stop responding (#7807 ) Both notification hubs send a Ping every 15 seconds but ignore the Pong, so the loop only ends on a Close frame, EOF or a socket error. When a client disappears without the TCP connection being closed, for example behind a reverse proxy or CDN that keeps the upstream connection open, none of these ever happens. The connection, its file descriptor and its map entry are then kept forever, until the process runs out of file descriptors and stops accepting connections and opening the database. Keep track of when something was last received from the client, Pongs included, and close the connection when nothing was received for 30 seconds. This is the default ClientTimeoutInterval of ASP.NET Core SignalR, which the official server uses.
