Future releases will require at least Python 3.6. Security advisory ----------------- This release contains fixes to the following security issues: - Denial of service attack via disk space or memory exhaustion ([CVE-2021-29430](https://cve.mitre.org/cgi-bin/cvename.cgi?name=2021-29430)). - SSRF due to missing validation of hostnames ([CVE-2021-29431](https://cve.mitre.org/cgi-bin/cvename.cgi?name=2021-29431)). - Malicious users could control the content of invitation emails ([CVE-2021-29432](https://cve.mitre.org/cgi-bin/cvename.cgi?name=2021-29432)). - Denial of service (via resource exhaustion) due to improper input validation ([CVE-2021-29433](https://cve.mitre.org/cgi-bin/cvename.cgi?name=2021-29433)). Although we are not aware of these vulnerabilities being exploited in the wild, Sydent server administrators are advised to update as soon as possible. Note that as well as changes to the package, there are also changes to the default email templates. If any templates have been updated locally, they must also be updated in line with the changes to the defaults for full protection from CVE-2021-29432. Features -------- - Accept an optional `web_client_location` argument to the invite endpoint which allows customisation of the email template. ([\#326](https://github.com/matrix-org/sydent/issues/326)) - Move templates to a per-brand subdirectory of `/res`. Add `templates.path` and `brand.default` config options.

This means that the recommended method for stable installations is now by using the PyPI project rather than a tarball of the `master` branch of this repository. See [the README](https://github.com/matrix-org/sydent/blob/v2.0.0/README.rst) for more details. **Warning:** This release deprecates v1 APIs for existing endpoints in favour of v2 APIs. Homeserver and client developers are encouraged to migrate their applications to the v2 APIs. See below for more information. Features -------- * Implement the items and MSCs from the [privacy project](https://matrix.org/blog/2019/09/27/privacy-improvements-in-synapse-1-4-and-riot-1-4) targeting identity servers. This introduces v2 APIs for every existing endpoint. v1 APIs are now deprecated and homeserver and client developers are encouraged to migrate their applications to the v2 APIs. * Add Python 3 compatibility to all of the codebase. Python 2 is still supported for now. * Delete stored invites upon successful delivery to a homeserver * Filter out delivered invites when delivering invites to a homeserver upon successful binding * Implement support for authenticating unbind queries by providing a `sid` and a `client_secret`, as per [MSC1915](https://github.com/matrix-org/matrix-doc/blob/master/proposals/1915-unbind-identity-server-param.md) * Add support for Prometheus and Sentry * Handle `.well-known` files when talking to homeservers * Validate `client_secret` parameters according to the Matrix specification * Return 400/404 on incorrect session validation * Add a default 10,000 address limit on v2 `/lookup` (which supports multiple lookups at once) Documentation ------------- * Rewrite part of the README to make it more user-friendly Bugfixes -------- * Fix a bug that would prevent requests to the `/store-invite` endpoint with JSON payloads from being correctly processed * Fix a bug where multiple cleanup tasks would be unnecessary spawned * Fix logging so Sydent doesn't log 3PIDs when processing lookup requests * Fix incorrect HTTP response from `/3pid/getValidated3pid` endpoint on failure. * Prevent a single failure from aborting the federation loop * Fix federation lookups in `/onBind` callbacks * Don't fail the unbind request if the binding doesn't exist * Fix the signing servlet missing a reference to the Sydent object * Fix content types & OPTIONS requests Internal changes ---------------- * Add unit tests to test startup and replication * Add support for testing with `matrix-is-tester` * Remove instances of `setResponseCode(200)` Changes in [1.0.3](https://github.com/matrix-org/sydent/releases/tag/v1.0.3) (2019-05-03) ========================================================================================= * Use trustRoot instead of verify for request verification Security Fixes -------------- * Ensures that authentication tokens are generated using a secure random number generator, ensuring they cannot be predicted by an attacker. Thanks to @opnsec for identifying and responsibly disclosing the issue! * Mitigate an HTML injection bug where an invalid room_id could result in malicious HTML being injected into validation emails. Thanks to @opnsec for identifying and responsibly disclosing this issue too! * Randomise session_ids to avoid leaking info about the total number of identity validations, and whether a given ID has been validated. Thanks to @fs0c131y for this one. * Don't send tracebacks to the browser when errors occur. Changes in [1.0.2](https://github.com/matrix-org/sydent/releases/tag/v1.0.2) (2019-04-18) ========================================================================================= Security Fixes -------------- * Fix for validating malformed email addresses: https://github.com/matrix-org/sydent/commit/3103b65dcfa37a9241dabedba560c4ded6c05ff6 Changes in [1.0.1](https://github.com/matrix-org/sydent/releases/tag/v1.0.1) (2019-04-18) ========================================================================================= Release pointed to wrong commit, fixed by 1.0.2
