8.4.0 - released 2023-02-15

Added

  • You can now set a leeway for time drift between servers when validating a JWT (PR #1304)

Security

  • Access token requests that contain a code_verifier but are not bound to a code_challenge will be rejected to prevent a PKCE downgrade attack (PR #1326)

8.3.6 - released 2022-11-14

Fixed

  • Use LooseValidAt instead of StrictValidAt so that users aren't forced to use claims such as NBF in their JWT tokens (PR #1312)

8.3.5 - released 2022-05-12

Fixed

  • Use InMemory::plainText('empty', 'empty') instead of InMemory::plainText('') to avoid new empty string exception thrown by lcobucci/jwt (PR #1282)

8.3.4 - released 2022-04-07

Fixed

  • Server previously rejected valid uris with custom schemes. Now use league/uri for parsing to accept all valid uris (PR #1274)

8.3.3 - released 2021-10-11

Security

  • Removed the use of LocalFileReference() in lcobucci/jwt. Function deprecated as per GHSA-7322-jrq4-x5hf (PR #1249)

8.3.2 - released 2021-07-27

Changed

  • Conditionally support the StrictValidAt() method in lcobucci/jwt so we can use version 4.1.x or greater of the library (PR #1236)

  • Keys are always stored in memory now and are not written to a file in the /tmp directory (PR #1180)
  • The regex for matching the bearer token has been simplified (PR #1238)

8.3.1 - released 2021-06-04

Added

  • The server will now validate redirect uris according to rfc8252 (PR #1203)
  • Events emitted now include the refresh token and access token payloads (PR #1211)
  • Use the revokeRefreshTokens() function to decide whether refresh tokens are revoked or not upon use (PR #1189)

Changed

  • Keys are now validated using openssl_pkey_get_private() and openssl_pkey_get_public() instead of regex matching (PR #1215)

Fixed

  • The server will now only recognise and handle an authorization header if the value of the header is non-empty. This is to circumvent issues where some common frameworks set this header even if no value is present (PR #1170)
  • Added type validation for redirect uri, client ID, client secret, scopes, auth code, state, username, and password inputs (PR #1210)
  • Allow scope "0" to be used. Previously this was removed from a request because it failed an empty() check (PR #1181)

8.2.4 - released 2020-12-10

Added

  • Add a getRedirectUri function to the OAuthServerException class (PR #1123)
  • Support for PHP 8.0 (PR #1146)

Removed

  • Removed support for PHP 7.2 (PR #1146)

Fixed

  • Fix typo in parameter hint. code_challenged changed to code_challenge. Thrown by Auth Code Grant when the code challenge does not match the regex. (PR #1130)
  • Undefined offset was returned when no client redirect URI was set. Now throw an invalidClient exception if no redirect URI is set against a client (PR #1140)

8.1.1 - released 2020-07-01

Fixed

  • If you provide a valid redirect_uri with the auth code grant and an invalid scope, the server will use the given redirect_uri instead of the default client redirect uri (PR #1126)

8.1.0 - released 2020-04-29

Added

  • Added support for PHP 7.4 (PR #1075)

Changed

  • If an error is encountered when running preg_match() to validate an RSA key, the server will now throw a RuntimeException (PR #1047)
  • Replaced deprecated methods with recommended ones when using Lcobucci\JWT\Builder to build a JWT token. (PR #1060)
  • When storing a key, we no longer touch the file before writing it as this is an unnecessary step (PR #1064)

Fixed

  • Clients are now explicitly prevented from using the Client Credentials grant unless they are confidential to conform with the OAuth2 spec (PR #1035)
  • Abstract method getIdentifier() added to AccessTokenTrait. The trait cannot be used without the getIdentifier() method being defined (PR #1051)
  • An exception is now thrown if a refresh token is accidentally sent in place of an authorization code when using the Auth Code Grant (PR #1057)
  • Can now send access token request without being forced to specify a redirect URI (PR #1096)
  • In the BearerTokenValidator, if an implementation is using PDO, there is a possibility that a RuntimeException will be thrown when checking if an access token is revoked. This scenario no longer incorrectly issues an exception with a hint mentioning an issue with JSON decoding. (PR #1107)

8.0.0 - released 2019-07-13

Added

  • Flag, requireCodeChallengeForPublicClients, used to reject public clients that do not provide a code challenge for the Auth Code Grant; use AuthCodeGrant::disableRequireCodeCallengeForPublicClients() to turn off this requirement (PR #938)
  • Public clients can now use the Auth Code Grant (PR #938)
  • isConfidential getter added to ClientEntity to identify type of client (PR #938)
  • Function validateClient() added to validate clients which was previously performed by the getClientEntity() function (PR #938)
  • Add a new function to the AbstractGrant class called getClientEntityOrFail(). This is a wrapper around the getClientEntity() function that ensures we emit and throw an exception if the repo doesn't return a client entity. (PR #1010)

Changed

  • Replace convertToJWT() interface with a more generic __toString() to improve extensibility; AccessTokenEntityInterface now requires setPrivateKey(CryptKey $privateKey) so __toString() has everything it needs to work (PR #874)
  • The invalidClient() function accepts a PSR-7 compliant $serverRequest argument to avoid accessing the $_SERVER global variable and improve testing (PR #899)
  • issueAccessToken() in the Abstract Grant no longer sets access token client, user ID or scopes. These values should already have been set when calling getNewToken() (PR #919)
  • No longer need to enable PKCE with enableCodeExchangeProof flag. Any client sending a code challenge will initiate PKCE checks. (PR #938)
  • Function getClientEntity() no longer performs client validation (PR #938)
  • Password Grant now returns an invalid_grant error instead of invalid_credentials if a user cannot be validated (PR #967)
  • Use DateTimeImmutable() instead of DateTime(), time() instead of (new DateTime())->getTimeStamp(), and DateTime::getTimeStamp() instead of DateTime::format('U') (PR #963)

Removed

  • enableCodeExchangeProof flag (PR #938)
  • Support for PHP 7.0 (PR #1014)
  • Remove JTI claim from JWT header (PR #1031)

7.4.0 - released 2019-05-05

7.3.3 - released 2019-03-29

Added

  • Added error_description to the error payload to improve standards compliance. The contents of this are copied from the existing message value. (PR #1006)

7.3.2 - released 2018-11-21

Fixed

7.3.1 - released 2018-11-15

Fixed

  • Fix issue with previous release where interface had changed for the AuthorizationServer. Reverted to the previous interface while maintaining functionality changes (PR #970)

7.3.0 - released 2018-11-13

Changed

  • Moved the finalizeScopes() call from validateAuthorizationRequest method to the completeAuthorizationRequest method so it is called just before the access token is issued (PR #923)

Added

  • Added a ScopeTrait to provide an implementation for jsonSerialize (PR #952)
  • Ability to nest exceptions (PR #965)

Fixed

  • Fix issue where AuthorizationServer is not stateless as ResponseType could store state of a previous request (PR #960)

7.2.0 - released 2018-06-23

Changed

  • Added newvalidateRedirectUri method AbstractGrant to remove three instances of code duplication (PR #912)
  • Allow 640 as a crypt key file permission (PR #917)

Added

Changed

  • Changed hint for unsupportedGrantType exception so it no longer references the grant type parameter which isn't always expected (PR #893)
  • Upgrade PHPStan checks to level 7 (PR #856)

Added

  • Added event emitters for issued access and refresh tokens (PR #860)

  • Add Zend Diactoros library dependency to examples (PR #678)
  • Can set default scope for the authorization endpoint. If no scope is passed during an authorization request, the default scope will be used if set. If not, the server will issue an invalid scope exception (PR #811)
