04/03/2024
- when an expression is configured for OIDCUnAuthAction (i.e. in the 2nd argument), also apply
it to OIDCUnAutzAction so that it can be used to enable step-up authentication for SPAs with
non-conformant browsers (some versions of Safari) and in (potentially insecure) iframes
see #1205; thanks @ryanwilliamnicholls
04/02/2024

03/29/2024
- fix OIDCUserInfoRefreshInterval, interval seconds would be interpreted as microseconds
03/14/2024

avoid refreshing userinfo on each request until access token expiry
- store interval as JSON integer in session
- use SameSite=Lax when OIDCCookieSameSite is On (also by default) instead of
Strict as overriding from Lax to Strict does not work reliably anymore (Chrome)

03/01/2024
- accept strings as well as integers in the "expires_in" claim from the token endpoint
- fix for "expires_in" string values returned from the token endpoint that would be interpreted as 0
this fixes using OIDCRefreshAccessTokenBeforeExpiry or OIDCUserInfoRefreshInterval with (older)
Azure AD configs that would result in a token refresh on every request since 2.4.15 or a 401 in 2.4.14.4
- fix setting the "exp" claim in userinfo signed JWTs (exp would be now+0) when no expires_in is returned
by the OP
- fix signed JWT caching when ttl set to 0 or "" which should apply the exp claim as the cache ttl
02/29/2024
- hash the cache key if it is larger than 512 bytes so large cache key entries (i.e. for JWT tokens)
are no longer a problem in unencrypted SHM cache configs, i.e. the default shared memory cache setup;
see issues/discussions on "could not construct cache key since key size is too large"
this is relevant for OAuth 2.0 RS configs with JWT access tokens and OpenID Connect RP
configs where OIDCRefreshAccessTokenBeforeExpiry/OIDCUserInfoRefreshInterval is set and
a JWT refresh token is returned

02/12/2024
- set Redis default retry interval time to 300 milliseconds (instead of 0.5ms) and make it configurable
- rewrite handling of parallel refresh token grant requests
- temporarily cache the results of the refresh token grant for other (almost) parallel callers
- fixes handing on the same server, and improves clustered handling through a best-effort distributed cached lock
- improves handling of non-rollover refresh tokens since it avoids unnecessary repeated calls to
the token endpoint, unnecessary token issuance and possibly corruption because different tokens "live"
temporarily in the same (conceptual) session in parallel before the session is stored (and the last one wins)
- bump to 2.4.15.3dev
02/06/2024
- CVE-2024-24814: prevent DoS when `OIDCSessionType client-cookie` is set and a crafted Cookie header is supplied

- use only the User-Agent header as input for the state browser fingerprinting by default (no X-Forwarded-For)
as cloud environments increasingly use dynamic proxy IPs in front
- use PKCE S256 by default; disable by configuring "OIDCPKCEMethod none"
- use SameSite cookies Strict by default; disable by configuring "OIDCCookieSameSite Off"
10/30/2023
- do not apply logout_on_error and authenticate_on_error when a parallel refresh token request is detected

"cache destroy function failed" error messages
- bump to 2.4.14rc8
04/16/2023

oidc_session_decode: could not verify secure JWT: cache value possibly corrupted
https://github.com/OpenIDC/mod_auth_openidc/pull/1047
- add option to strip the AES GCM header from encrypted state/session JWTs with env var OIDC_JWT_STRIP_HDR=true
- bump to 2.4.14rc6
04/11/2023
- add caching of signed userinfo JWTs; default cache time is set to the "exp" claim, can be configured/disabled with:
SetEnvIfExpr true "OIDC_USERINFO_SIGNED_JWT_CACHE_TTL=0"
be careful when setting "jti", "nbf", "iat" and" "exp" claims in the OIDCUserInfoClaimsExpr filter since they may
overload the cache with entries per-user/per-timestamp if the result differs from the previous request
- bump to 2.4.14rc5
04/11/2023
- add OIDCFilterClaimsExpr that allows for processing claims in the both the id_token and claims from the
userinfo endpoint before storing them in the session, after applying (optional) blacklisting/whitelisting
on the toplevel keys; only available when compiled/linked with libjq
- fix memory access error using default value for OIDCPassUserInfoAs
- bump to 2.4.14rc4
04/10/2023
- add support for OIDCUserInfoClaimsExpr that allows for processing claims returned from the userinfo
endpoint with a JQ-based expression before propagating them according to OIDCPassUserInfoAs claims|json|signed_jwt
(ie. does not work for "OIDCPassUserInfoAs jwt"), and is only available when compiled/linked with libjq
- allow OIDCPassUserInfoAs directive in Location/Directory contexts
- fix memory leak when using JQ-based expressions in "Require claims_expr"
- bump to 2.4.14rc3
04/09/2023
- make sure mod_auth_openidc runs before mod_proxy so calls to the redirect URI are never proxied
and no separate Location directive or ProxyPass exception for OIDCRedirectURI is required (anymore)
- handle discovery in the content handler so regular Apache processing applies to the HTTP/HTML response
- bump to 2.4.14rc2
04/09/2023
- return 40x instead of 200 on all (authorization) error responses
- correct backwards compatibility with <2.4.14 for state mismatch/timeout handling
- bump to 2.4.14rc1
04/07/2023
- deprecate OIDCHTMLErrorTemplate and rely on standard Apache error handling capabilities by default
environment variable strings REDIRECT_OIDC_ERROR and REDIRECT_OIDC_ERROR_DESC are available in ErrorDocument
backwards compatibility is retained by setting "OIDCHTMLErrorTemplate deprecated"
- bump to 2.4.14rc0
04/07/2023
- add support for passing on claims resolved from the userinfo endpoint in a JWT signed by
mod_auth_openidc using `OIDCPassUserInfoAs signed_jwt[:<name>]` with the keys configured
in OIDCPrivateKeyFiles/OIDCPublicKeyFiles
- add support for overriding the default header/environment variable names in
`OIDCPassUserInfoAs json:<name>` (default: "OIDC_userinfo_json")
and
`OIDCPassUserInfoAs jwt:<name>` (default: "OIDC_userinfo_jwt")
- bump to 2.4.13.3rc3
04/06/2023
- merge client_signing_keys and client_encryption_keys into client_keys
since we detect the usage type correctly now

OIDCPublicKeyFiles, OIDCPrivateKeyFiles, OIDCProviderVerifyCertFiles, OIDCOAuthVerifySharedKeys and OIDCOAuthVerifyCertFiles
by using the prefix "sig:" or "enc:" in the value; using this in OIDCPublicKeyFiles also
publishes separate "use: sig" and/or "use: enc" keys on the client jwks_uri <redirect_uri>?jwks=rsa
- fix: don't immediately refresh of JWKs from (signed)_jwks_uri if "kid" was not set in JWT, but try the cache first
- fix: properly respect "use" attribute (sig/enc) in signing, verification and encryption
- bump to 2.4.13.3rc1
04/03/2023
- generate Elliptic Curve "kid" using curve identifier with htonl in network byte order
so "make check" works on big endian platforms

https://github.com/OpenIDC/mod_auth_openidc/security/advisories/GHSA-f5xw-rvfr-24qr
- replace apr_strnatcmp/strcmp with _oidc_strcmp and replace strncmp with _oidc_strncmp
- handle OpenSSL initialization in new oidc_pre_config_init function:
this allows omitting "kid" in OIDCPublicKeyFiles (ao.) when linked against OpenSSL 1.0.x
03/27/2023
- fix code scanning alerts
- bump to 2.4.13.2rc2
03/24/2023
