1.7.1 (2026-06-18)

Bug fixes:

• Send an explicit User-Agent header when fetching Keycloak's JWKS: PyJWT's PyJWKClient defaults to Python-urllib/<ver>, which the production Keycloak WAF rejects with 403 Forbidden, breaking Bearer-token verification. Each JWKS client is now built with User-Agent: pas.plugins.kimug. [bsuttor]

1.7.0 (2026-06-17)

New features:

• Remove pas.plugins.imio and authentic plugin [remdub]

• Restrict the SSO-apps user sync to members of an organisation-specific municipality group: get_keycloak_users_from_oidc_sso_apps now only imports access-group members that also belong to one of the groups listed in the SSO_APPS_MUNICIPALITY_GROUPS environment variable (e.g. [pl_belleville_ac]). When the variable is unset, all access-group members are imported as before. [remdub]

• Browser view (with run and dry-run buttons in the control panel) and thin scripts/set_sso_apps_permissions.py runscript to set roles on authentic sources from sso apps. [remdub]

Bug fixes:

• Fix sticky 403 Forbidden on token authentication: the JWKS signing-key client was a single class-level cache shared by both the oidc and sso-apps realms. A request would receive a client built for the other realm, whose kid is never in the cached keyset, forcing a live JWKS refetch on essentially every request. That fetch storm could trip the Keycloak proxy's rate-limiter into returning 403, and PyJWT clearing its keyset cache on each failed fetch kept it failing until a restart. JWKS clients are now cached per realm. [remdub]
• Add a per-realm JWKS failure backoff: after a failed signing-key fetch, further fetches for that realm are skipped for a short cooldown, so a transient 403 from the Keycloak proxy can no longer become a self-sustaining retry storm. Authentication for the realm recovers automatically once the endpoint is healthy again, without a restart. [remdub]

1.6.3 (2026-06-09)

Bug fixes:

• Fix auto-created SSO users having no email or name: _ensure_user_exists was reading Keycloak Admin-API field names (username, firstName, lastName, id) from the JWT, but tokens carry OIDC claim names (preferred_username, given_name, family_name, sub). User properties are now populated from the correct claims, and the {username}@kimug.be fallback works again. [remdub] ensure-user-claims

1.6.2 (2026-06-09)

Bug fixes:

• Don't crash startup when the pas.plugins.kimug.log registry record is missing on a not-yet-upgraded site. The set_oidc_settings subscriber now skips writing the record when it isn't registered, instead of raising InvalidParameterError and preventing the instance from booting. [remdub] log-record-boot-fix

1.6.1 (2026-06-08)

Bug fixes:

• Make the oidc plugin handle the interactive login challenge instead of oidc_sso_apps. The oidc_sso_apps plugin is now removed from IChallengePlugin (it only validates Bearer tokens), and upgrade step 1004→1005 fixes already-installed sites. [remdub] oidc-first-challenge

1.6.0 (2026-06-05)

New features:

• Refactor the control panel so SSO applications (apps) settings can be configured easily. [remdub] controlpanel-sso-apps

Bug fixes:

• Fix control panel action buttons (update OIDC settings, sync Keycloak users) being blocked by plone.protect CSRF protection, which aborted the transaction and redirected to the "Confirming User Action" page. The buttons now include a valid _authenticator token. [remdub] controlpanel-csrf

1.5.5 (2026-06-04)

New features:

• When creating a new user from an oidc_sso_apps token, missing email is defaulted to {username}@kimug.be and missing firstName/lastName are defaulted to {username} / "sso-apps". [remdub] sso-apps-user-defaults
• _decode_token for oidc_sso_apps now reads the JWT audience from SSO_APPS_AUDIENCE env var, falling back to SSO_APPS_CLIENT_ID and then "imio-apps-plone". [remdub] token-audience

1.5.4 (2026-06-04)

New features:

• Set log level to info for pas.plugins.kimug logger [remdub]

1.5.3 (2026-06-03)

New features:

• Add is_log_active utility function to check if plugin logging is enabled via the registry. [remdub] is-log-active

1.5.2 (2026-06-02)

New features:

• get_keycloak_users_from_oidc_sso_apps now includes SSO apps users that are missing optional fields: missing email is filled as {username}@kimug.be; missing first and last name are filled as the username and sso-apps respectively. [remdub] sso-apps-users-default-fields

1.5.1 (2026-06-02)

New features:

• Add upgrade step (1002→1003) that registers the oidc_sso_apps plugin, applies OIDC settings, and syncs SSO Apps users from Keycloak into Plone on existing instances. [remdub] upgrade-1003-oidc-sso-apps

1.5.0 (2026-05-29)

New features:

• Add SSO apps authentication via a second PAS plugin (oidc_sso_apps) backed by a dedicated sso-apps Keycloak realm. Bearer tokens are routed to the correct plugin by inspecting the iss claim; Plone users are created automatically on first access. A sync view (/keycloak_sso_apps_users) lets administrators bulk-import SSO app users. Configure via SSO_APPS_CLIENT_ID, SSO_APPS_CLIENT_SECRET, SSO_APPS_URL, SSO_APPS_ACCESS_GROUP. [remdub] sso-apps-authentication

Bug fixes:

• Security: Kimug bearer-token authentication now verifies JWT signatures against the Keycloak realm's JWKS with RS256, and checks iss, aud, exp, iat. Previously jwt.decode(..., options={"verify_signature": False}) accepted any JWT — including attacker-forged tokens — allowing account takeover by sending Authorization: Bearer <unsigned.jwt>. _decode_token now returns None on any verification failure instead of raising, so the PAS authentication chain degrades cleanly. Configure keycloak_url, keycloak_realm, keycloak_issuer and keycloak_audience via environment variables (audience defaults to account). [bsuttor] kimug-jwt-verify
