Technical description

Improper Authentication in the social account linking path of the Prowler API in Prowler from 5.4.0 before 5.35.0 allows a remote unauthenticated attacker to obtain persistent access to the account of a user who has not yet registered, because ProwlerSocialAccountAdapter.pre_social_login() in api/src/backend/api/adapters.py links a Google or GitHub login to any existing local account that has the same email address as the one returned by the provider, without requiring that the address has been verified by the provider or on the existing account, and without any other check that both accounts belong to the same person. Self registration is open and the new account is usable at once, because UserViewSet.get_permissions() in api/src/backend/api/v1/views.py grants AllowAny to the create action, ACCOUNT_EMAIL_VERIFICATION is set to none in api/src/backend/config/settings/social_login.py, and the Django ModelBackend checks only the password and is_active, not the django-allauth EmailAddress record. An attacker who registers an email address before its owner keeps the password set at registration after the link is made, because sociallogin.connect() does not reset the password and does not disable the existing account, and the owner who later signs in with Google or GitHub is logged into the attacker's account. django-allauth makes the same email based link on its own, because SOCIALACCOUNT_EMAIL_AUTHENTICATION and SOCIALACCOUNT_EMAIL_AUTHENTICATION_AUTO_CONNECT are both set to True in the same settings module. This gives the attacker the cloud provider credentials, scan findings and tenant memberships held in the account.

——0IBM i 7.3, 7.4, 7.5, and 7.6 could allow an unathenticated remote attacker to bypass security restrictions due to improper access control. By sending a specially crafted HTTP request to any URL within the Navigator application prior to authentication, a bad actor could exploit this vulnerability to alter server-side session security state.1d CVE-2026-1136827.4 HIG

——0Cruise Control's Jetty ConstraintSecurityHandler registers security constraints on exact path specs without a catch-all wildcard constraint and without calling setDenyUncoveredHttpMethods(true). The servlet routes requests using Path.of(pathInfo).getFileName(), which strips all leading segments and trailing slashes. Requests like POST /kafkacruisecontrol/x/rebalance bypass authentication entirely but still dispatch to admin endpoints. All 15 admin endpoints become reachable without authentication. In AMQ Streams, the Strimzi operator's NetworkPolicy restricts Cruise Control port 9090 to operator pods only, reducing effective severity to Important.2d CVE-2026-43844—
