Identity security risks and social engineering tactics top today's threat updates. Organizations running Keycloak identity management servers face an urgent patching priority due to an authentication flaw that allows unauthenticated password resets.
Meanwhile, threat actors continue abusing user interactions with ClickFix social engineering schemes to deploy loaders and infostealers, while cyber espionage campaigns target government infrastructure with custom backdoors.
Critical Keycloak Password Reset Flaw Could Let Unauthenticated Attackers Take Over Any Account
Red Hat and Keycloak patched CVE-2026-18963, a critical improper state validation flaw in Keycloak's reset-credentials flow that allows unauthenticated remote attackers to force password resets and take over any account.
- Why it matters
- Unauthenticated attackers can gain full access to user and admin accounts on vulnerable open-source Keycloak or Red Hat build of Keycloak identity servers.
- What to do
- Update upstream Keycloak to version 26.7.2, or Red Hat build of Keycloak to 26.4.15 or 26.6.6.
