CVE-2026-2092 | BDVDB-2026-320960 Detail
Red HatRed Hat build of Keycloak 26.2
Description#
A flaw was found in Keycloak. Keycloak's Security Assertion Markup Language (SAML) broker endpoint does not properly validate encrypted assertions when the overall SAML response is not signed. An attacker with a valid signed SAML assertion can exploit this by crafting a malicious SAML response. This allows the attacker to inject an encrypted assertion for an arbitrary principal, leading to unauthorized access and potential information disclosure.
Impact#
Per CVSS v3.1: confidentiality impact high, integrity impact low, availability impact low. Attack vector: network.
Weaknesses#
- CWE-1287 Improper Validation of Specified Type of Input
