SCA: security update for org.keycloak:keycloak-services (GHSA-rp95-xpg9-c2cq)

high Tenable Cloud Security Plugin ID 442646

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - A flaw was found in Keycloak's URL validation logic during redirect operations. By crafting a malicious
 request, an attacker could bypass validation to redirect users to unauthorized URLs, potentially leading
 to the exposure of sensitive information within the domain or facilitating further attacks. This
 vulnerability specifically affects Keycloak clients configured with a wildcard (*) in the "Valid Redirect
 URIs" field and requires user interaction to be successfully exploited. The issue stems from a discrepancy
 in how Keycloak and the underlying Java URI implementation handle the user-info component of a URL. If a
 malicious redirect URL is constructed using multiple @ characters in the user-info section, Java's URI
 parser fails to extract the user-info, leaving only the raw authority field. Consequently, Keycloak's
 validation check fails to detect the malformed user-info, falls back to a wildcard comparison, and
 incorrectly permits the malicious redirect. (CVE-2026-7504)

Solution

Update the org.keycloak:keycloak-services library and its related packages to version 26.6.2 or later.
