SCA: security update for org.apache.cxf:cxf-rt-rs-security-oauth2 (GHSA-542g-m3fx-q86f)

medium Tenable Self-Hosted Container Security Plugin ID 446165

Description

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

 - An authentication bypass vulnerability exists in the OAuth2 TokenIntrospectionService in Apache CXF. Due
 to a missing 'throw' keyword in the security context check, the introspection endpoint
 (/services/oauth2/introspect) can be accessed by any unauthenticated network attacker. However note that
 this is a safeguard only in the case that someone forgot to enable authentication on the service. Users
 are recommended to upgrade to version 4.2.2 or 4.1.7 or 3.6.12, which fixes this issue. (CVE-2026-50623)

Solution

Update the org.apache.cxf:cxf-rt-rs-security-oauth2 library and its related packages to version 4.1.7 or later.
