CVE-2015-7546 describes a critical flaw in OpenStack Identity (Keystone) and keystonemiddleware, affecting versions prior to 2015.1.3 (Kilo) and 8.0.2 (Liberty), as well as Oracle implementations. This vulnerability allows authenticated users to bypass access restrictions and gain unauthorized access to cloud resources by manipulating revoked authorization tokens, specifically when using PKI or PKIZ token providers. With a CVSS score of 7.5 (High), the attack vector is network-based with high impact on confidentiality, integrity, and availability, though it requires high attack complexity and low privileges. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion, indicating a low current threat landscape.
