CVE-2022-23551 affects Azure AD Pod Identity, a deprecated component for assigning Azure AD identities to Kubernetes applications. The vulnerability allows a malicious pod to bypass NMI validation by using a backslash in token requests, gaining unauthorized access to other identities. Rated Medium (CVSS 5.3), it requires high privileges and user interaction, potentially leading to limited confidentiality, high integrity, and limited availability impacts. There is no evidence of active exploitation, public exploit code, or significant community discussion, and it is not listed in CISA's KEV catalog.
