CVE-2022-22969Network attack vector

Service interruption via session-bound request accumulation

Published Apr 21, 2022 · Updated Aug 3, 2024

Uncontrolled resource consumption in VMware Spring Security OAuth 2.5.1 and earlier allows remote authenticated users to interrupt service. The implementation accepts repeated Authorization Code Grant initiations in one session until system resources are exhausted; the vendor has not identified the accumulating object or exact code locus. A single authenticated session is sufficient, and only applications configured as OAuth 2.0 clients expose the affected flow.
