CVE-2022-21434Network attack vector

Unauthenticated data modification through unspecified Libraries flaw

Published Apr 19, 2022 · Updated Aug 3, 2024

Library flaw in Oracle Java SE 7u331, 8u321, 11.0.14, 17.0.2, and 18 allows remote attackers to modify accessible data. Oracle identifies only the Libraries component and has not published the flawed function or operation on untrusted input. Reachability requires sandboxed untrusted Java code or an application, such as a web service, that supplies attacker-controlled data to the affected APIs.
