CVE-2024-21147Network attack vector

Unauthenticated access and modification of critical data

Published Jul 16, 2024 · Updated Feb 13, 2025

HotSpot access-control weakness in affected Oracle Java SE and GraalVM releases allows remote attackers to read and modify critical data. Oracle identifies the locus only as HotSpot and has not published the faulty operation or how untrusted input bypasses its access controls. Exploitation requires a high-complexity path that supplies untrusted data to affected APIs, such as through a web service or sandboxed Java client.
