CVE-2024-20954Network attack vector

Unauthenticated data disclosure via compiler flaw

Published Apr 16, 2024 · Updated Nov 25, 2024

Information disclosure in Oracle GraalVM's Compiler component allows remote attackers to read a subset of accessible data via multiple protocols. Oracle lists GraalVM for JDK 17.0.10, 21.0.2, and 22 and Enterprise Edition 20.3.13 and 21.3.9 as affected, but has not published the faulty compiler operation or triggering input. Exploitation requires no credentials or user interaction but has high attack complexity, and the reported consequence is limited to partial data disclosure.
