CVE-2023-22051Network attack vector

Unauthenticated data disclosure via undisclosed compiler flaw

Published Jul 18, 2023 · Updated Sep 13, 2024

An unspecified flaw in the GraalVM Compiler in Oracle GraalVM releases allows remote attackers to read a subset of accessible data. Oracle has not disclosed the compiler locus or the operation that mishandles untrusted input. Exploitation is unauthenticated over multiple protocols but requires high attack complexity; affected releases are GraalVM Enterprise Edition 21.3.6 and 22.3.2 and GraalVM for JDK 17.0.7 and 20.0.1.
