CVE-2023-22091Network attack vector

Data disclosure and modification via compiler flaw

Published Oct 17, 2023 · Updated Sep 13, 2024

Compiler vulnerability in Oracle GraalVM Enterprise Edition 20.3.11, 21.3.7, and 22.3.3 allows remote attackers to read and modify data. Oracle identifies the affected locus only as the Compiler component and has not disclosed the erroneous operation or triggering input. Exploitation requires unauthenticated network access through one of multiple protocols and high attack complexity; impact is limited to a subset of accessible data.
