CVE-2024-21211Network attack vector

Unauthorized data modification via undisclosed compiler flaw

Published Oct 15, 2024 · Updated Oct 31, 2024

A compiler flaw in Oracle Java SE 23 and affected GraalVM releases allows remote attackers to modify accessible data via untrusted input. Oracle has not published the faulty compiler routine or the wrong operation it performs on that input. Reachability requires compiler API exposure, such as a web service, or sandboxed execution of untrusted Java code; reported impact is limited to data updates, insertions, or deletions.
