CVE-2023-22041

Critical data disclosure to sandboxed untrusted code

Published Jul 18, 2023 · Updated May 28, 2026

HotSpot in Oracle Java SE 8u371-perf, 11.0.19, 17.0.7, and 20.0.1 allows local users to read all accessible data. Oracle has not disclosed the flawed HotSpot operation or the untrusted input that triggers the sandbox compromise. Exploitation requires a deployment that runs untrusted sandboxed applet or Java Web Start code; deployments loading only trusted administrator-installed code are not affected.
