Data modification via unsanitized URI path conversion
Published Jul 18, 2023 · Updated May 28, 2026
Path handling in affected Oracle Java SE and GraalVM releases allows remote attackers to alter data through exposed Libraries APIs. UnixUriUtils fails to sanitize slash-containing strings when converting URIs to file-system paths, permitting invalid Path objects that bypass Java sandbox restrictions. Exploitation requires an application, applet, or web service to supply untrusted data to the affected APIs; the reported consequence is limited to unauthorized updates, inserts, or deletions of accessible data.
