Unauthenticated modification of accessible data
Published Jul 21, 2026 · Updated Jul 21, 2026
An ImageIO flaw in Oracle Java SE and GraalVM releases allows remote attackers to modify accessible data through crafted API input. Oracle identifies the ImageIO component but has not published the affected function, input format, or incorrect operation, so the underlying mechanism remains undisclosed. Exploitation requires a high-complexity path that supplies attacker-controlled data to ImageIO APIs through a service or untrusted sandboxed Java code, and the reported consequence is limited to unauthorized data changes.
