CVE-2026-70907 is an easily exploitable vulnerability in the JSSE component of Oracle Java SE, Oracle GraalVM for JDK, and Oracle GraalVM Enterprise Edition. Affected versions are Oracle Java SE 8u501, 11.0.32, 17.0.20, 21.0.12, 25.0.4, and 26.0.2; Oracle GraalVM for JDK 17.0.20 and 21.0.12; and Oracle GraalVM Enterprise Edition 21.3.19. An unauthenticated attacker with network access via TLS can exploit the flaw by supplying crafted data to APIs in the affected component, such as through a web service. Successful exploitation can compromise the affected product's availability and cause a partial denial of service. The available information identifies the affected component as JSSE and characterizes the issue as a TLS server hardening deficiency, but does not provide sufficient technical detail to determine a precise root cause or vulnerable function.
