CVE-2026-2562Public exploitNetwork attack vector

Remote privilege escalation via crafted File argument

Published Feb 16, 2026 · Updated Feb 16, 2026

Improper privilege management in JD Cloud Box AX6600 4.5.1.r4533 allows remote authenticated users to escalate privileges via /jdcapi. The jdcweb_rpc cast_streen function mishandles an attacker-controlled File argument, but the public record does not disclose the exact unsafe operation. Low-privilege access and no user interaction are required; successful exploitation affects device confidentiality, integrity, and availability.
