CVE-2026-76855Network attack vector

Cross-session history disclosure via unrestricted audit queries

Published Sep 15, 2026 · Updated Sep 15, 2026

Information disclosure in Netcore NR255-V 1.5.130703 allows attackers to read other users' session and browsing history. The l7_web_auth_log_dump_cgi.c and audit_get_cgi.c handlers, exposed through mod_dispatch_auth/plan.json, return audit records without limiting results to the requesting session. Network access to the web management interface is required; the exposed records reveal cross-session activity but do not establish configuration changes or service interruption.
