AI Analysis
Technical Summary
CVE-2026-76855 is a sensitive information disclosure vulnerability in Netcore NR255-V version 1.5.130703. The flaw exists in audit endpoints managed by l7_web_auth_log_dump_cgi.c, audit_get_cgi.c, and mod_dispatch_auth/plan.json, which can be queried by attackers to obtain session and browsing history data of other users across sessions. This vulnerability allows unauthorized access to private personal information without requiring user interaction or elevated privileges beyond low privileges.
Potential Impact
An attacker with low privileges can remotely access sensitive personal information, including session and browsing history data of other users, by exploiting audit endpoints. This exposure compromises user privacy and could facilitate further targeted attacks or surveillance.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch information is currently available. Until a patch is released, restrict access to audit endpoints and monitor for unauthorized queries if possible.
