CVE-2026-11493Public exploit

Weak password enforcement for Samba file sharing

Published Jun 8, 2026 · Updated Jun 8, 2026

Weak password requirements in Tenda AC15 15.03.05.19 allow remote attackers on the local network to weaken Samba file-share authentication. The public record identifies /etc_ro/smb.conf as the locus but does not disclose the affected directive or how untrusted input changes password enforcement. Reachability requires adjacent-network access and high-complexity manipulation; the reported consequence is weaker authentication for router-hosted file shares.
