Traffic interception via disabled TLS certificate checks
Published Feb 23, 2026 · Updated Feb 23, 2026
Improper certificate validation in Ayms node-To master allows man-in-the-middle attackers to read and alter TLS traffic. The TLS socket options hard-code rejectUnauthorized to false, so Node.js accepts certificates that fail CA and hostname checks. An unauthenticated attacker must control the network path; successful interception exposes and permits modification of data carried by affected TLS connections.
