CVE-2025-70058Network attack vector

HTTPS interception via disabled certificate validation

Published Feb 23, 2026 · Updated Feb 23, 2026

Improper certificate validation in YMFE yapi 1.12.0 and earlier allows man-in-the-middle attackers to read or alter HTTPS traffic. The httpRequestByNode function passes rejectUnauthorized false to a new HTTPS agent for every Axios request, accepting untrusted server certificates. Exploitation requires a network position between the YApi server and its HTTPS destination; it exposes or permits modification of data carried by those outbound requests.
