Official Description

SSCMS v7.4.0 contains a reflected cross-site scripting vulnerability in the STL processing endpoint that allows attackers to execute arbitrary JavaScript by crafting malicious STL template payloads that are decrypted and returned without proper sanitization.

Technical Analysis

CVE-2026-7429 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
