CVE-2024-34089Network attack vector

Stored XSS via trusted data-store injection

Published May 6, 2024 · Updated Mar 28, 2025

Stored XSS in Archer Platform 6 before 2024.04 allows remote authenticated users to execute script when victims view stored data. The platform accepts attacker-supplied HTML or JavaScript into a trusted application data store and later serves that content for browser execution. Exploitation requires an Archer account and victim interaction; public records do not identify the affected field or missing validation or output-encoding operation.
