Rust has Critical Stored XSS in Preview Modal, leading to Administrative Account Takeover

Published Feb 25, 2026 · Updated Feb 25, 2026 · Assigned by GitHub_M

Description

RustFS is a distributed object storage system built in Rust. Prior to version 1.0.0-alpha.83, a Stored Cross-Site Scripting (XSS) vulnerability in the RustFS Console allows an attacker to execute arbitrary JavaScript in the context of the management console. By bypassing the PDF preview logic, an attacker can steal administrator credentials from `localStorage`, leading to full account takeover and system compromise. Version 1.0.0-alpha.83 fixes the issue.
