CVE-2026-55847Public exploitNetwork attack vectorHinoki check available

Stored XSS via unescaped ANSI status rendering

Published Sep 14, 2026 · Updated Sep 14, 2026

Stored XSS in Allure Report before 2.39.0 allows attackers to execute JavaScript through crafted test-result status details. The ansi.js helper converts attacker-controlled statusMessage and statusTrace values with AnsiToHtml, then marks the output as a Handlebars SafeString without HTML escaping. Execution requires a viewer to open the affected status details; the script runs in the report origin and can read report data or compromise sessions bound to that origin.
