Prowler: Stored XSS in HTML reports through unescaped cloud resource tags

Published Aug 12, 2026 · Updated Aug 12, 2026 · Assigned by GitHub_M

Description

Prowler is a cloud security platform. Prior to 5.37.0, Prowler's HTML output formatter in prowler/lib/outputs/html/html.py inserted finding.resource_tags, assembled by unroll_dict and parse_html_string, into generated reports without HTML escaping, allowing a cloud principal who can modify a scanned resource tag to store HTML or JavaScript that executes when another user opens the report. This issue is fixed in version 5.37.0.
