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.","published":"2026-08-12T14:14:27.030Z","modified":"2026-08-14T04:03:34.229425996Z","cvss":{"score":5.4,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"PyPI","name":"prowler","fixedVersion":"5.37.0"},{"ecosystem":"PyPI","name":"prowler-cloud","fixedVersion":"5.37.0"}],"fix":{"url":"https://github.com/prowler-cloud/prowler/commit/6db407ed3c17d4c73a8f619fdb30580c8465027f","label":"prowler-cloud/prowler@6db407e"},"references":[{"type":"WEB","url":"https://github.com/prowler-cloud/prowler/releases/tag/5.37.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/73xxx/CVE-2026-73262.json"},{"type":"ADVISORY","url":"https://github.com/prowler-cloud/prowler/security/advisories/GHSA-c2jg-2778-ggm4"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-73262"},{"type":"FIX","url":"https://github.com/prowler-cloud/prowler/commit/6db407ed3c17d4c73a8f619fdb30580c8465027f"},{"type":"FIX","url":"https://github.com/prowler-cloud/prowler/pull/12221"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-14T04:03:34.229425996Z"}}
