CVE-2022-45470Network attack vector

Unauthenticated information disclosure and cross-site scripting

Published Nov 21, 2022 · Updated Apr 29, 2025

Improper input validation in Apache Hama 0.7.1 and earlier allows remote attackers to disclose information through path traversal and XSS. Apache has not disclosed the affected endpoint, parameter, or code path, so the exact validation failure and XSS context remain unknown. No authentication or user interaction is required, and the published impact is limited to reading data rather than modification or service interruption.
