CVE-2025-29847Network attack vectorHinoki check available

Arbitrary file read via repeated URL encoding

Published Jan 19, 2026 · Updated Jan 19, 2026

Path traversal in Apache Linkis 1.3.0 through 1.7.0 allows remote attackers to read system files through crafted JDBC URL parameters. The JDBC engine and data source path checks a frontend-supplied connection URL before fully decoding repeated percent encoding, so a multiply encoded file path bypasses validation and reaches JDBC processing. No Linkis authentication is required, but JDBC engine or data source functionality must be reachable; exposure is limited to files readable by the Linkis service account.
