CVE-2025-27522Public exploitNetwork attack vector

Data exposure and modification via case-variant JDBC parameters

Published May 28, 2025 · Updated Jan 28, 2026

Deserialization in Apache InLong 1.13.0 through 2.1.0 allows remote attackers to bypass JDBC security checks via crafted connection URLs. InLong Manager's MySQLSensitiveUrlUtils.containSensitiveKey performs case-sensitive substring checks for dangerous parameters set to true or yes, so case-variant values evade filtering. No credentials or user interaction are required; successful exploitation can expose or modify data reachable through the Manager's JDBC processing.
