CVE-2023-24997Network attack vector

JDBC parameter-filter bypass via nested URL encoding

Published Feb 1, 2023 · Updated Mar 26, 2025

Insufficient URL decoding in Apache InLong 1.1.0 through 1.5.0 allows remote attackers to bypass MySQL JDBC parameter filtering. MySQLSinkDTO.filterSensitive decodes a submitted JDBC URL only once before checking sensitive parameter names, so nested percent-encoding hides them from the filter. The crafted URL must reach the InLong Manager MySQL sink path; published vendor material does not identify a narrower resulting attacker action.
