Spring Data Relational Parameter not Escaped for Query By Example LIKE Pattern

MEDIUM | JUNE 09, 2026 | CVE-2026-41697

Description

Spring Data Relational does not properly escape binging values of externally-controlled input when using StringMatcher (STARTING, ENDING, or CONTAINING) in Query By Example (QBE).

If an application actively wires externally-controlled input into a QBE probe, an attacker can supply wildcard characters to perform boolean-based blind data inference, allowing them to guess data within the queried entity.

This vulnerability is not exploitable by default. It requires the application developer to explicitly configure and expose a QBE probe that accepts untrusted input.
