Description

Affected Stackable version

25.7

Affected Apache NiFi version

2.4.0

Current and expected behavior

When the Stackable NiFi operator takes a parameter value and uses it in one of its XML-based configuration files it does not escape reserved characters. This means that if the value contains a character such as an ampersand (&) then the result is malformed XML document that cannot be parsed, causing NiFi to fail on startup.

Possible solution

The operator should escape any reserved characters when it includes a parameter value e.g. replacing & with &.

Research direction

Locate the code that renders XML-based configuration from parameter values, then reproduce the failure with an ampersand or another reserved character. Confirm that the generated configuration remains valid XML and that NiFi can start successfully with the escaped value.
