### Apache Hop version? 2.19.0 ### Java version? openjdk 21.0.2 2024-01-16 ### Operating system macOS ### What happened? A pipeline that declares its own named parameter (with a default value) can have that parameter silently overridden by an unrelated variable of the same name that happens to exist in the calling workflow's scope — even when the calling **Pipeline** action has "Pass parameter values to sub pipeline" **unchecked** and has no entry for that parameter in its Parameters grid at all. This contradicts the documented precedence rule and means two independently authored pipelines that happen to reuse a common parameter name (e.g. `my-param`, `input_file`, `date`) can silently cross-contaminate values through the shared workflow variable space. <img width="1385" height="1025" alt="Image" src="https://github.com/user-attachments/assets/31925c48-e02e-4b12-b277-268e525b8480"; /> Example added: [bug.zip](https://github.com/user-attachments/files/31409478/bug.zip) ### Issue Priority Priority: 2 ### Issue Component Component: Other -- This is an automated message from the Apache Git Service.
