BigTree 4.3 allows full path disclosure via authenticated admin/news/ input that triggers a syntax error.

LOW 2.7EPSS 0.82%

Does this matter?

Lower severity and a low EPSS score (0.82%). Track it; it rarely justifies an emergency change on its own.

Description

BigTree 4.3 allows full path disclosure via authenticated admin/news/ input that triggers a syntax error. NOTE: This has been disputed with the following reasoning: "The issue reported requires full developer level access to the content management system where cross site scripting is not an issue -- you already have full control of the CMS including running arbitrary PHP.
