We got a HackerOne report by yox about a full path disclosure on OONI explorer error page:


This security vulnerability could potentially allow a malicious hacker to map an attack against internal systems. For example, if this were to be chained with another vulnerability such as path traversal; it may lead to compromise of internal systems.

Typically these sort of errors occur from incorrect data types, in this case it seems like it is just a simple 404 page which is however leaking too much information to the user.

A best practice method is to log these type of errors to a local text file, while showing the user a friendly 404 message. This is often achieved by disabling error reporting on the application side.
