## Summary

GRR, a resource management and reservation application, is affected by this vulnerability. An administrator-level user can exploit the database restoration feature to read sensitive files or delete arbitrary files on the server, leading to information disclosure and denial of service.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- JeromeDevome GRR: fixed in 4.5.0

## Description

GRR is a resource management and reservation application. Prior to the advisory-reported fixed version 4.5.0, the database restoration feature fails to enforce or validate file paths. A user with administrator privileges can manipulate the input to read or delete arbitrary files on the server, causing sensitive file disclosure and denial of service through file deletion. The impact is amplified when the server runs with elevated privileges. The advisory reports this issue as fixed in version 4.5.0.
