| Title | Linux Mint Xreader 4.6.3 Path Traversal |
|---|
| Description | A path traversal vulnerability in Linux Mint Xreader 4.6.3 allows an attacker to read arbitrary local files accessible to the user running Xreader. Crafted EPUB files can contain directory traversal sequences in OPF manifest or navigation href values. These paths are concatenated with the document directory without sufficient validation, allowing the resulting path to escape the EPUB extraction directory. Exploitation requires the victim to open a crafted EPUB file.
