Affected: jjjake internetarchive

internetarchive is a Python and Command-Line Interface to Archive.org In versions 5.5.0 and below, there is a directory traversal (path traversal) vulnerability in the File.download() method of the internetarchive library. The file.download() method does not properly sanitize user-supplied filenames or validate the final download path. A maliciously crafted filename could contain path traversal sequences (e.g., ../../../../windows/system32/file.txt) or illegal characters that, when processed, would cause the file to be written outside of the intended target directory. An attacker could potentially overwrite critical system files or application configuration files, leading to a denial of service, privilege escalation, or remote code execution, depending on the context in which the library is used. The vulnerability is particularly critical for users on Windows systems, but all operating systems are affected. This issue is fixed in version 5.5.1.

Affected: PyPI: internetarchive

### Impact **What kind of vulnerability is it?** This is a **Critical** severity directory traversal (path traversal) vulnerability in the `File.download()` method of the `internetarchive` library.

**Who is impacted?** All users of the `internetarchive` library versions `< 5.5.1` are impacted. The vulnerability is particularly critical for users on **Windows systems**, but all operating systems are affected.

**Description of the vulnerability:** The vulnerability existed because the `file.download()` method did not properly sanitize user-supplied filenames or validate the final download path. A maliciously crafted filename could contain path traversal sequences (e.g., `../../../../windows/system32/file.txt`) or illegal characters that, when processed, would cause the file to be written outside of the intended target directory.

**Potential Impact:** An attacker could potentially overwrite critical system files or application configuration files, leading to a denial of service, privilege escalation, or remote code execution, depending on the context in which the library is used.

### Patches **Has the problem been patched?** Yes, the problem has been patched.

**What versions should users upgrade to?** Users must upgrade to version **5.5.1** or later.

### Workarounds Is there a way for users to fix or remediate the vulnerability without upgrading? There is no direct workaround that does not involve upgrading the library. The vulnerability is in the core logic of the file d…
