No CVSS score has been assigned to CVE-2025-58438 yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by CVE-2025-58438?

CVE-2025-58438 affects the following packages: internetarchive (PyPI). Ecosystems affected: PyPI.

How do I fix CVE-2025-58438?

Update internetarchive to 5.5.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-58438 is resolved across your whole dependency graph.

How do I detect CVE-2025-58438 in my PyPI dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for internetarchive. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

How do I mitigate CVE-2025-58438 if there is no patch (or I can't update yet)?

If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

How does O3 Security protect against CVE-2025-58438?

O3 pinpoints whether CVE-2025-58438 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is CVE-2025-58438 actively exploited in the wild?

No public exploit code has been indexed for CVE-2025-58438 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for CVE-2025-58438?

CVE-2025-58438 has an EPSS (Exploit Prediction Scoring System) score of 1.4%, placing it in the 69th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is CVE-2025-58438?

CVE-2025-58438 is classified as Path Traversal (CWE-22). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

When was CVE-2025-58438 published, and has it been updated?

CVE-2025-58438 was published on September 6, 2025 and was last updated on April 10, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects PyPI packages — download data is not available via public APIs for these ecosystems.

Description

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.
