Which packages are affected by GHSA-xpp7-j28w-2gvx?

Affected package information for GHSA-xpp7-j28w-2gvx is not yet fully mapped. Check the official advisory links for details.

How do I fix GHSA-xpp7-j28w-2gvx?

Upgrade the affected component to the fixed release for GHSA-xpp7-j28w-2gvx, or apply your distribution's backported patch — distro builds are often patched at an older version number, so check your vendor's advisory rather than the upstream version alone.

How do I detect GHSA-xpp7-j28w-2gvx in my code and dependencies?

Identify every host running the affected component and compare the installed build against the fixed version below — for source-built or distro-packaged software the version string, not a lockfile, is the source of truth (`dpkg -l`, `rpm -q`, or the binary's own `--version`).

How do I mitigate GHSA-xpp7-j28w-2gvx if there is no patch (or I can't update yet)?

Resolve every user-supplied path to its canonical form and reject anything that escapes the intended directory, and run the component under an account that has no read or write access outside the directory it legitimately serves.

Is GHSA-xpp7-j28w-2gvx actively exploited in the wild?

No public exploit code has been indexed for GHSA-xpp7-j28w-2gvx 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 GHSA-xpp7-j28w-2gvx?

GHSA-xpp7-j28w-2gvx has an EPSS (Exploit Prediction Scoring System) score of 0.5%, placing it in the 38th 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 GHSA-xpp7-j28w-2gvx?

GHSA-xpp7-j28w-2gvx 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 GHSA-xpp7-j28w-2gvx published, and has it been updated?

GHSA-xpp7-j28w-2gvx was published on September 15, 2026 and was last updated on September 18, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

crawl4ai before 0.9.3 contains an arbitrary file write vulnerability in PDFContentScrapingStrategy where the _filter_untrusted_fields function fails to validate untrusted configuration fields. Attackers can submit crafted config bodies with malicious image_save_dir paths to write attacker-controlled bytes into any directory accessible to the service account.

Fix
Upgrade the affected component to the fixed release for GHSA-xpp7-j28w-2gvx, or apply your distribution's backported patch — distro builds are often patched at an older version number, so check your vendor's advisory rather than the upstream version alone.
Workarounds
Resolve every user-supplied path to its canonical form and reject anything that escapes the intended directory, and run the component under an account that has no read or write access outside the directory it legitimately serves.
