How severe is GHSA-7hxc-f267-h5q7?

No CVSS score has been assigned to GHSA-7hxc-f267-h5q7 yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by GHSA-7hxc-f267-h5q7?

GHSA-7hxc-f267-h5q7 affects the following packages: craftcms/cms (Packagist), craftcms/cms (Packagist). Ecosystems affected: Packagist.

How do I fix GHSA-7hxc-f267-h5q7?

Update craftcms/cms to 5.10.6 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-7hxc-f267-h5q7 is resolved across your whole dependency graph.

How do I detect GHSA-7hxc-f267-h5q7 in my Packagist dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for craftcms/cms, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate GHSA-7hxc-f267-h5q7 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-7hxc-f267-h5q7 actively exploited in the wild?

No public exploit code has been indexed for GHSA-7hxc-f267-h5q7 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-7hxc-f267-h5q7?

GHSA-7hxc-f267-h5q7 has an EPSS (Exploit Prediction Scoring System) score of 0.2%, placing it in the 9th 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-7hxc-f267-h5q7?

GHSA-7hxc-f267-h5q7 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-7hxc-f267-h5q7 published, and has it been updated?

GHSA-7hxc-f267-h5q7 was published on August 6, 2026 and was last updated on September 1, 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

The ensurePathIsContained function of the Local file system class is theoretically vulnerable to path traversal, although no exploitable scenario has been discovered.

When a file is read, an Asset object uses the getFileStream method of the Volume where the asset file is stored, which in turn uses the getFileStream method of the file system class used by that Volume. For the Local file system, this function returns a stream to a file on the local disk after verifying and creating the correct file path.

The file path is constructed by first validating the path and then adding a prefix to the validated and normalized path. The prefix is the path to the local directory that houses the particular volume. The order of operations matters here: first, a validation step, afterward a normalization step, and finally the construction of the resulting file path. This opens the possibility of a desanitization-style vulnerability, where the normalization invalidates the assumptions made by the validation or sanitization that preceded it.

Impact

The issue is not directly exploitable, but for hardening, a fix is recommended regardless.
