Which packages are affected by GHSA-h6wm-mr85-4h9g?

GHSA-h6wm-mr85-4h9g affects the following packages: facturascripts/facturascripts (Packagist). Ecosystems affected: Packagist.

How do I fix GHSA-h6wm-mr85-4h9g?

Update facturascripts/facturascripts to 2022.06 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-h6wm-mr85-4h9g is resolved across your whole dependency graph.

How do I detect GHSA-h6wm-mr85-4h9g in my Packagist dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for facturascripts/facturascripts. 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 GHSA-h6wm-mr85-4h9g 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 GHSA-h6wm-mr85-4h9g?

O3 pinpoints whether GHSA-h6wm-mr85-4h9g 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 GHSA-h6wm-mr85-4h9g actively exploited in the wild?

Yes. There are 1 known exploit references for GHSA-h6wm-mr85-4h9g, including 1 in-the-wild exploitation observed on GitHub and other sources. Treat this as actively exploitable and prioritize patching immediately. All exploit code should only be run in an isolated sandbox environment for research or authorized testing — never against production systems without explicit written authorization.

What is the EPSS score for GHSA-h6wm-mr85-4h9g?

GHSA-h6wm-mr85-4h9g has an EPSS (Exploit Prediction Scoring System) score of 0.9%, placing it in the 55th 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-h6wm-mr85-4h9g?

GHSA-h6wm-mr85-4h9g is classified as Cross-site Scripting (XSS) (CWE-79). 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-h6wm-mr85-4h9g published, and has it been updated?

GHSA-h6wm-mr85-4h9g was published on June 14, 2022 and was last updated on November 8, 2023. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.
