How severe is GHSA-8g68-2hcj-h8vg?

No CVSS score has been assigned to GHSA-8g68-2hcj-h8vg yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by GHSA-8g68-2hcj-h8vg?

GHSA-8g68-2hcj-h8vg affects the following packages: horizon (PyPI). Ecosystems affected: PyPI.

How do I fix GHSA-8g68-2hcj-h8vg?

Update horizon to 8.0.0a0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-8g68-2hcj-h8vg is resolved across your whole dependency graph.

How do I detect GHSA-8g68-2hcj-h8vg in my PyPI dependencies?

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

How do I mitigate GHSA-8g68-2hcj-h8vg if there is no patch (or I can't update yet)?

Escape or sanitise the affected output on the server side rather than relying on client-side filtering, and add a Content-Security-Policy that blocks inline script execution so injected markup cannot run even if it reaches the page.

Is GHSA-8g68-2hcj-h8vg actively exploited in the wild?

Yes. There are 1 known exploit references for GHSA-8g68-2hcj-h8vg, 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-8g68-2hcj-h8vg?

GHSA-8g68-2hcj-h8vg has an EPSS (Exploit Prediction Scoring System) score of 2.1%, placing it in the 82th 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-8g68-2hcj-h8vg?

GHSA-8g68-2hcj-h8vg 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-8g68-2hcj-h8vg published, and has it been updated?

GHSA-8g68-2hcj-h8vg was published on May 13, 2022 and was last updated on July 6, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Fixing This On Your OS

If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.
