How do I fix GHSA-hx6g-q9v2-xh7v?

Update elgg/elgg to 3.3.23 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-hx6g-q9v2-xh7v is resolved across your whole dependency graph.

How do I detect GHSA-hx6g-q9v2-xh7v in my Packagist dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for elgg/elgg. 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-hx6g-q9v2-xh7v 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-hx6g-q9v2-xh7v?

O3 pinpoints whether GHSA-hx6g-q9v2-xh7v 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-hx6g-q9v2-xh7v actively exploited in the wild?

Yes. There are 1 known exploit references for GHSA-hx6g-q9v2-xh7v, 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-hx6g-q9v2-xh7v?

GHSA-hx6g-q9v2-xh7v has an EPSS (Exploit Prediction Scoring System) score of 1.6%, placing it in the 73th 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-hx6g-q9v2-xh7v?

GHSA-hx6g-q9v2-xh7v is classified as CWE-359 (CWE-359). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.
