Which packages are affected by GHSA-3x96-m42v-hvh5?

GHSA-3x96-m42v-hvh5 affects the following packages: microweber/microweber (Packagist). Ecosystems affected: Packagist.

How do I fix GHSA-3x96-m42v-hvh5?

Update microweber/microweber to 1.2.18 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-3x96-m42v-hvh5 is resolved across your whole dependency graph.

How do I detect GHSA-3x96-m42v-hvh5 in my Packagist dependencies?

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

How do I mitigate GHSA-3x96-m42v-hvh5 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-3x96-m42v-hvh5 actively exploited in the wild?

Yes. There are 1 known exploit references for GHSA-3x96-m42v-hvh5, 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-3x96-m42v-hvh5?

GHSA-3x96-m42v-hvh5 has an EPSS (Exploit Prediction Scoring System) score of 2.6%, placing it in the 86th 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-3x96-m42v-hvh5?

GHSA-3x96-m42v-hvh5 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.

Is there exploit tooling available for GHSA-3x96-m42v-hvh5?

A Nuclei detection template exists for GHSA-3x96-m42v-hvh5, meaning automated scanners can fingerprint it. Public exploit tooling significantly increases real-world risk — prioritize patching and ensure detection coverage. Exploit tooling should only ever be used in isolated, authorized testing environments.

When was GHSA-3x96-m42v-hvh5 published, and has it been updated?

GHSA-3x96-m42v-hvh5 was published on June 23, 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.
