Which packages are affected by GHSA-3h7r-4xxj-3mfm?

GHSA-3h7r-4xxj-3mfm affects the following packages: com.liferay:com.liferay.frontend.editor.ckeditor.web (Maven), com.liferay:com.liferay.frontend.js.dependencies.web (Maven), liferay-ckeditor (npm). Ecosystems affected: Maven, npm.

How do I fix GHSA-3h7r-4xxj-3mfm?

Update com.liferay:com.liferay.frontend.editor.ckeditor.web to 5.0.107 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-3h7r-4xxj-3mfm is resolved across your whole dependency graph.

How do I detect GHSA-3h7r-4xxj-3mfm in my Maven, npm dependencies?

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

How do I mitigate GHSA-3h7r-4xxj-3mfm 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-3h7r-4xxj-3mfm?

O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-3h7r-4xxj-3mfm can be triaged on real exposure rather than presence alone.

Is GHSA-3h7r-4xxj-3mfm actively exploited in the wild?

No public exploit code has been indexed for GHSA-3h7r-4xxj-3mfm 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-3h7r-4xxj-3mfm?

GHSA-3h7r-4xxj-3mfm 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-3h7r-4xxj-3mfm?

GHSA-3h7r-4xxj-3mfm 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-3h7r-4xxj-3mfm published, and has it been updated?

GHSA-3h7r-4xxj-3mfm was published on August 22, 2025 and was last updated on August 25, 2025. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.
