How do I detect GHSA-g78h-pf65-46rv in my npm, Packagist dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for ckeditor-dev. 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-g78h-pf65-46rv 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-g78h-pf65-46rv?

O3 pinpoints whether GHSA-g78h-pf65-46rv 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-g78h-pf65-46rv actively exploited in the wild?

No public exploit code has been indexed for GHSA-g78h-pf65-46rv 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-g78h-pf65-46rv?

GHSA-g78h-pf65-46rv has an EPSS (Exploit Prediction Scoring System) score of 1.8%, placing it in the 75th 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.

When was GHSA-g78h-pf65-46rv published, and has it been updated?

GHSA-g78h-pf65-46rv was published on May 14, 2022 and was last updated on December 10, 2025. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

The Enhanced Image (aka image2) plugin for CKEditor in versions 4.5.10 through 4.9.1; fixed in 4.9.2, and as used in Drupal 8 before 8.4.7 and 8.5.x before 8.5.2 and other products, is vulnerable to cross-site scripting because it allows remote attackers to inject arbitrary web script through a crafted IMG element.
