Which packages are affected by GHSA-96mh-7xpr-qcgw?

GHSA-96mh-7xpr-qcgw affects the following packages: rainlab/blog-plugin (Packagist). Ecosystems affected: Packagist.

How do I fix GHSA-96mh-7xpr-qcgw?

Update rainlab/blog-plugin to 1.4.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-96mh-7xpr-qcgw is resolved across your whole dependency graph.

How do I detect GHSA-96mh-7xpr-qcgw in my Packagist dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for rainlab/blog-plugin. 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-96mh-7xpr-qcgw 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-96mh-7xpr-qcgw?

O3 pinpoints whether GHSA-96mh-7xpr-qcgw 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-96mh-7xpr-qcgw actively exploited in the wild?

Yes. There are 2 known exploit references for GHSA-96mh-7xpr-qcgw, including 1 documented proof-of-concept exploit on Exploit-DB and 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-96mh-7xpr-qcgw?

GHSA-96mh-7xpr-qcgw has an EPSS (Exploit Prediction Scoring System) score of 2.5%, placing it in the 83th 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-96mh-7xpr-qcgw?

GHSA-96mh-7xpr-qcgw 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-96mh-7xpr-qcgw published, and has it been updated?

GHSA-96mh-7xpr-qcgw was published on May 13, 2022 and was last updated on February 21, 2024. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.
