Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for magento/community-edition. 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-8mq8-c243-2335 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-8mq8-c243-2335?

O3 pinpoints whether GHSA-8mq8-c243-2335 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-8mq8-c243-2335 actively exploited in the wild?

No public exploit code has been indexed for GHSA-8mq8-c243-2335 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-8mq8-c243-2335?

GHSA-8mq8-c243-2335 has an EPSS (Exploit Prediction Scoring System) score of 0.6%, placing it in the 44th 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.

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.

Description

Adobe Commerce versions 2.4.9-alpha1, 2.4.8-p1, 2.4.7-p6, 2.4.6-p11, 2.4.5-p13, 2.4.4-p14 and earlier are affected by a stored Cross-Site Scripting (XSS) vulnerability that could be exploited by a low-privileged attacker to inject malicious scripts into vulnerable form fields. These scripts may be used to escalate privileges within the application or compromise sensitive user data. Exploitation of this issue requires user interaction in that a victim must browse to the page containing the vulnerable field. Scope is changed.
