Which packages are affected by GHSA-395x-wv32-44v5?

GHSA-395x-wv32-44v5 affects the following packages: baserproject/basercms (Packagist). Ecosystems affected: Packagist.

How do I fix GHSA-395x-wv32-44v5?

Update baserproject/basercms to 4.7.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-395x-wv32-44v5 is resolved across your whole dependency graph.

How do I detect GHSA-395x-wv32-44v5 in my Packagist dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for baserproject/basercms. 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-395x-wv32-44v5 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-395x-wv32-44v5?

O3 pinpoints whether GHSA-395x-wv32-44v5 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-395x-wv32-44v5 actively exploited in the wild?

No public exploit code has been indexed for GHSA-395x-wv32-44v5 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-395x-wv32-44v5?

GHSA-395x-wv32-44v5 has an EPSS (Exploit Prediction Scoring System) score of 0.5%, placing it in the 42th 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-395x-wv32-44v5?

GHSA-395x-wv32-44v5 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-395x-wv32-44v5 published, and has it been updated?

GHSA-395x-wv32-44v5 was published on November 28, 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.
