Which packages are affected by CVE-2009-4665?

CVE-2009-4665 affects the following packages: CuteEditor (NuGet). Ecosystems affected: NuGet.

How do I fix CVE-2009-4665?

Update CuteEditor to 6.6 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2009-4665 is resolved across your whole dependency graph.

How do I detect CVE-2009-4665 in my NuGet dependencies?

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

How do I mitigate CVE-2009-4665 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 CVE-2009-4665?

O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2009-4665 can be triaged on real exposure rather than presence alone.

Is CVE-2009-4665 actively exploited in the wild?

Yes. There are 2 known exploit references for CVE-2009-4665, 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 CVE-2009-4665?

CVE-2009-4665 has an EPSS (Exploit Prediction Scoring System) score of 6.5%, placing it in the 94th 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 CVE-2009-4665?

CVE-2009-4665 is classified as Path Traversal (CWE-22). 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 CVE-2009-4665 published, and has it been updated?
