How severe is CVE-2023-46122?

CVE-2023-46122 has a CVSS score of 3.9/10, rated LOW. Review your exposure and patch according to your risk tolerance.

Which packages are affected by CVE-2023-46122?

CVE-2023-46122 affects the following packages: org.scala-sbt:sbt (Maven), org.scala-sbt:io_2.12 (Maven), org.scala-sbt:io_2.13 (Maven), org.scala-sbt:io_3 (Maven). Ecosystems affected: Maven.

How do I fix CVE-2023-46122?

Update org.scala-sbt:sbt to 1.9.7 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-46122 is resolved across your whole dependency graph.

How do I detect CVE-2023-46122 in my Maven dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.scala-sbt:sbt. 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 CVE-2023-46122 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-2023-46122?

O3 pinpoints whether CVE-2023-46122 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 CVE-2023-46122 actively exploited in the wild?

Yes. There are 1 known exploit references for CVE-2023-46122, including 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-2023-46122?

CVE-2023-46122 has an EPSS (Exploit Prediction Scoring System) score of 0.3%, placing it in the 26th 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-2023-46122?

CVE-2023-46122 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-2023-46122 published, and has it been updated?

CVE-2023-46122 was published on October 23, 2023 and was last updated on April 10, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

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

Description

sbt is a build tool for Scala, Java, and others. Given a specially crafted zip or JAR file, IO.unzip allows writing of arbitrary file. This would have potential to overwrite /root/.ssh/authorized_keys. Within sbt's main code, IO.unzip is used in pullRemoteCache task and Resolvers.remote; however many projects use IO.unzip(...) directly to implement custom tasks. This vulnerability has been patched in version 1.9.7.
