## What is CVE-2019-10086?

CVE-2019-10086 is a high-severity unsafe deserialization vulnerability in Apache Nifi, published on 20 Aug 2019. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

In Apache Commons Beanutils 1.9.2, a special BeanIntrospector class was added which allows suppressing the ability for an attacker to access the classloader via the class property available on all Java objects. We, however were not using this by default characteristic of the PropertyUtilsBean.

Weakness: CWE-502 (Deserialization of Untrusted Data)

Check this codebase for CVE-2019-10086 and fix it if it is affected.

What it is: CVE-2019-10086 is a high-severity unsafe deserialization vulnerability in Apache Nifi, published on 20 Aug 2019. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2019-10086 in the wild and no public exploit code.

Affected packages and fixed versions:
- commons-beanutils:commons-beanutils (Maven): affected all versions; fixed in 1.9.4
- commons-beanutils:commons-beanutils (Maven): affected all versions; fixed in 1.9.4

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
