## What is CVE-2022-36364?

CVE-2022-36364 is a high-severity code injection vulnerability in Apache Calcite Avatica, published on 28 Jul 2022. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

Apache Calcite Avatica JDBC driver creates HTTP client instances based on class names provided via `httpclient_impl` connection property; however, the driver does not verify if the class implements the expected interface before instantiating it, which can lead to code execution loaded via arbitrary classes and in rare cases remote code execution. To exploit the vulnerability: 1) the attacker needs to have privileges to control JDBC connection parameters; 2) and there should be a vulnerable class (constructor with URL parameter and ability to execute code) in the classpath. From Apache Calcite Avatica 1.22.0 onwards, it will be verified that the class implements the expected interface before invoking its constructor.

Weakness: CWE-665 (Improper Initialization)

Check this codebase for CVE-2022-36364 and fix it if it is affected.

What it is: CVE-2022-36364 is a high-severity code injection vulnerability in Apache Calcite Avatica, published on 28 Jul 2022. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2022-36364 in the wild and no public exploit code.

Affected packages and fixed versions:
- org.apache.calcite.avatica:avatica-core (Maven): affected all versions; fixed in 1.22.0
- org.apache.calcite.avatica:avatica-core (Maven): affected all versions; fixed in 1.22.0

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.
