## What is CVE-2023-29215?

CVE-2023-29215 is a critical unsafe deserialization vulnerability in Apache Linkis, published on 10 Apr 2023. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

In Apache Linkis <=1.3.1, due to the lack of effective filtering
of parameters, an attacker configuring malicious Mysql JDBC parameters in JDBC EengineConn Module will trigger a
deserialization vulnerability and eventually lead to remote code execution. Therefore, the parameters in the Mysql JDBC URL should be blacklisted. Versions of Apache Linkis <= 1.3.0 will be affected.
We recommend users upgrade the version of Linkis to version 1.3.2.

Weakness: CWE-502 (Deserialization of Untrusted Data)

Check this codebase for CVE-2023-29215 and fix it if it is affected.

What it is: CVE-2023-29215 is a critical unsafe deserialization vulnerability in Apache Linkis, published on 10 Apr 2023. 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-2023-29215 in the wild and no public exploit code.

Affected packages and fixed versions:
- org.apache.linkis:linkis-engineconn (Maven): affected all versions; fixed in 1.3.2
- org.apache.linkis:linkis-engineconn (Maven): affected all versions; fixed in 1.3.2

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.
