## What is CVE-2023-41916?

CVE-2023-41916 is a medium-severity path traversal vulnerability in Apache Linkis DataSource, published on 15 Jul 2024. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

In Apache Linkis =1.4.0, due to the lack of effective filtering
of parameters, an attacker configuring malicious Mysql JDBC parameters in the DataSource Manager Module will trigger arbitrary file reading. Therefore, the parameters in the Mysql JDBC URL should be blacklisted. This attack requires the attacker to obtain an authorized account from Linkis before it can be carried out. Versions of Apache Linkis = 1.4.0 will be affected. 
We recommend users upgrade the version of Linkis to version 1.5.0.

Weakness: CWE-552 (Files or Directories Accessible to External Parties)

Check this codebase for CVE-2023-41916 and fix it if it is affected.

What it is: CVE-2023-41916 is a medium-severity path traversal vulnerability in Apache Linkis DataSource, published on 15 Jul 2024. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2023-41916 in the wild and no public exploit code.

Affected packages and fixed versions:
- org.apache.linkis:linkis-datasource (Maven): affected from 1.4.0; fixed in 1.6.0
- org.apache.linkis:linkis-datasource (Maven): affected from 1.4.0; fixed in 1.6.0

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.
