## What is CVE-2025-46762?

CVE-2025-46762 is a high-severity unsafe deserialization vulnerability in Apache Parquet Java, published on 6 May 2025. An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.

### Official description

Schema parsing in the parquet-avro module of Apache Parquet 1.15.0 and previous versions allows bad actors to execute arbitrary code.

While 1.15.1 introduced a fix to restrict untrusted packages, the default setting of trusted packages still allows malicious classes from these packages to be executed.

The exploit is only applicable if the client code of parquet-avro uses the "specific" or the "reflect" models deliberately for reading Parquet files. ("generic" model is not impacted)

Users are recommended to upgrade to 1.15.2 or set the system property "org.apache.parquet.avro.SERIALIZABLE_PACKAGES" to an empty string on 1.15.1. Both are sufficient to fix the issue.

Weakness: CWE-73 (External Control of File Name or Path)

Check this codebase for CVE-2025-46762 and fix it if it is affected.

What it is: CVE-2025-46762 is a high-severity unsafe deserialization vulnerability in Apache Parquet Java, published on 6 May 2025. An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of CVE-2025-46762 in the wild and no public exploit code.

Affected packages and fixed versions:
- org.apache.parquet:parquet-avro (Maven): affected all versions; fixed in 1.15.2
- org.apache.parquet:parquet-avro (Maven): affected all versions; fixed in 1.15.2

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.
