Which packages are affected by GHSA-8r28-r8cp-g6cp?

GHSA-8r28-r8cp-g6cp affects the following packages: org.apache.hadoop:hadoop-common (Maven), org.apache.hadoop:hadoop-common (Maven). Ecosystems affected: Maven.

How do I fix GHSA-8r28-r8cp-g6cp?

Update org.apache.hadoop:hadoop-common to 2.6.4 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-8r28-r8cp-g6cp is resolved across your whole dependency graph.

How do I detect GHSA-8r28-r8cp-g6cp in my Maven dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.apache.hadoop:hadoop-common. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

How do I mitigate GHSA-8r28-r8cp-g6cp if there is no patch (or I can't update yet)?

If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

How does O3 Security protect against GHSA-8r28-r8cp-g6cp?

O3 pinpoints whether GHSA-8r28-r8cp-g6cp is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is GHSA-8r28-r8cp-g6cp actively exploited in the wild?

No public exploit code has been indexed for GHSA-8r28-r8cp-g6cp yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

Description

This is an information disclosure vulnerability in Apache Hadoop before 2.6.4 and 2.7.x before 2.7.2 in the short-circuit reads feature of HDFS. A local user on an HDFS DataNode may be able to craft a block token that grants unauthorized read access to random files by guessing certain fields in the token.
