Description

Improper Input Validation vulnerability in Apache Hop Engine. This issue affects Apache Hop Engine: before 2.8.0.

Users are recommended to upgrade to version 2.8.0, which fixes the issue.

When Hop Server writes links to the PrepareExecutionPipelineServlet page one of the parameters provided to the user was not properly escaped. The variable not properly escaped is the "id", which is not directly accessible by users creating pipelines making the risk of exploiting this low.

This issue only affects users using the Hop Server component and does not directly affect the client.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.apache.hop:hop, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update org.apache.hop:hop to 2.8.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-24683 is resolved across your whole dependency graph.

  3. Workarounds

    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.
