CVE-2026-65181: Apache Impala: RCE via External Data Source Class Loading

Noroxi assessment

Priority: Monitor (action score 32/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.54% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Apache Software Foundation Apache Impala 4.5.2.

Low priority for now. Upgrade to Apache Software Foundation Apache Impala 4.5.2 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

Insufficient authorization of Data Source tables in Impala 2.7-4.5 allows a client with privileges to upload a file to remote storage and create a table to execute arbitrary Java code. Users are recommended to upgrade to version 4.5.2, which fixes this issue.
