CVE-2026-49326: Apache HBase: Missing scanner instance owner check in thrift delegation service

Noroxi assessment

Priority: Monitor (action score 26/100)

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: 0.49% (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 HBase 3.0.0-beta-2.
Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Apache Software Foundation Apache HBase 3.0.0-beta-2 or later.

Missing Authorization vulnerability in Apache HBase thrift and rest delegation service. A scan operation in thrift/rest service has 3 steps, open, fetch(possible multiple times), close. The open step will return an id which will be passed back to server for identifying the scanner instances stored at server side. We missed the owner check in fetch and close steps which means a user can fetch rows from the scanner which is opened by other users, and close scanners which belongs to other users. This issue affects Apache HBase:from 3.0.0-alpha-1 through 3.0.0-beta-1, from 2.6.0 through 2.6.5, from 2.5.0 through 2.5.14, through 2.4.*. Users are recommended to upgrade to version 3.0.0-beta-2, 2.6.6 and 2.5.15, which fixes the issue.
