Questions about CVE-2026-120775
Is CVE-2026-120775 being exploited?
It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked.Source: cve.now feed data
What does this mean?
The bug is a heap-based buffer overflow in Tanium Deploy, which can let unauthorized code run in the context of Deploy.Source: security.tanium.com
Which versions are affected by CVE-2026-120775?
Deploy: from 2.45.0 before 2.45.322; from 2.40.0 before 2.40.235; from 2.36.0 before 2.36.294.Source: cve.now feed data
Am I affected, and how do I check?
Affected builds are Deploy 2.36.0 to 2.36.294, 2.40.0 to 2.40.235 and 2.45.0 to 2.45.322, covering the 2025H1, 2025H2 and 2026H1 release lines. Compare the installed Deploy version against these ranges. The flaw requires an authenticated Tanium user with the Deploy Software Package write permission.Source: security.tanium.com
How do I fix CVE-2026-120775?
Upgrade Deploy to the fixed build for its release line: 2.36.294, 2.40.235 or 2.45.322.Source: security.tanium.com
