Microsoft Azure CycleCloud: OS command injection allows privilege escalation
Summary
Microsoft has published CVE-2026-102224 for Azure CycleCloud, rated High (CVSS 3.1 8.4). An OS command injection (CWE-78) allows an authorized attacker to elevate privileges over the network. The attacker needs high privileges on the CycleCloud system and user interaction, so this is not an unauthenticated attack. No exploitation has been observed so far.
Affected
- Microsoft Azure CycleCloud from 1.0.0 before 8.10.1 (per CNA record)
Fixed in
- Azure CycleCloud 8.10.1 (per CNA record and VulDB; confirm on the MSRC advisory)
- Unknown whether older maintained branches received separate fixes
Workaround
Unknown. No vendor workaround was found. Upgrading to 8.10.1 is the documented remedy.
Exploitation
- No evidence of exploitation in the wild.
- Not listed in CISA's Known Exploited Vulnerabilities catalogue.
- No public proof of concept found.
- CISA SSVC: exploitation none, not automatable, total technical impact.
- Rapid7 rates exploitation as less likely.
Our recommendation
- Inventory all Azure CycleCloud instances and their versions.
- Upgrade to 8.10.1 or later after confirming the fixed version on the MSRC advisory.
- Limit and audit administrative accounts, since high privileges are required.
- Check whether the CycleCloud web interface or API is reachable from the internet and restrict it if so.
- Monitor the MSRC advisory and NVD, as NVD analysis was still pending.
