CVE-2026-93965 — aiyiyi121 SxDevOps MCP STDIO Server Management services.py subprocess.Popen command injection

A flaw has been found in aiyiyi121 SxDevOps 1.0/1.1. Affected is the function subprocess.Popen of the file backend/aiops/services.py of the component MCP STDIO Server Management. This manipulation of the argument endpoint_or_command causes command injection. The attack may be initiated remotely. Patch name: 2b4bf8585c3e731e7a8af30801ea46680bc783f9. To fix this issue, it is recommended to deploy a patch. The vendor was contacted early, responded in a very professional manner and quickly released a fixed version of the affected product.

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.
How the score was calculated
  • EPSS 1.9% (30-day exploitation probability)+12
  • Technical severity (medium)+3
  • CISA SSVC: exploitation "poc"+5

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

  1. Identify exposed assets running the affected vendor/product/version combinations (Aiyiyi121 SxDevOps).
  2. No fix documented in the sources: reduce exposure and monitor the vendor advisory.
  3. Search available logs for exploit probes matching the vulnerability class (injection), errors and authentication anomalies.
