Executive priority

Treat as a moderate-priority business application issue. It can affect credentials and trust in operational workflows, but the evidence indicates privileges and user interaction are required.

Technical view

CVE-2021-20446 is a network-reachable XSS issue in IBM Maximo for Civil Infrastructure 7.6.2. CVSS 3.0 score is 5.4, with low attack complexity, low privileges required, user interaction required, changed scope, and low confidentiality and integrity impact.

Likely exposure

Exposure is limited to organizations running IBM Maximo for Civil Infrastructure 7.6.2, especially where the Web UI is reachable by ordinary authenticated users.

Exploitation context

The source bundle does not show CISA KEV listing or cited evidence of active exploitation. The main risk is abuse within trusted sessions after user interaction, not unauthenticated remote takeover.
