CVE-2026-1694 arcinfo CVE debrief

Who should care

Organizations using PcVue versions 12.0.0 through 16.3.3 should be aware of this vulnerability and take steps to mitigate it, especially if they have not already updated to a patched version. Operators, platform administrators, vulnerability management teams, and security teams should review their deployments and take necessary actions.

Technical summary

The vulnerability exists due to the default configuration of IIS and ASP.net adding HTTP headers that are not removed at the deployment phase of the WebVue, WebScheduler, TouchVue, and SnapVue features in PcVue. This exposes sensitive information about the server configuration. The vulnerability has a CVSS score of 2.3 and is considered low severity. Affected product deployments should be reviewed for exposure, and compensating controls may be necessary.

Defensive priority

Low priority, as the vulnerability has a low CVSS score and is not known to be exploited in the wild.

Recommended defensive actions

• Review and update PcVue to a version that is not vulnerable, if possible.
• Verify that the deployment phase of affected features properly removes unnecessary HTTP headers.
• Monitor for any suspicious activity related to PcVue instances.
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up.
• Review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance.
• Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed.
• Check relevant monitoring, detection, and logs for exposed assets that need extra review.
