Security readout for executives and security teams
Plain-English summary
CVE-2026-1446 is a local cross-site scripting issue in Esri ArcGIS Pro 3.6.0 and earlier. A standard local user could provide malicious text that runs when another user opens a specific ArcGIS Pro dialog. This is not described as remotely exploitable. Esri says it is fixed in ArcGIS Pro 3.6.1.
Executive priority
Treat as a routine but time-bound workstation patch. It is not presented as internet-exploitable or actively exploited, but it can affect GIS users handling untrusted local content. Upgrade to ArcGIS Pro 3.6.1 during the next managed patch cycle, sooner for shared environments.
Technical view
The issue is CWE-79 XSS with CVSS 3.1 score 5.0: AV:L/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N. Exploitation requires local access and user interaction with a specific dialog. Potential impact is limited confidentiality and integrity loss, with no availability impact stated. Scope is changed because script execution may affect a different security context within the application.
Likely exposure
Organizations running Esri ArcGIS Pro 3.6.0 or earlier on user workstations are potentially exposed. Risk is most relevant where untrusted local users can influence ArcGIS Pro content or shared project data later opened by another user.
Exploitation context
No active exploitation is stated in the provided sources, and the CVE is not marked KEV. Exploitation requires local interaction with ArcGIS Pro and user action to open the affected dialog. This lowers internet-scale urgency but still matters on shared workstations or multi-user GIS environments.
Researcher notes
The public record provides limited technical detail and does not identify the specific dialog. Avoid assuming broader attack surface beyond local user interaction in ArcGIS Pro. The affected-product metadata appears sparse, so validation should rely on the narrative version range and Esri patch advisory.
Mitigation direction
- Upgrade ArcGIS Pro to version 3.6.1, which Esri identifies as the fixed version.
- Prioritize systems used in shared, lab, contractor, or multi-user GIS workflows.
- Limit trust in locally supplied ArcGIS Pro content until patched.
- Review Esri’s patch notice for deployment prerequisites and operational guidance.
Validation and detection
- Inventory ArcGIS Pro installations and identify versions 3.6.0 and earlier.
- Confirm patched endpoints report ArcGIS Pro version 3.6.1 or later.
- Check software deployment tools for failed or deferred ArcGIS Pro patch installations.
- Document any endpoints that cannot be upgraded and track vendor guidance.
