CVE-2025-59715

Administrator-session script execution via unsanitized contact fields

Published Sep 19, 2025 · Updated Sep 19, 2025

Stored cross-site scripting in SMSEagle before 6.11 allows local users with high privileges to execute JavaScript through contact fields. Certain web-GUI controls store username and contact phone-number input without sanitizing it before rendering the values. The payload runs in an administrator's browser when the administrator edits the affected property, requiring a high-privilege input path and a separate administrator action.
