Administrator-planted script execution in visitors' browsers
Published Jun 6, 2025 · Updated Apr 28, 2026
Stored XSS in PowieT Powie's Uptime Robot 0.9.7 and earlier allows remote authenticated users to inject scripts into site pages. Public advisories do not identify the affected field or function, stating only that insufficiently neutralized input is stored and later emitted during page generation. Administrator privileges are required to plant the payload, and exploitation requires another user to visit the affected content; the script then runs in that visitor's browser.
