CVE-2026-8166Network attack vector

Stored script execution via undisclosed portal input

Published Aug 6, 2026 · Updated Aug 6, 2026

Stored XSS in Logo Yazılım eLogo Sipariş Portalı before 1.52 allows remote authenticated users to run script in another user's browser. The Turkish national advisory does not identify the affected input field, storage path, or output-rendering locus that fails to neutralize attacker-controlled content. Low-privileged access is required to store the payload, and a different user must view the affected page; resulting script execution can read or alter data available to that user's portal session.
