CVE-2026-36226 is a cross-site scripting (XSS) vulnerability in Advantech WebAccess/SCADA 8.0-2015.08.16. According to the provided content, the issue is reachable via the decryption field in the Create New Project User component. An attacker can supply crafted script content to that field and, if the application fails to properly neutralize it before rendering in a victim’s browser, arbitrary client-side script may execute in the security context of the WebAccess/SCADA application. The provided information does not specify whether the XSS is stored or reflected, nor does it identify the exact vulnerable function or code path.

This repository is a small, manual proof-of-concept for CVE-2026-36226, an XSS vulnerability in Advantech WebAccess/SCADA 8.0-2015.08.16. The repo contains mostly documentation (README.md, PUBLIC-POC.md, ATTACK-SCENARIO.md), a payload list (payloads.txt), and a single helper page (poc.html). The exploit capability is limited to browser-side XSS verification: it supplies benign payloads intended to be pasted into the vulnerable 'decryption' field of the Admin Dashboard's 'Create New Project User' component. When the application later renders that field without proper output encoding, the payload executes as JavaScript in the victim user's browser context. The included poc.html does not attack the target directly and does not send network traffic; it only displays a default payload and copies it to the clipboard using navigator.clipboard.writeText(). There are no hardcoded remote target URLs, no automation against the product, and no malicious post-exploitation logic such as cookie theft or exfiltration. Overall, this is a legitimate but low-maturity public PoC focused on manual reproduction of a web/browser XSS issue rather than a weaponized exploit.
