Browser script execution via summary_state reflection
Published Feb 4, 2025 · Updated Nov 3, 2025
Reflected XSS in NagVis 1.9.40 allows remote attackers to execute JavaScript through a crafted cross-origin POST request. The std_table.php gadget parses members as JSON and writes its summary_state property into a script tag without validation or output encoding. Exploitation requires a victim to load an attacker-controlled page that submits the POST; the script then acts in the NagVis origin as that user.
