CVE-2026-4313
CWE-79Published: April 24, 2026· Updated: Apr 27, 2026
Official Description
AdaptiveGRC is vulnerable to Stored XSS via text type fields across the forms. Authenticated attacker can replace the value of the text field in the HTTP POST request. Improper parameter validation by the server results in arbitrary JavaScript execution in the victim's browser.
Critically, this may allow the attacker to obtain the administrator authentication token and perform arbitrary actions with administrative privileges, which could lead to further compromise.
This issue occurs in versions released before December 2025.
Technical Analysis
CVE-2026-4313 requires adjacent network access, limiting remote exploitation but still posing risk in shared or local network environments.
Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
From a weakness classification perspective (CWE-79): Cross-site scripting (XSS) vulnerabilities allow attackers to inject malicious scripts into web pages viewed by other users.
