Refer to Qlik Sense vendor guidance for patches and updates to address this path traversal vulnerability. Ensure proper access controls are in place to restrict unauthorized access.
Technical Analysis
CVE-2023-41266 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
CISA has added CVE-2023-41266 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
