DescriptionCVE.org
Missing Authorization vulnerability in OpenText™ Filr allows Authentication Bypass. The vulnerability could allow unauthenticated users to get XSRF token and do RPC with carefully crafted programs.
This issue affects Filr: through 25.1.2.
Executive ViewAI
CVE-2026-3266 is a critical authentication bypass vulnerability in OpenText Filr that allows unauthenticated attackers to obtain security tokens and execute unauthorized Remote Procedure Calls (RPC). This vulnerability poses an immediate risk to any organization using Filr, as attackers can gain unauthorized access without valid credentials, potentially leading to data theft, system compromise, or lateral movement within the network.
Implement Web Application Firewall (WAF) rules to block unauthorized RPC requests and XSRF token generation endpoints; restrict network access to Filr through IP whitelisting and VPN-only policies; disable RPC functionality if business operations permit; enable enhanced logging and monitoring for authentication attempts; consider air-gapping critical Filr instances until patch availability; implement network segmentation to limit lateral movement if compromise occurs.
