AI-suggested

Given the absence of an official patch, European organizations should implement several specific mitigations: 1) Disable or restrict the registration and invocation of the eidos: custom URL handler on endpoints where Eidos is installed, preventing automatic launching of the application via URLs. 2) Employ network-level filtering to block outbound and inbound traffic containing eidos: URL schemes or related payloads, especially in email gateways and web proxies, to reduce exposure to malicious links. 3) Conduct targeted user awareness training focused on phishing risks associated with clicking unknown or suspicious links, emphasizing the dangers of eidos: URLs. 4) Use application whitelisting and endpoint detection and response (EDR) solutions to monitor and block unauthorized execution of the Eidos application or suspicious child processes spawned by it. 5) Isolate systems running Eidos from critical networks where possible, limiting lateral movement if compromise occurs. 6) Monitor logs and network traffic for unusual activity related to the Eidos application or custom URL handler invocations. 7) Engage with the vendor or community for updates and consider temporary removal or disabling of Eidos until a patch is released. These steps go beyond generic advice by focusing on controlling the custom URL handler mechanism and user interaction vectors specific to this vulnerability.

Description

Eidos is an extensible framework for Personal Data Management. Versions 0.21.0 and below contain a one-click remote code execution vulnerability. An attacker can exploit this vulnerability by embedding a specially crafted eidos: URL on any website, including a malicious one they control. When a victim visits such a site or clicks on the link, the browser triggers the app’s custom URL handler (eidos:), causing the Eidos application to launch and process the URL, leading to remote code execution on the victim’s machine. This issue does not have a fix as of October 3, 2025
