Description

Notable before 1.9.0-beta.8 doesn't effectively prevent the opening of executable files when clicking on a link. There is improper validation of the file URI scheme. A hyperlink to an SMB share could lead to execution of an arbitrary program (or theft of NTLM credentials via an SMB relay attack, because the application resolves UNC paths).

Notable: before 1.9.0; 1.9.0-beta0, 1.9.0-beta1, 1.9.0-beta2, 1.9.0-beta3, 1.9.0-beta4, 1.9.0-beta5 (+2) — fixed in 1.9.0

How to fix

Upgrade to a fixed version: Notable 1.9.0. Check the vendor advisory for mitigations.
