CVE-2026-45037 Details
Description
Tabby (formerly Terminus) is a highly configurable terminal emulator. Prior to 1.0.232, Tabby's terminal linkifier passes any detected URI directly to the operating system's protocol handler without validating the protocol scheme. This allows a malicious SSH or Telnet server to send crafted terminal output containing dangerous protocol URIs which Tabby renders as clickable links, triggering arbitrary OS protocol handlers on the victim's machine. This vulnerability is fixed in 1.0.232.
A vulnerability in Tabby (formerly Terminus) terminal emulator, prior to version 1.0.232, allows for unsafe execution of protocol handlers. The issue arises because the terminal linkifier directly passes detected URIs to the operating system's protocol handler without validating the protocol scheme. This flaw enables a malicious SSH or Telnet server to send crafted terminal output with dangerous protocol URIs. When clicked, these links trigger arbitrary OS protocol handlers on the user's machine. On unpatched Windows systems, this could lead to remote code execution via known protocol handler exploits.
Users are advised to update to Tabby version 1.0.232 or later. All users should also avoid clicking on application protocol links in SSH or Telnet sessions that they do not understand or trust.
