CVE-2026-45037: Tabby open redirect vulnerability

Tabby · Tabby

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.
