Terminology before 1.3.1 allows Remote Code Execution because popmedia is
mishandled, as demonstrated by an unsafe “cat README.md” command when \e}pn
is used. A popmedia control sequence can allow the malicious execution of
executable file formats registered in the X desktop share MIME types
(/usr/share/applications). The control sequence defers unknown file types
to the handle_unknown_media() function, which executes xdg-open against the
filename specified in the sequence. The use of xdg-open for all unknown
file types allows executable file formats with a registered shared MIME
type to be executed. An attacker can achieve remote code execution by
introducing an executable file and a plain text file containing the control
sequence through a fake software project (e.g., in Git or a tarball). When
the control sequence is rendered (such as with cat), the executable file
will be run.
