The open_envvar function in xdg-open in xdg-utils before 1.1.3 does not validate strings before launching the program specified by the BROWSER environment variable, which might allow remote attackers to conduct argument-injection attacks via a crafted URL, as demonstrated by %s in this environment variable.

Affected: Ubuntu:14.04:LTS: xdg-utils, Ubuntu:16.04:LTS: xdg-utils, Ubuntu:18.04:LTS: xdg-utils

It was discovered that xdg-utils incorrectly handled certain inputs. An attacker could possibly use this to execute arbitrary code.
