xdg-utils < 1.1.3 - Argument Injection via BROWSER Environment Variable

Title source: llm
STIX 2.1

Description

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.
