QID 997732: Rubygems (Rubygems) Security Update for discordrb (GHSA-8832-4mm5-x2r6)

discordrb is an implementation of the Discord API using Ruby. In discordrb before commit 91e13043ffa the encoder.rb file unsafely constructs a shell string using the file parameter, which can potentially leave clients of discordrb vulnerable to command injection. The library is not directly exploitable: the exploit requires that some client of the library calls the vulnerable method with user input. However, if unsafe input reaches the library method, then an attacker can execute arbitrary shell commands on the host machine. Full impact will depend on the permissions of the process running the discordrb library and will likely not be total system access. This issue has been addressed in code, but a new release of the discordrb gem has not been uploaded to rubygems. This issue is also tracked as GHSL-2022-094.

Successful exploitation of this vulnerability could lead to a security breach or could affect integrity, availability, and confidentiality.

CVSS V3 rated as Critical - 9.6 severity.

CVSS V2 rated as High - 7.5 severity.
