This high-severity CVE scores 8.3 under NVD CVSS v3. EPSS exploit probability: 2.5%, top 17% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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.
