CyberRota Analysis
AI-GeneratedThe vulnerability affects the GitHub Actions workflow, specifically the `discord-issue.yml`, which improperly handles user-supplied issue titles, allowing for shell command execution on the GitHub Actions runner. This can lead to the manipulation or spoofing of trusted bot notifications and potentially expose sensitive data, such as Discord webhook secrets, depending on repository permissions. Organizations utilizing GitHub Actions, especially those integrating with Discord, should prioritize addressing this issue to mitigate risks associated with unauthorized command execution and data exposure.

Original NVD Description
githubtoplanguages generates a user's top GitHub languages as an SVG. The .github/workflows/discord-issue.yml workflow runs when an issue is opened or closed and interpolates github.event.issue.title directly into the Bash assignment for ISSUE_TITLE before shell parsing. An issue title containing shell command-substitution syntax can therefore execute commands on the GitHub Actions runner before the title is included in the Discord notification sent through DISCORD_WEBHOOK. Successful exploitation can manipulate or spoof trusted bot notifications and may expose the Discord webhook secret or other workflow environment data, depending on repository permissions. This issue is fixed by commit 6bf9c3a9cb66c937b9047ca266b3d02f2bb11027.
