Detailsinfo

A vulnerability was found in gouef githubtoplanguages (version unknown) and classified as critical. This issue affects an unknown function of the file .github/workflows/discord-issue.yml. The manipulation of the argument issue.title with an unknown input leads to a os command injection vulnerability. Using CWE to declare the problem leads to CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

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.
