Vulnerability Title
dbt has a Command Injection in Reusable Workflow via Unsanitized comment-body Output
Source: CVE Program / CVE List V5
Vulnerability Description
dbt enables data analysts and engineers to transform their data using the same practices that software engineers use to build applications. Inside the reusable workflow dbt-labs/actions/blob/main/.github/workflows/open-issue-in-repo.yml, the prep job uses peter-evans/find-comment to search for an existing comment indicating that a docs issue has already been opened. The output steps.issue_comment.outputs.comment-body is then interpolated directly into a bash if statement. Because comment-body is attacker-controlled text and is inserted into shell syntax without escaping, a malicious comment body can break out of the quoted string and inject arbitrary shell commands. This vulnerability is fixed with commit bbed8d28354e9c644c5a7df13946a3a0451f9ab9.
