Affected by this vulnerability is an unknown functionality of the file dbt-labs/actions/blob/main/.github/workflows/open-issue-in-repo.yml of the component Comment Handler. The manipulation of the argument steps.issue_comment.outputs.comment- results in os command injection. This vulnerability was named CVE-2026-39382. The attack may be performed from remote. There is no available exploit. A patch should be applied to remediate this issue. Detailsinfo A vulnerability was found in dbt-labs dbt-core (affected version not known). It has been classified as critical. Affected is some unknown functionality of the file dbt-labs/actions/blob/main/.github/workflows/open-issue-in-repo.yml of the component Comment Handler. The manipulation of the argument steps.issue_comment.outputs.comment- with an unknown input leads to a os command injection vulnerability. CWE is classifying the issue as 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. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes: 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.
