Command injection via crafted filenames in Super-linter Action_CVE-2026-25761

8.8 / 10

HIGH

CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H

Description

Super-linter is a combination of multiple linters to run as a GitHub Action or standalone. From 6.0.0 to 8.3.0, the Super-linter GitHub Action is vulnerable to command injection via crafted filenames. When this action is used in downstream GitHub Actions workflows, an attacker can submit a pull request that introduces a file whose name contains shell command substitution syntax, such as $(...). In affected Super-linter versions, runtime scripts may execute the embedded command during file discovery processing, enabling arbitrary command execution in the workflow runner context. This can be used to disclose the job’s GITHUB_TOKEN depending on how the workflow configures permissions. This vulnerability is fixed in 8.3.1.
