Shamefile is a linter for undocumented linter warnings. Prior to version 0.1.7, a path traversal vulnerability in "shame next" allows an attacker-controlled "shamefile.yaml" to disclose contents of files outside the repository, one line at a time, to the terminal of a user who runs the command. See patch commit for technical details. The issue is fixed in 0.1.7. Upgrade to either 0.1.7 or later versions to incorporate the patch. As a workaround, do not run "shame next" against untrusted "shamefile.yaml". Use "shame me --dry-run" for CI validation.
