Title
Synk Sweater Comb < 3.8.8 Command Injection via .vervet.yaml Branch Name
Summary
Synk Sweater Comb before 3.8.8 contains a command injection vulnerability that allows an attacker who controls the .vervet.yaml configuration file to execute arbitrary OS commands by injecting malicious input into the linters.<key>.optic-ci.original branch name field. The expectGitBranch() function in src/lint.ts passes the unsanitized branch name directly into child_process.exec() via an unescaped template literal, enabling arbitrary command execution when the lint command is run against the repository.
