Last modified

CVE-2026-75486 is a high-severity vulnerability rated 8/10 on the CVSS scale. 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.. EPSS estimates a 1.25% chance of exploitation in the next 30 days.
