File write via unsanitized snapshot name
Published Aug 4, 2023 · Updated Oct 4, 2024
Path traversal in Cypress Image Snapshot 8.0.1 and earlier allows remote authenticated users to write images outside the project directory. runImageDiffAfterScreenshot used screenshotConfig.name as the snapshot filename without removing relative path segments, so jest-image-snapshot resolved attacker-controlled directories. The input must reach matchImageSnapshot during a Cypress run; the resulting write uses the test runner's filesystem permissions, with no published evidence of command execution.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
