Description

Impact

It's possible for a user to pass a relative file path for the snapshot name and reach outside of the project directory into the machine running the test. Example:

  cy.get('h1').matchImageSnapshot('../../../ignore-relative-dirs')

The above will create an ignore-relative-dirs.png three levels up

Patches

Fixed in 8.0.2

Workarounds

Validate all the existing uses of matchImageSnapshot to ensure correct use of the filename argument. Example:

    // snapshot name will be the test title
    cy.matchImageSnapshot();

    // snapshot name will be the name passed in
    cy.matchImageSnapshot('login');
