@simonsmith/cypress-image-snapshothas fix for insecure snapshot file names

Moderate severity GitHub Reviewed Published Jul 31, 2023 in simonsmith/cypress-image-snapshot • Updated Nov 6, 2023

Package

npm @simonsmith/cypress-image-snapshot (npm)

Affected versions

<= 8.0.1

Patched versions

8.0.2

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');

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
