Unprotected dynamically loaded chunks

Low severity GitHub Reviewed Published Oct 18, 2020 in waysact/webpack-subresource-integrity • Updated Feb 1, 2023

Package

npm webpack-subresource-integrity (npm)

Affected versions

< 1.5.1

Patched versions

1.5.1

Description

Impact

All dynamically loaded chunks receive an invalid integrity hash that is ignored by the browser, and therefore the browser cannot validate their integrity. This removes the additional level of protection offered by SRI for such chunks. Top-level chunks are unaffected.

Patches

This issue is patched in version 1.5.1.

Workarounds

N/A

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.
