Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-400: Uncontrolled Resource Consumption, where the product does not properly control the allocation and maintenance of a limited resource. In Sidekiq, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Versions of the package sidekiq before 7.1.3 and 6.5.10 are vulnerable to Denial of Service (DoS) due to insufficient checks in the dashboard-charts.js file. An attacker can exploit this vulnerability by manipulating the localStorage value which will cause excessive polling requests.
