Sidekiq is reflected XSS vulnerability. The value of substr parameter is reflected in the response without any encoding, allowing an attacker to inject Javascript code into the response of the application.  An attacker could exploit it to target users of the Sidekiq Web UI. Moreover, if other applications are deployed on the same domain or website as Sidekiq, users of those applications could also be affected, leading to a broader scope of compromise. Potentially compromising their accounts, forcing the users to perform sensitive actions, stealing sensitive data, performing CORS attacks, defacement of the web application, etc. This issue has been patched in version 7.2.4.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:L/I:L/A:L","score":5.5},"cwes":["CWE-79"],"references":["https://github.com/sidekiq/sidekiq/commit/30786e082c70349ab27ffa9eccc42fb0c696164d","https://github.com/sidekiq/sidekiq/releases/tag/v7.2.4","https://github.com/sidekiq/sidekiq/security/advisories/GHSA-q655-3pj8-9fxq","https://github.com/sidekiq/sidekiq/commit/30786e082c70349ab27ffa9eccc42fb0c696164d","https://github.com/sidekiq/sidekiq/releases/tag/v7.2.4"],"products":[],"source":"nvd","synced_at":"2026-10-19T21:49:08.435428910+00:00"},"epss":{"cve":"CVE-2024-32887","score":0.00594,"percentile":0.48412,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-q655-3pj8-9fxq","url":"https://osv.dev/vulnerability/GHSA-q655-3pj8-9fxq","summary":"Sidekiq vulnerable to a Reflected XSS in Queues Web Page","modified":"2026-06-08T23:30:18.654877875Z","packages":[{"ecosystem":"RubyGems","name":"sidekiq","purl":"pkg:gem/sidekiq","ranges":[">=7.2.0 <7.2.4"],"fixed":["7.2.4"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
