Prior to 4.9.4, 5.3.2, and 6.0.0-rc.5, Piscina stores ThreadPool.options in src/index.ts as a plain object that inherits from Object.prototype. Applications with a separate prototype-pollution primitive can therefore supply inherited values for security-sensitive options that do not have own defaults. An inherited execArgv value is passed to the Node.js Worker constructor and can preload attacker-controlled code in worker threads, an inherited loadBalancer function can execute during task scheduling, and inherited env values can alter worker environments. This issue is fixed in versions 4.9.4, 5.3.2, and 6.0.0-rc.5.","state":0,"publishedAt":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":9.2,"severity":null}],"references":["https://github.com/piscinajs/piscina/security/advisories/GHSA-67c8-pqhq-4rmx","https://github.com/piscinajs/piscina/commit/0cb12fca37f526065b072592afe954574dcc656f","https://github.com/piscinajs/piscina/commit/2f69f67159a0e48b38fd61fa4a91c2fdc19fff72","https://github.com/piscinajs/piscina/commit/5be7bbb19e3787bb698862cd516121a578d690f7","https://github.com/piscinajs/piscina/commit/bebbda255c2981cecddd36b171b94be2fd41c9a6","https://github.com/piscinajs/piscina/releases/tag/v4.9.4","https://github.com/piscinajs/piscina/releases/tag/v5.3.2","https://github.com/piscinajs/piscina/releases/tag/v6.0.0-rc.5"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-90364","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Sep 30, 2026, 7:50:18 PM","dateUpdated":"Sep 30, 2026, 8:47:49 PM"},"relatedAdvisories":[{"id":"msrc_CVE-2026-102992","title":"piscina: Prototype-pollution gadget in ThreadPool.options allows RCE via execArgv / loadBalancer / env","vulnerabilityIds":["CVE-2026-102992"]}],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
