{"apiVersion":"1.0","identifier":"CVE-2026-53970","description":"ZeroBrew version 0.3.1 and prior contains a missing integrity verification vulnerability in the Ruby compatibility shim that allows network attackers to execute arbitrary code by substituting malicious content at formula resource or URL-based patch URLs without checksum validation. Attackers can intercept or replace downloads for secondary resource and patch paths in shim.rb, injecting attacker-controlled build steps or source tree modifications that execute during source builds via -zb install --build-from-source- without any integrity warning.","publishedAt":"2026-08-14T16:16:57","lastModifiedAt":"2026-08-18T02:17:27","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-53970","cvssScore":7.5,"cvssVector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H","epssProbability":0.0017,"riskScore":0.76,"affectedProduct":"ZeroBrew","affectedVersions":"<=0.3.1","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-53970","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-53970","en":"https://www.redsauce.net/en/cves/CVE-2026-53970","fr":"https://www.redsauce.net/fr/cves/CVE-2026-53970","pt":"https://www.redsauce.net/pt/cves/CVE-2026-53970","de":"https://www.redsauce.net/de/cves/CVE-2026-53970","sk":"https://www.redsauce.net/sk/cves/CVE-2026-53970","el":"https://www.redsauce.net/el/cves/CVE-2026-53970"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-53970"}}
