Zoom Patches Critical Windows Flaw That Could Let Attackers Escalate Privileges
  • Zoom recommends installing the latest available update; users can check their version under Help > About Zoom Workplace and update through Check for Updates or Zoom’s official download center.

  • Zoom disclosed two vulnerabilities in Zoom Workplace for Windows that could allow unauthenticated attackers with network access to escalate privileges, though both require user interaction.

  • The more severe flaw, CVE-2026-108186, is an input-validation bug rated critical at CVSS 9.6, affecting versions 7.1.0 through releases earlier than 7.1.8.

  • The second flaw, CVE-2026-108187, stems from an incorrect origin check, is rated high at CVSS 8.1, and affects releases earlier than 7.1.5.

  • Zoom’s Offensive Security team found the critical flaw, while researcher shmoul reported the second; Zoom said neither has been confirmed exploited in the wild.

  • Zoom’s advisories provide limited technical detail, including no explanation of what user action could trigger an attack or a complete exploitation chain.

  • Zoom Workplace for Windows 7.1.8 fixes CVE-2026-108186 and version 7.1.5 fixes CVE-2026-108187; the current 7.2.5 release includes fixes for both.

  • Organizations should find vulnerable installations across managed Windows devices, deploy and verify updates through approved tools, and monitor for suspicious privilege changes or application behavior.

  • The severity scores describe potential impact, not confirmed compromise, but delayed updates to widely used workplace software can leave organizations exposed.

  • The disclosures follow other Zoom security issues cited in the article, including the August 2026 “Zoomsday” zero-click memory-corruption flaw, CVE-2026-53413, and a critical Windows account-takeover vulnerability fixed in July, CVE-2026-53412.
