XLab reports that attackers exploited Ghost CMS CVE-2026-26980 to steal admin API keys and inject ClickFix scripts on more than 700 sites. Ghost fixed the flaw in version 6.19.1; administrators should upgrade and rotate keys.

Key points

  • XLab reported that the campaign affected more than 700 domains, including sites linked to Harvard University, Oxford University, Auburn University, and DuckDuckGo.
  • CVE-2026-26980 affects Ghost 3.24.0 through 6.19.0 and allows unauthenticated attackers to read database data, including admin API keys.
  • Attackers used stolen keys to inject JavaScript into articles; the scripts fetched cloaking code that selected visitors for a fake Cloudflare ClickFix prompt.
  • The prompt instructed victims to paste a command into Windows Command Prompt, leading to payloads including DLL loaders, JavaScript droppers, and UtilifySetup.exe.
  • Researchers observed two activity clusters, including cases where attackers re-infected sites or replaced another cluster’s scripts.
  • Ghost released a fix in version 6.19.1 on February 19. Administrators are advised to upgrade, rotate previously used keys, inspect and remove injected scripts, and retain 30 days of admin API logs.
