Liquid Web issued a security advisory warning WordPress customers of two critical vulnerabilities: an unauthenticated remote code execution flaw in Avada Builder (versions 3.15.2 and earlier) and an authentication bypass in UpdraftPlus (versions 1.26.4 and earlier), both capable of allowing attackers to take control of affected sites. The advisory remained active for approximately 13 days while customers were urged to update the affected plugins and audit their WordPress installations for signs of compromise. The incident was resolved on July 9, 2026, with Liquid Web continuing to recommend plugin updates and adherence to WordPress security best practices.
