A tampered build of Ninja Tables Pro 5.2.11 was distributed through a decommissioned update server, embedding a malicious PHP updater component that grants attackers persistent backdoor access. The compromised plugin creates a passwordless admin account, drops web shells in mu-plugins and uploads directories, and registers scheduled tasks that survive plugin removal, making remediation difficult. Organizations running affected WordPress instances face full site takeover risk, including any hosted applications, APIs, or backend services running on the same host.
