PSA: Malware Found in Some Rank Math SEO PRO 3.0.123 Downloads

Rank Math disclosed that some copies of version 3.0.123 of its SEO PRO WordPress plugin contained malware during a specific download window on October 15 and 16, 2026. The affected packages could establish persistent backdoor access, steal credentials, and communicate with an external command server. Rank Math released version 3.0.124 as the clean replacement and provided recovery steps for compromised sites.

Why it matters: WordPress site owners who activated Rank Math SEO PRO 3.0.123 between October 15, 2026 at 20:02 UTC and October 16, 2026 at 07:12 UTC must treat their sites as compromised and perform full recovery, because plugin updates alone will not remove malware that may have established backdoors, unauthorized accounts, or exposed sensitive credentials elsewhere on the server.
