The WordPress plugin (search engine optimization) vulnerabilities, OR Rank Math has they called it allow remote cyber criminals, according to researchers, to increase their privileges and install malicious redirects on a target Website online.

where the malicious software resides.
Wordfence Said.

The plugin registers an API rest endpoint, the company explained in its collapse, rankmath / v1/UpdateMeta. It calls a function called "update metadata" to remove the trickle on current posts or to delete or change metadata for messages, remarks and phrases. Additionally, this endpoint allows user metadata to be modified.
