The Rank Math SEO WordPress plugin before 1.0.277 does not verify that the metadata row being updated belongs to the object the user was authorised against, allowing users with the Author role and above to overwrite arbitrary post and user metadata, including that belonging to higher-privileged users.
Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
