Detailsinfo

A vulnerability, which was classified as problematic, was found in MailerSend Plugin up to 1.0.7. Affected is some unknown functionality of the component Configuration Delete.

This is going to have an impact on integrity. CVE summarizes:

The MailerSend WordPress plugin before 1.0.8 does not perform a nonce check on its configuration-delete action (it verifies the manage_options capability but ignores the nonce), so an attacker can trick a logged-in administrator into visiting a crafted page that wipes the MailerSend WordPress plugin before 1.0.8's SMTP configuration and deactivates the MailerSend WordPress plugin before 1.0.8, breaking the site's email delivery.
