3. Impact: The successful exploitation of this vulnerability could allow attackers to execute arbitrary scripts on affected websites, leading to various malicious activities such as stealing sensitive information, redirecting users to phishing sites, or installing malware.

Mitigation Strategies:

1. Update WordPress and Plugin: The most effective mitigation strategy is to update WordPress and the Meks Smart Social Widget plugin to the latest versions, which address this vulnerability.

2. Restrict Administrative Access: Implement strict access control measures to limit the number of users with administrator-level privileges. Use strong passwords and enforce regular password changes.
