Base vector

AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N

Name of the Vulnerable Software and Affected Versions: Blog2Social: Social Media Auto Post & Scheduler WordPress plugin versions prior to 6.8.7

Description: The issue is related to a Reflected Cross-Site Scripting problem. It occurs because the b2sShowByDate parameter is not properly sanitised and escaped before being outputted back in an admin page. This allows for malicious scripts to be injected and executed.

Recommendations: For versions prior to 6.8.7, update to version 6.8.7 or later to resolve the issue. As a temporary workaround, consider restricting access to the admin page where the b2sShowByDate parameter is used until the update is applied. Avoid using the b2sShowByDate parameter in the affected admin page until the issue is resolved.
