Summary
The Blog2Social plugin for WordPress is vulnerable to Server-Side Request Forgery up to version 8.6.0 via the getFullContent() function.

Recommendation
It is recommended to update the Blog2Social plugin to the latest patched version. Also, restrict access to the getFullContent() function and apply URL filtering.
Other vulnerabilities in Blog2Social
See all- CVE-2026-89030Medium
The Blog2Social plugin for WordPress before version 9.1.0 exposes the email addresses of all registered users to low-privileged accounts. The b2s_search_user AJAX handler in includes/Ajax/Get.php calls B2S_Tools::searchUser() in includes/Tools.php, which returns the email address of every matching user without restricting access to callers holding the list_users capability, allowing any user with the edit_posts capability to retrieve user email addresses including those of administrators.
- CVE-2026-89029Medium
The Blog2Social plugin for WordPress before version 9.1.0 allows low-privileged users to enumerate WordPress user accounts. The b2s_get_select_mandant_user AJAX handler in includes/Ajax/Get.php resolves arbitrary user IDs supplied in the owner parameter to display names without verifying that the caller is authorized to read user account data, allowing any user with the edit_posts capability to map WordPress user IDs to display names and confirm account existence for arbitrary IDs.
- CVE-2026-56044High
The vulnerability allows an unauthenticated attacker to perform XSS attacks in Blog2Social version 8.9.2 and earlier. The attack can be carried out without authentication, increasing the risk of exploitation.
