CVE-2026-7051: Missing Authorization in Blog2Social

The impact of this vulnerability is significant, as it allows an attacker with legitimate WordPress user credentials to maliciously delete the posts of other users. This could lead to data loss, denial of service for affected users, and reputational damage for the website owner. An attacker could systematically target high-profile users or critical content, causing widespread disruption. While requiring authentication, the ease of exploitation makes it a concerning risk, particularly on multi-user WordPress installations where user permissions may not be strictly enforced. The potential for abuse is amplified if the attacker gains access to an administrator account.

The primary mitigation is to upgrade Blog2Social to version 8.9.1 or later, which contains the necessary fix. If immediate upgrading is not possible, consider implementing stricter user permission controls within WordPress to limit the privileges of authenticated users. Review the plugin's configuration to ensure that user roles are appropriately defined and that access to sensitive functions is restricted. Implement a Web Application Firewall (WAF) rule to block requests containing suspicious 'postId' parameters. Monitor WordPress logs for unusual deletion activity, specifically looking for patterns of sequential 'postId' values being targeted. After upgrading, confirm the fix by attempting to delete a post as a user with limited privileges; the action should be denied.
