CVE-2026-27415

Vulnerability

Overview

The BEAR plugin for WordPress, versions from n/a through 1.1.5, contains a Cross-Site Request Forgery (CSRF) vulnerability [1]. This flaw stems from insufficient validation of request origins, enabling an attacker to trick an authenticated administrator into performing unintended actions on their behalf.

Exploitation

Method

Exploitation requires user interaction: a privileged user must click a malicious link, visit a crafted page, or submit a specially prepared form while logged into the WordPress admin panel [1]. No direct authentication is needed for the attacker, but the victim must have sufficient privileges for the forged action to succeed.

ImpactSuccessful exploitation allows an attacker to force higher-privileged users to execute unwanted actions under their current authentication session [1]. This could include modifying plugin settings, creating new admin accounts, or other administrative operations, depending on the victim's role.

MitigationThe vendor has released version 1.1.6 which resolves the vulnerability [1]. Users are strongly advised to update immediately. Patchstack users can enable auto-updates for vulnerable plugins. As a temporary workaround, restrict admin panel access and educate users about phishing risks.
