Attack Vectors

Shopire (slug: shopire) versions 1.0.57 and earlier have a Medium-severity vulnerability (CVSS 4.3, CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N) tracked as CVE-2025-13091. An attacker must have an authenticated WordPress account with Subscriber-level access or higher, which can occur through compromised credentials, reused passwords from another breach, an overly permissive registration workflow, or a legitimate low-privilege account.

Once logged in, the attacker can trigger a theme function that installs a specific plugin (fable-extra) without the proper authorization check. This does not require user interaction, which increases the likelihood of success if a low-privilege account is obtained.

Security Weakness

The root issue is a missing capability (authorization) check in the shopire_admin_install_plugin() function. In practical terms, the theme does not consistently verify that the logged-in user has the appropriate administrative permissions before performing a sensitive action (installing a plugin).

For business leaders and compliance teams, this is a governance problem as much as a technical one: it undermines the separation of duties within WordPress by allowing low-privilege accounts to change the site’s configuration in a way that should be restricted to administrators.

Technical or Business Impacts

Unauthorized change control: Installing the fable-extra plugin without proper approval can introduce unreviewed code and functionality into a production website. Even when the plugin is not inherently malicious, it expands the site’s “attack surface” and may create new security, privacy, or stability risks over time.

Brand and revenue exposure: Marketing sites and eCommerce experiences rely on trust and uptime. Unapproved changes can lead to unexpected site behavior, content issues, or performance degradation that impacts conversion rates, campaign launches, and customer confidence.

Compliance and audit risk: If your organization must meet internal controls or external requirements, unauthorized software changes can create audit findings—especially if administrative actions can be performed by accounts intended to be low-risk (Subscriber+). Demonstrating strong access controls and change-management practices is often a key expectation for compliance stakeholders.

Remediation: Update Shopire to version 1.0.58 or a newer patched version. Also review Subscriber-level accounts (including inactive users), require strong authentication practices, and ensure only authorized roles can install plugins.

Similar Attacks

Access-control failures and “missing authorization” issues are a recurring theme in WordPress security, because they allow lower-privilege accounts to perform actions reserved for administrators. Here are a few well-known examples:
