Attack Vectors
Page and Post Clone (slug: page-or-post-clone) has a Medium-severity vulnerability (CVSS 6.5) tracked as CVE-2026-2893. The issue affects all versions up to and including 6.3.
The primary attack path is through a WordPress user account with at least Contributor permissions. An authenticated attacker can abuse the meta_key parameter involved in the plugin’s cloning workflow to influence database queries. Because this is a second-order SQL injection, the harmful input can be stored first and then later executed when the clone-related functionality processes it.
For business leaders, the key takeaway is that this does not require an external attacker to “break in” directly; it can be triggered by someone who already has a lower-level account (or by an attacker who compromises one), and it can operate quietly without needing user clicks.
Security Weakness
The vulnerability stems from insufficient escaping of a user-supplied value and insufficient SQL query preparation in the plugin’s content_clone() function when handling meta_key. In practical terms, this weakness can allow an attacker to append malicious database instructions into an otherwise legitimate query.
Because the injection is second-order, traditional “front door” filters or reviews may miss it: the payload is stored and only becomes dangerous when it is later used by the plugin’s cloning process. This increases the risk of delayed discovery and makes incident timelines harder to reconstruct for compliance reporting.
Technical or Business Impacts
The CVSS vector indicates a meaningful risk to confidentiality (C:H) with a low barrier to execution once an attacker has Contributor-level access. The most direct impact is potential exposure of sensitive information from the WordPress database, which may include business data and other stored content depending on the site’s configuration and integrations.
From a business-risk perspective, data exposure can trigger regulatory and contractual obligations, including breach notifications, audits, and customer or partner inquiries. It can also lead to brand and revenue impact if stakeholders lose confidence in the organization’s ability to protect data, especially for marketing-led sites that collect leads, run campaigns, or connect to third-party analytics and CRM platforms.
Remediation: Update Page and Post Clone to version 6.4 or newer (patched). If immediate patching is not possible, reduce risk by limiting Contributor-level access, reviewing user accounts, and ensuring strong authentication controls until the update is completed.
