A malicious actor can manipulate the tip amount for an order, applying an excessive or even negative amount. This manipulation can result in unauthorized discounts up to free orders depending on the value submitted by the attacker. Since the vulnerability does not require authentication, it can be exploited by anyone who can interact with the network.<\/p>\n<p><strong>Conceptual Example Code<\/strong><\/p><div id=\"ameeb-2015910023\" class=\"ameeb-content ameeb-entity-placement\"><div class=\"poptin-embedded\" data-id=\"f6b387694f681\"><\/div>\r\n\r\n\r\n\r\n\r\n\r\n<\/div>\n<p>Here is a conceptual example of how the vulnerability might be exploited:<\/p>\n<pre><code class=\"\" data-line=\"\">POST \/checkout HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/json\n{\n&quot;order&quot;: {\n&quot;items&quot;: [...],\n&quot;payment&quot;: {\n&quot;method&quot;: &quot;credit_card&quot;,\n...\n},\n&quot;tip&quot;: {\n&quot;data-tip&quot;: &quot;-10000&quot;\n}\n}\n}<\/code><\/pre>\n<p>In this example, the attacker is placing an order and setting a negative tip value (`&#8221;data-tip&#8221;: &#8220;-10000&#8243;`). Since there&#8217;s no server-side validation, the application subtracts this tip from the total order amount, effectively giving the attacker a large discount on their order.<\/p>\n<p><strong>Mitigation Measures<\/strong><\/p>\n<p>To mitigate the risk posed by this vulnerability, users of the affected plugin are advised to apply the vendor patch as soon as it becomes available. In the meantime, the use of a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) could serve as a temporary mitigation strategy, providing an additional layer of security against potential exploitation.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Overview The CVE-2025-6025 is a significant cybersecurity vulnerability affecting the Order Tip for WooCommerce plugin for WordPress.
