The vulnerability CVE-2025-60083 affects the PDF Invoice Builder for WooCommerce plugin by add-ons.org. It is caused by unsafe deserialization of untrusted data, which allows an attacker with at least low privileges and no user interaction to perform object injection. The vulnerability impacts all versions up to 6.5.0. The CVSS v3.1 base score is 8.8, indicating a high severity with network attack vector, low attack complexity, requiring low privileges, no user interaction, and resulting in high impact on confidentiality, integrity, and availability.

Successful exploitation of this vulnerability could allow an attacker to execute arbitrary code or manipulate application data, leading to full compromise of the affected system's confidentiality, integrity, and availability. Given the high CVSS score and the nature of object injection, this could result in severe operational and data security consequences for affected WooCommerce installations using this plugin.

No official patch or remediation guidance is currently available from the vendor. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
