CVE-2025-58872 is a vulnerability classified under CWE-201, which involves the insertion of sensitive information into sent data within the premiumbizthemes Simple Price Calculator plugin. This vulnerability affects versions up to 1.3 of the Simple Price Calculator product. The issue allows an attacker with at least low privileges (PR:L) to retrieve embedded sensitive data that is unintentionally included in data sent by the plugin. The vulnerability does not require user interaction (UI:N) and can be exploited remotely over the network (AV:N) with low attack complexity (AC:L). The scope is unchanged (S:U), meaning the impact is limited to the vulnerable component itself. The confidentiality impact is high (C:H), indicating that sensitive information can be exposed, but there is no impact on integrity (I:N) or availability (A:N). The CVSS 3.1 base score is 6.5, categorizing this as a medium severity vulnerability. No known exploits are currently reported in the wild, and no patches have been published yet. The vulnerability likely stems from the plugin embedding sensitive data such as credentials, tokens, or private configuration details into outgoing data streams, which can be intercepted or accessed by unauthorized parties. This can lead to information disclosure that may facilitate further attacks or unauthorized access.

For European organizations using the premiumbizthemes Simple Price Calculator plugin, this vulnerability poses a significant risk to confidentiality. Sensitive business or customer data embedded in the plugin's sent data could be exposed to attackers, potentially leading to data breaches or leakage of proprietary information. Since the vulnerability does not affect integrity or availability, direct disruption of services is unlikely. However, the exposure of sensitive data could undermine trust, lead to regulatory non-compliance (e.g., GDPR violations), and result in financial penalties or reputational damage. Organizations in sectors handling sensitive customer or financial data, such as e-commerce, finance, or healthcare, may be particularly impacted. The requirement for low privileges means that an attacker might exploit this vulnerability from a compromised or low-level user account, increasing the risk if internal threat actors or phishing attacks are successful.

European organizations should immediately audit their use of the premiumbizthemes Simple Price Calculator plugin to determine if they are running affected versions. Until an official patch is released, organizations should consider the following mitigations: 1) Restrict access to the plugin and its data transmission channels to trusted users only, minimizing the risk of low-privilege exploitation. 2) Monitor network traffic for unusual data transmissions that may contain sensitive information, using data loss prevention (DLP) tools. 3) Implement strict access controls and segmentation to limit exposure of systems running the vulnerable plugin. 4) If feasible, temporarily disable or replace the Simple Price Calculator plugin with alternative solutions that do not expose sensitive data. 5) Prepare for patch deployment by subscribing to vendor updates and security advisories. 6) Conduct internal security awareness training to reduce the risk of credential compromise that could facilitate exploitation. These steps go beyond generic advice by focusing on access restriction, monitoring, and temporary mitigation until a patch is available.
