CVE-2025-58978 is a medium-severity vulnerability classified under CWE-862 (Missing Authorization) affecting the WP Swings PDF Generator plugin for WordPress, specifically versions up to 1.5.4. This vulnerability arises due to improperly configured access control mechanisms within the plugin, allowing unauthorized users to exploit functionality that should be restricted. The vulnerability does not require authentication (PR:N) nor user interaction (UI:N), and can be exploited remotely over the network (AV:N) with low attack complexity (AC:L). The impact is limited to confidentiality (C:L) with no effect on integrity or availability. Essentially, an attacker can access or retrieve PDF generation resources or data that should be protected, potentially exposing sensitive information. Since the vulnerability affects a WordPress plugin, it targets websites using this plugin for PDF generation, which may include business, governmental, or personal sites. No known exploits are currently reported in the wild, and no patches have been linked yet, indicating the need for vigilance and proactive mitigation. The vulnerability's CVSS score of 5.3 reflects a moderate risk primarily due to unauthorized data disclosure without further system compromise.

For European organizations, this vulnerability poses a risk of unauthorized data exposure through websites using the WP Swings PDF Generator plugin. Organizations relying on this plugin for document generation may inadvertently leak sensitive or confidential information embedded in PDFs or related resources. This can lead to privacy violations, regulatory non-compliance (e.g., GDPR), reputational damage, and potential legal consequences. Since the vulnerability does not affect integrity or availability, the threat is primarily data confidentiality loss. However, given the widespread use of WordPress in Europe across various sectors including SMEs, public institutions, and e-commerce, the potential for data leakage is significant. Attackers could leverage this vulnerability to harvest sensitive documents or information without needing credentials or user interaction, increasing the risk profile. The absence of known exploits suggests a window for mitigation before active exploitation occurs.

European organizations should immediately inventory their WordPress installations to identify the presence of the WP Swings PDF Generator plugin and its version. Until an official patch is released, organizations should consider disabling or uninstalling the plugin if it is not critical to operations. For sites requiring PDF generation, alternative secure plugins with verified access controls should be evaluated. Web application firewalls (WAFs) can be configured to monitor and block suspicious requests targeting the plugin endpoints. Additionally, organizations should implement strict access control policies at the web server and application level, including IP whitelisting or authentication requirements where feasible. Regular security audits and monitoring of web logs for anomalous access patterns related to PDF generation endpoints are recommended. Once a patch is available, prompt application of updates is essential. Finally, organizations should review and reinforce their data handling and privacy policies to minimize sensitive data exposure through web applications.
