CVE-2025-62881 identifies a Missing Authorization vulnerability in the WP-Lister Lite for eBay WordPress plugin developed by WP Lab, affecting all versions up to and including 3.8.3. This vulnerability arises from improperly configured access control mechanisms within the plugin, allowing users with limited privileges (PR:L) to perform actions or access data that should be restricted. The vulnerability is exploitable remotely over the network (AV:N) without requiring user interaction (UI:N), which increases the risk of automated or remote exploitation. The CVSS 3.1 base score is 4.3 (medium severity), reflecting a low impact on confidentiality (C:L), no impact on integrity (I:N) or availability (A:N), and low attack complexity (AC:L). The plugin is commonly used to integrate eBay listings into WordPress sites, primarily by small to medium-sized e-commerce businesses. The missing authorization could lead to unauthorized data exposure or manipulation of eBay listing configurations, potentially resulting in leakage of sensitive business information or disruption of listing management workflows. No known exploits have been reported in the wild, and no official patches have been linked at the time of publication. The vulnerability was reserved on October 24, 2025, and published on October 27, 2025, indicating recent discovery. Organizations relying on this plugin should prioritize reviewing user permissions and monitoring for updates from WP Lab.

For European organizations, the impact of CVE-2025-62881 primarily concerns confidentiality risks, as unauthorized users with low privileges could access sensitive e-commerce data or configuration settings related to eBay listings. This could lead to exposure of business-sensitive information such as pricing strategies, inventory levels, or customer data linked to eBay sales. Although integrity and availability are not directly affected, unauthorized access could indirectly disrupt business operations or erode trust if sensitive information is leaked. Small and medium enterprises (SMEs) using WordPress and eBay integrations are particularly vulnerable, as they may lack robust internal access controls or monitoring. The medium severity rating suggests that while the risk is not critical, it should not be ignored, especially in regulated sectors such as finance, retail, or data protection-sensitive industries under GDPR. The absence of known exploits reduces immediate risk but does not preclude targeted attacks, especially as threat actors often focus on e-commerce platforms. Organizations in Europe with significant e-commerce presence or those acting as eBay sellers should consider this vulnerability a moderate risk to their operational security and data confidentiality.

To mitigate CVE-2025-62881, European organizations should take the following specific actions: 1) Immediately audit and restrict user roles and permissions within WordPress to ensure that only trusted users have access to the WP-Lister Lite plugin functionalities, minimizing exposure to low-privilege exploitation. 2) Implement custom access control rules or use security plugins that enforce stricter authorization checks around eBay listing management features. 3) Monitor network and application logs for unusual access patterns or unauthorized attempts to interact with the plugin interfaces. 4) Engage with WP Lab or official plugin channels to track the release of patches or updates addressing this vulnerability and apply them promptly. 5) Consider temporarily disabling the WP-Lister Lite plugin if the risk outweighs the operational need until a patch is available. 6) Educate internal teams about the risks of privilege escalation and missing authorization vulnerabilities to improve overall security hygiene. 7) For organizations with compliance requirements, document mitigation steps and risk assessments related to this vulnerability to support audit readiness. These measures go beyond generic advice by focusing on role-based access control, active monitoring, and vendor engagement specific to this plugin and vulnerability.
