CVE-2025-62881 identifies a missing authorization vulnerability in WP Lab's WP-Lister Lite for eBay WordPress plugin, affecting all versions up to and including 3.8.3. The vulnerability arises from incorrectly configured access control security levels, allowing users with low privileges (PR:L) to access or perform actions that should be restricted. The CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N) indicates that the attack can be performed remotely over the network with low attack complexity, requires low privileges but no user interaction, and impacts confidentiality only. This means an attacker with a legitimate low-privilege account could exploit the flaw to gain unauthorized access to sensitive information or functionality within the plugin, potentially exposing eBay listing data or other confidential details managed by the plugin. The vulnerability does not affect data integrity or availability, limiting its destructive potential. No public exploits or patches are currently available, but the issue is publicly disclosed and tracked by Patchstack. The plugin is widely used by WordPress sites integrating eBay listings, making it a relevant concern for e-commerce platforms relying on this tool. The lack of proper authorization checks suggests a design or implementation flaw in the plugin's access control mechanisms, which should be addressed by the vendor in future updates.

For European organizations, especially those operating e-commerce websites using WordPress and WP-Lister Lite for eBay, this vulnerability could lead to unauthorized disclosure of sensitive eBay listing data or related business information. Although the impact is limited to confidentiality, exposure of such data can result in competitive disadvantages, leakage of pricing or inventory details, and potential reputational damage. Since the vulnerability requires low privileges but no user interaction, insider threats or compromised low-level accounts could exploit it to escalate access within the plugin's scope. The absence of integrity or availability impact reduces the risk of direct service disruption or data manipulation. However, given the widespread use of WordPress and e-commerce plugins in Europe, the vulnerability could affect numerous small to medium enterprises that rely on this integration, potentially undermining trust in their online sales channels.

Organizations should immediately audit their WordPress installations to identify if WP-Lister Lite for eBay versions up to 3.8.3 are in use. Until a vendor patch is released, restrict access to the plugin's functionality by tightening user roles and permissions, ensuring only trusted users have accounts with privileges that could exploit this vulnerability. Implement network-level controls such as IP whitelisting or VPN access for administrative interfaces to reduce exposure. Monitor logs for unusual access patterns or attempts to access restricted plugin features. Engage with WP Lab or Patchstack for updates and apply patches promptly once available. Consider alternative plugins or custom solutions with verified access control if immediate patching is not feasible. Regularly review and update WordPress and plugin security configurations to prevent similar issues.
