CVE-2025-48334 is a Missing Authorization vulnerability (CWE-862) identified in the WordPress plugin Woo Slider Pro developed by BinaryCarpenter. The vulnerability affects the action "woo_slide_pro_delete_slider" and is present in versions up to 1.12. This flaw arises due to incorrectly configured access control security levels, allowing users with limited privileges (requiring at least some level of authentication) to perform unauthorized deletion of sliders. The CVSS 3.1 base score is 6.5 (medium severity), with the vector indicating network attack vector (AV:N), low attack complexity (AC:L), requiring privileges (PR:L), no user interaction (UI:N), unchanged scope (S:U), no confidentiality or integrity impact (C:N/I:N), but high impact on availability (A:H). This means an authenticated user with limited privileges can delete slider content, potentially disrupting website functionality or user experience by removing visual elements critical for site navigation or marketing. No known exploits are reported in the wild yet, and no patches have been linked at the time of publication. The vulnerability highlights a failure in enforcing proper authorization checks before allowing deletion operations, which could be exploited by malicious insiders or compromised accounts to degrade site availability.

For European organizations using Woo Slider Pro on WordPress sites, this vulnerability could lead to denial of service conditions on their websites by unauthorized deletion of slider elements, which are often used for key promotional content or navigation. This can degrade user experience, damage brand reputation, and potentially impact revenue streams, especially for e-commerce or marketing-heavy sites. Since the vulnerability requires at least some level of authentication, the risk is higher in environments where user accounts have weak credential management or where insider threats exist. The lack of confidentiality and integrity impact reduces the risk of data leakage or tampering, but availability impact can still cause significant operational disruption. Organizations in sectors such as retail, media, and services that rely on WordPress for customer engagement are particularly at risk. Additionally, the absence of a patch increases exposure duration, necessitating immediate mitigation.

European organizations should immediately audit user roles and permissions within WordPress to ensure that only fully trusted users have access to slider management functions. Implement strict role-based access control (RBAC) to limit who can perform deletion actions. Employ multi-factor authentication (MFA) to reduce risk from compromised credentials. Monitor logs for unusual deletion attempts or activity related to the "woo_slide_pro_delete_slider" action. If possible, temporarily disable or restrict the Woo Slider Pro plugin until a vendor patch is released. Consider deploying web application firewalls (WAFs) with custom rules to detect and block unauthorized deletion requests targeting this action. Regularly back up website content and configurations to enable quick restoration in case of malicious deletions. Engage with the plugin vendor or community for updates and patches, and apply them promptly once available.
