CVE-2025-49246 is a security vulnerability classified under CWE-862, indicating a Missing Authorization issue in the cmoreira Testimonials Showcase plugin. This vulnerability arises due to incorrectly configured access control security levels, which allow an attacker with limited privileges (PR:L - Privileges Required: Low) to perform unauthorized actions that should be restricted. The vulnerability affects the Testimonials Showcase product up to version 1.9.16, though specific affected versions are not detailed. The vulnerability does not require user interaction (UI:N) and can be exploited remotely over the network (AV:N). The impact is limited to integrity (I:L) with no confidentiality or availability impact. This means an attacker can modify or manipulate testimonial data or related content without proper authorization but cannot access confidential information or disrupt service availability. The CVSS score is 4.3, indicating a low severity level. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability's root cause is an access control misconfiguration, which is a common security issue where authorization checks are missing or improperly implemented, allowing unauthorized users to perform actions beyond their intended permissions. Since the vulnerability requires low privileges, it could be exploited by authenticated users with minimal access, potentially including registered users or contributors, depending on the system's role definitions.

For European organizations using the cmoreira Testimonials Showcase plugin, this vulnerability could lead to unauthorized modification of testimonial content, which may affect the integrity and trustworthiness of displayed user feedback or endorsements. While this does not directly compromise sensitive data or system availability, it can damage brand reputation and user trust if testimonials are altered maliciously. Organizations relying on testimonials for marketing or customer engagement could face reputational risks. Additionally, if testimonial content is used in automated decision-making or displayed prominently on websites, unauthorized changes could mislead customers or stakeholders. Since the vulnerability requires low privileges, insider threats or compromised low-level accounts could exploit this issue. The lack of known exploits in the wild reduces immediate risk, but the absence of patches means organizations must proactively address the issue to prevent future exploitation.

European organizations should immediately review and audit access control configurations within the Testimonials Showcase plugin, ensuring that authorization checks are correctly implemented for all actions related to testimonial management. Restrict testimonial modification capabilities strictly to trusted roles and verify that no low-privilege users can perform unauthorized changes. Until an official patch is released, consider disabling or limiting the plugin's functionality to reduce exposure. Employ web application firewalls (WAFs) with custom rules to detect and block suspicious requests targeting testimonial modification endpoints. Monitor logs for unusual activity related to testimonial content changes, especially from low-privilege accounts. Additionally, implement strong authentication and role management policies to minimize the risk of account compromise. Stay updated with vendor announcements for patches or updates addressing this vulnerability and apply them promptly once available.
