CVE-2025-48247 is a Missing Authorization vulnerability (CWE-862) identified in the WordPress plugin 'Shortlinks by Pretty Links' developed by Blair Williams. This vulnerability affects versions up to 3.6.15 of the plugin. The core issue arises from incorrectly configured access control security levels, allowing users with limited privileges (requiring at least low-level privileges) to perform actions or access resources that should be restricted. Specifically, the vulnerability does not require user interaction and can be exploited remotely over the network (AV:N), with low attack complexity (AC:L). The vulnerability impacts the integrity of the system by allowing unauthorized modification or manipulation of shortlinks or related data, but it does not affect confidentiality or availability. The CVSS v3.1 base score is 4.3, categorizing it as a medium severity issue. No known exploits are currently reported in the wild, and no official patches or updates have been linked yet. The vulnerability is significant because WordPress plugins like Pretty Links are widely used to manage URL redirection and tracking, which are critical for marketing and operational workflows. Exploitation could lead to unauthorized changes in link destinations, potentially redirecting users to malicious sites or disrupting business processes dependent on accurate link management.

For European organizations, this vulnerability poses a moderate risk primarily to the integrity of web assets and marketing infrastructure. Organizations relying on the Pretty Links plugin for managing shortlinks on their WordPress sites could face unauthorized manipulation of URLs, which may lead to reputational damage, loss of customer trust, or indirect financial losses if users are redirected to malicious or competitor sites. While the vulnerability does not directly compromise sensitive data confidentiality or cause service outages, the integrity breach could facilitate phishing campaigns or fraud. Given the widespread use of WordPress in Europe across SMEs and large enterprises, especially in sectors like e-commerce, media, and marketing agencies, the risk is non-negligible. The absence of known exploits reduces immediate threat but should not lead to complacency. Attackers with low privileges inside the system could leverage this flaw to escalate their impact, making internal threat actors or compromised accounts a concern. The vulnerability's network-exploitable nature also means external attackers might exploit weakly protected accounts to trigger unauthorized actions.

European organizations using the Pretty Links plugin should immediately audit user roles and permissions to ensure that only trusted users have access to functionalities related to shortlink management. Implement strict access controls and monitor for unusual changes in shortlink configurations. Since no official patch is currently available, consider temporarily disabling the plugin or restricting its use to administrators until a fix is released. Employ web application firewalls (WAFs) with custom rules to detect and block suspicious requests targeting Pretty Links endpoints. Regularly review WordPress and plugin updates from the vendor and apply patches promptly once available. Additionally, implement multi-factor authentication (MFA) for all WordPress accounts to reduce the risk of privilege abuse. Conduct security awareness training for administrators and users with elevated privileges to recognize potential misuse. Finally, maintain comprehensive logging and alerting on changes to shortlinks to enable rapid detection and response to unauthorized modifications.
