CVE-2025-62027 identifies a missing authorization vulnerability in the StellarWP Event Tickets WordPress plugin, affecting versions up to and including 5.26.3. This flaw arises because the plugin fails to properly verify whether a user has the necessary permissions before allowing certain actions, leading to unauthorized access or modifications. The vulnerability is exploitable remotely over the network (AV:N) with low attack complexity (AC:L), requiring only low privileges (PR:L) and no user interaction (UI:N). The scope is unchanged (S:U), meaning the impact is confined to the vulnerable component. The vulnerability impacts confidentiality and integrity (C:L/I:L) but does not affect availability (A:N). Although no known exploits have been reported in the wild, the nature of the flaw could allow attackers to access or alter sensitive event-related data, such as ticket information or user details, potentially leading to data leakage or unauthorized event management actions. The plugin is widely used in WordPress-based event management sites, making the vulnerability relevant to organizations relying on this software for ticketing and event coordination. The absence of patches at the time of reporting necessitates proactive monitoring and interim protective measures.

For European organizations, especially those operating event management platforms or websites using the StellarWP Event Tickets plugin, this vulnerability poses a risk of unauthorized data access and modification. Confidentiality impacts could lead to exposure of attendee information, ticket details, or event logistics, potentially violating data protection regulations such as GDPR. Integrity impacts may allow attackers to alter ticket availability or event data, disrupting operations and causing financial or reputational damage. While availability is not directly affected, the indirect consequences of data manipulation could impair service reliability. Organizations in sectors with frequent event activities—such as entertainment, conferences, and cultural institutions—may face operational disruptions. Additionally, failure to remediate could increase exposure to targeted attacks exploiting this vulnerability to gain footholds or escalate privileges within web infrastructure.

Organizations should prioritize updating the StellarWP Event Tickets plugin to the latest patched version once it becomes available. Until patches are released, implement strict access controls by limiting plugin management capabilities to trusted administrators only. Employ web application firewalls (WAFs) with custom rules to detect and block suspicious requests targeting the plugin’s endpoints. Conduct thorough audits of user permissions to ensure no unnecessary privileges are granted. Monitor logs for unusual activity related to event ticket management functions. Consider temporarily disabling the plugin if it is not critical to operations or if risk tolerance is low. Engage with the vendor and security communities for updates and apply security best practices for WordPress environments, including regular backups and segmentation of administrative interfaces.
