CVE-2025-69352 identifies a Missing Authorization vulnerability in StellarWP's The Events Calendar WordPress plugin, affecting versions up to 6.15.12.2. This vulnerability arises from incorrectly configured access control security levels, allowing users with limited privileges (PR:L) to perform unauthorized actions without user interaction (UI:N). The CVSS vector indicates network attack vector (AV:N), low attack complexity (AC:L), and no impact on availability (A:N), but with low confidentiality (C:L) and integrity (I:L) impacts. Essentially, an attacker who has some level of authenticated access can exploit this flaw to bypass authorization checks, potentially accessing or modifying event data they should not have permissions for. The vulnerability does not require user interaction and can be exploited remotely, increasing its risk profile. No known exploits are currently reported in the wild, but the issue is publicly disclosed and should be addressed promptly. The lack of patches at the time of reporting suggests organizations must monitor vendor updates closely. The vulnerability's root cause is an access control misconfiguration, a common security weakness that can lead to privilege escalation or data leakage if not properly managed.

For European organizations, the impact primarily involves unauthorized disclosure and modification of event-related data managed through The Events Calendar plugin. This could lead to leakage of sensitive scheduling information, manipulation of event details, or disruption of event management workflows. While availability is not affected, the integrity and confidentiality impacts could undermine trust in organizational communications and event planning. Organizations relying heavily on public-facing or internal event calendars may experience reputational damage or operational inefficiencies. Given the medium severity, the threat is moderate but significant enough to warrant prompt remediation. The risk is heightened in sectors where event data is sensitive, such as government, education, and large enterprises. Additionally, attackers leveraging this vulnerability could use it as a foothold for further attacks within the network if combined with other vulnerabilities or misconfigurations.

Organizations should immediately audit their use of The Events Calendar plugin and verify the version in use, upgrading to the latest patched version once available from StellarWP. In the absence of a patch, administrators should review and tighten access control settings within the plugin and WordPress roles to ensure minimal privilege principles are enforced. Restrict plugin management and event editing capabilities to trusted users only. Implement monitoring and alerting for unusual access patterns or unauthorized changes to event data. Consider deploying web application firewalls (WAFs) with custom rules to detect and block suspicious requests targeting the plugin endpoints. Regularly back up event data to enable recovery in case of unauthorized modifications. Stay informed through vendor advisories and security communities for updates or exploit reports. Finally, conduct security awareness training for administrators managing WordPress plugins to prevent misconfigurations.
