CVE-2025-1770 is a path traversal vulnerability classified under CWE-22, found in the Eventin – Event Manager, Events Calendar, Event Tickets and Registrations plugin for WordPress, affecting all versions up to and including 4.0.24. The vulnerability arises from improper limitation of a pathname to a restricted directory via the 'style' parameter, which is susceptible to Local File Inclusion (LFI). Authenticated attackers with Contributor-level privileges or higher can exploit this flaw to include arbitrary files on the server. This inclusion can lead to execution of arbitrary PHP code embedded within those files, effectively allowing attackers to escalate privileges, bypass access controls, and compromise the confidentiality, integrity, and availability of the affected system. The vulnerability does not require user interaction beyond authentication, and the attack vector is network-based, making it remotely exploitable. The CVSS v3.1 base score is 8.8, indicating high severity, with metrics reflecting network attack vector, low attack complexity, required privileges at the contributor level, no user interaction, and high impact on confidentiality, integrity, and availability. Although no known exploits are currently in the wild, the vulnerability poses a significant risk due to the widespread use of WordPress and this plugin in event management scenarios. The lack of available patches at the time of disclosure necessitates immediate mitigation efforts by affected organizations.

The impact of CVE-2025-1770 is substantial for organizations using the Eventin WordPress plugin. Successful exploitation can lead to arbitrary code execution on the web server, enabling attackers to fully compromise the affected system. This includes the ability to bypass access controls, access sensitive data such as user information and event details, and potentially pivot to other internal systems. The vulnerability undermines the confidentiality, integrity, and availability of the affected WordPress sites. Given that Contributor-level access is sufficient for exploitation, attackers who gain limited user credentials or compromise accounts with such privileges can escalate their control significantly. This threat is particularly critical for organizations relying on WordPress for event management, ticketing, and registrations, including businesses, educational institutions, and event organizers. The potential for data breaches, service disruption, and reputational damage is high, and remediation delays could lead to exploitation once public exploits emerge.

To mitigate CVE-2025-1770, organizations should immediately upgrade the Eventin plugin to a patched version once available. Until a patch is released, restrict Contributor-level and higher privileges to trusted users only, minimizing the risk of exploitation. Implement strict file upload validation and sanitization policies to prevent malicious files from being uploaded. Employ Web Application Firewalls (WAFs) with custom rules to detect and block attempts to exploit the 'style' parameter for path traversal or LFI attacks. Monitor logs for suspicious activity related to file inclusion or unexpected PHP execution. Consider isolating WordPress instances with this plugin in segmented network zones to limit lateral movement if compromised. Regularly audit user roles and permissions to ensure least privilege principles are enforced. Additionally, maintain up-to-date backups and have an incident response plan ready to address potential compromises swiftly.
