CVE-2025-47510 is a high-severity vulnerability classified under CWE-98, which involves improper control of filenames used in include or require statements within PHP programs. Specifically, this vulnerability affects the 'Display Eventbrite Events' product by fullworks. The flaw allows for PHP Local File Inclusion (LFI), meaning an attacker can manipulate the filename parameter to include arbitrary files from the local server filesystem. This can lead to disclosure of sensitive information, code execution, or further exploitation depending on the files accessible and the server configuration. The vulnerability has a CVSS 3.1 base score of 7.5, indicating a high impact with network attack vector, high confidentiality, integrity, and availability impacts, but requiring low privileges and high attack complexity without user interaction. Although the affected versions are not explicitly specified, the vulnerability is confirmed and published as of May 7, 2025. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability arises from insufficient validation or sanitization of input controlling the filename in include/require statements, allowing attackers to traverse directories or specify unintended files. This can lead to sensitive data exposure, remote code execution if combined with other vulnerabilities, or denial of service by including malicious or malformed files.

For European organizations using the 'Display Eventbrite Events' PHP plugin or software, this vulnerability poses significant risks. Exploitation could lead to unauthorized disclosure of sensitive internal files, including configuration files, credentials, or source code, compromising confidentiality. Integrity and availability could also be impacted if attackers manage to execute arbitrary code or disrupt service availability by including malicious files. Organizations relying on this plugin for event display on websites may face website defacement, data breaches, or service outages. Given the network attack vector and lack of user interaction requirement, attackers can remotely exploit this vulnerability, increasing the risk of widespread impact. The high attack complexity somewhat limits exploitation to skilled attackers with some level of access, but the low privilege requirement means that even low-level authenticated users could potentially exploit it. This is particularly concerning for European companies in sectors with strict data protection regulations (e.g., GDPR), where data breaches can lead to heavy fines and reputational damage. Additionally, event management platforms are often integrated with customer-facing websites, increasing the potential exposure to external attackers.

1. Immediate code review and sanitization: Developers should audit all include/require statements in the 'Display Eventbrite Events' codebase to ensure that filenames are strictly validated against a whitelist of allowed files or paths, preventing directory traversal or arbitrary file inclusion. 2. Implement input validation: Use robust input validation and sanitization techniques to ensure that user-controlled inputs cannot influence file paths. 3. Apply principle of least privilege: Run PHP processes with minimal permissions to limit access to sensitive files, reducing the impact of potential LFI exploitation. 4. Monitor and restrict file system access: Employ web application firewalls (WAFs) and intrusion detection systems (IDS) to detect and block suspicious requests attempting file inclusion attacks. 5. Patch management: Stay alert for official patches or updates from fullworks and apply them promptly once available. 6. Disable unnecessary PHP functions: Functions like include(), require(), and their variants should be used cautiously; consider disabling dangerous PHP functions if not needed. 7. Logging and alerting: Enable detailed logging of web requests and monitor for anomalous patterns indicative of LFI attempts. 8. Segmentation: Isolate the web server hosting this plugin from critical internal systems to contain potential breaches.
