CVE-2025-1565 is a path traversal vulnerability classified under CWE-22 found in the Mayosis Core plugin for WordPress, specifically in the file library/wave-audio/peaks/remote_dl.php. This vulnerability allows unauthenticated remote attackers to perform arbitrary file read operations on the affected server by manipulating pathname inputs to escape the intended restricted directory. The plugin fails to properly sanitize or validate the pathname, enabling attackers to traverse directories and access sensitive files such as configuration files, password stores, or other critical data. The vulnerability affects all versions up to and including 5.4.1. The attack vector is network-based, requiring no privileges or user interaction, which increases the risk of automated exploitation. While no public exploits have been reported yet, the vulnerability's nature and ease of exploitation make it a prime target for attackers seeking to gather sensitive information for further attacks or lateral movement. The CVSS v3.1 base score of 7.5 reflects a high severity rating, with a vector string indicating network attack vector, low attack complexity, no privileges required, no user interaction, and high confidentiality impact but no integrity or availability impact. The vulnerability was reserved in February 2025 and published in April 2025, with enrichment from CISA, highlighting its recognized importance in the cybersecurity community.

The primary impact of CVE-2025-1565 is the unauthorized disclosure of sensitive information stored on the affected server. Attackers can read arbitrary files, potentially exposing database credentials, API keys, user data, or other confidential information. This can lead to further compromise, including privilege escalation, data breaches, or targeted attacks against the organization. Since the vulnerability requires no authentication and can be exploited remotely, it poses a significant risk to any organization using the vulnerable Mayosis Core plugin. The confidentiality breach can undermine customer trust, lead to regulatory penalties, and cause operational disruptions if sensitive configuration or system files are exposed. Although the vulnerability does not directly affect system integrity or availability, the information gained can facilitate more damaging attacks. Organizations with public-facing WordPress sites using this plugin are particularly vulnerable, especially if they host sensitive or regulated data.

1. Immediate upgrade: Organizations should update the Mayosis Core plugin to a patched version once released by TeconceTheme. If no patch is available yet, consider temporarily disabling the plugin or the vulnerable component (remote_dl.php) to prevent exploitation. 2. Input validation: Implement strict server-side validation and sanitization of all pathname inputs to ensure directory traversal sequences (e.g., ../) are blocked or properly handled. 3. Web application firewall (WAF): Deploy and configure a WAF with custom rules to detect and block path traversal attempts targeting the remote_dl.php endpoint. 4. Principle of least privilege: Restrict file system permissions for the web server user to limit access to sensitive files, minimizing the impact if exploitation occurs. 5. Monitoring and detection: Enable logging and monitor for unusual access patterns or requests containing traversal sequences targeting the vulnerable script. 6. Network segmentation: Isolate critical systems and sensitive data repositories from web-facing servers to reduce exposure. 7. Incident response readiness: Prepare to respond quickly to any exploitation attempts by having forensic and remediation plans in place. These measures combined will reduce the risk and impact of exploitation until a full patch is applied.
