CVE-2025-1310 is a directory traversal vulnerability identified in the blueglassch Job Postings plugin for WordPress, affecting all versions up to and including 2.7.11. The vulnerability stems from improper limitation of a pathname to a restricted directory (CWE-22), allowing authenticated users with Subscriber-level privileges or higher to manipulate the 'job_postings_get_file' parameter to access arbitrary files on the server. This flaw enables attackers to bypass intended directory restrictions and read sensitive files, potentially exposing configuration files, credentials, or other confidential data stored on the web server. The vulnerability does not require user interaction beyond authentication, and the attack vector is network-based, with low attack complexity. The CVSS v3.1 base score is 6.5 (medium severity), reflecting high confidentiality impact but no impact on integrity or availability. No public exploits have been reported yet, but the vulnerability poses a significant risk to WordPress sites using this plugin, especially those that allow Subscriber-level user registrations. The root cause is insufficient input validation and sanitization of the file path parameter, which fails to restrict directory traversal sequences such as '../'. This vulnerability highlights the importance of secure coding practices in plugin development and the need for strict access controls on file retrieval functions. Organizations should monitor for updates or patches from the vendor and consider temporary mitigations such as restricting authenticated user capabilities or disabling the vulnerable functionality until fixed.

The primary impact of CVE-2025-1310 is unauthorized disclosure of sensitive information due to arbitrary file read capabilities. Attackers with low-level authenticated access can exploit this to access configuration files, database credentials, or other sensitive data stored on the server, which can facilitate further attacks such as privilege escalation, data exfiltration, or lateral movement within the network. Although the vulnerability does not allow code execution or direct modification of data, the confidentiality breach can have severe consequences, including exposure of user data, intellectual property, or internal system details. Organizations running WordPress sites with the affected plugin are at risk of data leakage, reputational damage, and compliance violations. The ease of exploitation by low-privileged users increases the threat surface, especially for sites that allow open registrations. The lack of known exploits in the wild currently reduces immediate risk but does not eliminate the potential for future attacks once exploit code becomes available. Overall, the vulnerability poses a medium-level risk with significant confidentiality impact but limited direct impact on system integrity or availability.

To mitigate CVE-2025-1310, organizations should take the following specific actions: 1) Immediately restrict or disable the vulnerable 'job_postings_get_file' functionality if possible, especially for Subscriber-level users. 2) Implement strict input validation and sanitization on the 'job_postings_get_file' parameter to prevent directory traversal sequences such as '../'. 3) Apply the official patch or update from blueglassch as soon as it becomes available to fix the vulnerability at the source. 4) Review and tighten WordPress user role permissions to limit file access capabilities for low-privileged users. 5) Monitor web server logs for suspicious file access patterns indicative of directory traversal attempts. 6) Employ web application firewalls (WAFs) with rules to detect and block directory traversal payloads targeting this plugin. 7) Conduct regular security audits of WordPress plugins and remove or replace those that are unmaintained or vulnerable. 8) Educate site administrators about the risks of allowing open user registrations without proper controls. These targeted measures go beyond generic advice by focusing on the specific vulnerable parameter, user roles, and plugin context.
