CVE-2025-59579 affects the Simple Job Board plugin developed by PressTigers, a WordPress plugin used to manage job postings and applications. The vulnerability involves the insertion of sensitive information into data sent by the plugin, allowing remote attackers to retrieve embedded sensitive data without requiring authentication or user interaction. The affected versions include all releases up to and including 2.13.7. The vulnerability is classified under the category of information disclosure, impacting confidentiality but not integrity or availability. The CVSS v3.1 base score is 7.5, with vector AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N, indicating network attack vector, low attack complexity, no privileges or user interaction needed, unchanged scope, and high confidentiality impact. This means an attacker can remotely exploit the vulnerability over the network without any credentials or user action to extract sensitive data embedded in communications sent by the plugin. Although no public exploits have been reported yet, the vulnerability poses a significant risk especially for organizations handling sensitive applicant or HR data. The root cause likely involves improper handling or sanitization of sensitive information before it is transmitted or logged by the plugin, leading to unintended data exposure. Since the plugin is widely used for recruitment purposes, the exposure of personally identifiable information (PII), internal notes, or other confidential data could have serious privacy and compliance implications.

For European organizations, the primary impact is the unauthorized disclosure of sensitive personal and organizational data handled through the Simple Job Board plugin. This could include applicant personal details, resumes, internal HR notes, or other confidential recruitment-related information. Such data leakage can lead to privacy violations under GDPR, resulting in regulatory fines and reputational damage. The vulnerability does not affect data integrity or system availability, but the confidentiality breach alone is critical given the sensitivity of recruitment data. Organizations relying on this plugin for hiring processes are at risk of exposing candidate data to remote attackers without any authentication barrier. This could also facilitate further targeted attacks such as social engineering or identity theft. The absence of known exploits in the wild provides a window for proactive mitigation, but the ease of exploitation (no privileges or user interaction required) means attackers could quickly weaponize this vulnerability once details become public. The impact is amplified for organizations with large volumes of applicant data or those in regulated sectors such as finance, healthcare, or government within Europe.

1. Immediately monitor the vendor’s official channels for patches addressing CVE-2025-59579 and apply them as soon as they become available. 2. Until a patch is released, restrict access to the Simple Job Board plugin’s data endpoints by implementing IP whitelisting or VPN-only access to reduce exposure. 3. Review and audit all data sent or logged by the plugin to identify and remove any embedded sensitive information that should not be transmitted. 4. Implement web application firewall (WAF) rules to detect and block suspicious requests targeting the job board plugin endpoints. 5. Conduct a thorough review of user permissions and minimize the plugin’s data exposure by disabling unnecessary features or integrations that transmit sensitive data. 6. Educate HR and IT teams about the risk and ensure sensitive data handling policies are enforced to reduce the amount of sensitive information processed by the plugin. 7. Monitor network traffic for unusual outbound data flows that may indicate exploitation attempts. 8. Consider alternative job board solutions with stronger security postures if immediate patching is not feasible.
