CVE-2025-59579 is a vulnerability identified in the Simple Job Board plugin developed by PressTigers, affecting all versions up to and including 2.13.7. The core issue involves the insertion of sensitive information into data sent by the plugin, which can be retrieved by an attacker without requiring any authentication or user interaction. This vulnerability is classified under the category of information disclosure, where confidential data embedded in outbound communications can be intercepted or accessed remotely. The CVSS 3.1 base score of 7.5 reflects the high impact on confidentiality (C:H), with no impact on integrity or availability. The attack vector is network-based (AV:N), with low attack complexity (AC:L), and no privileges required (PR:N). The vulnerability is unscoped (S:U), meaning it affects resources beyond the immediate security scope. No known exploits are currently reported in the wild, but the potential for data leakage is significant, especially in environments where the plugin handles sensitive recruitment or personal data. The lack of patches at the time of reporting necessitates immediate risk mitigation strategies. The vulnerability likely arises from improper sanitization or encryption of sensitive fields before transmission, allowing attackers to retrieve embedded data from network traffic or application responses. This flaw could be exploited by attackers to harvest personal identifiable information (PII), candidate details, or other confidential data managed by the job board plugin, leading to privacy violations and regulatory non-compliance.

For European organizations, the impact of CVE-2025-59579 is primarily on the confidentiality of sensitive recruitment and candidate data. Exposure of such data can lead to privacy breaches, reputational damage, and potential violations of the EU General Data Protection Regulation (GDPR), which mandates strict controls on personal data processing and breach notifications. Organizations using Simple Job Board for managing job applications and candidate information may inadvertently expose PII to unauthorized parties, including attackers on the network or malicious insiders. This can result in legal penalties, loss of trust from applicants, and operational disruptions if remediation requires taking systems offline. Additionally, sectors with high recruitment activity such as technology, finance, and government agencies in Europe may face targeted exploitation attempts. The vulnerability does not affect system integrity or availability directly but can serve as a stepping stone for further attacks if sensitive credentials or information are leaked. The ease of exploitation without authentication increases the risk profile, making it a critical concern for organizations relying on this plugin for their hiring processes.

1. Monitor PressTigers’ official channels and Patchstack for the release of security patches addressing CVE-2025-59579 and apply them immediately upon availability. 2. Until patches are released, restrict access to the Simple Job Board plugin interfaces by implementing network segmentation and firewall rules to limit exposure to trusted IP addresses only. 3. Conduct a thorough audit of data transmitted by the plugin to identify and remove or encrypt any sensitive information embedded in outbound communications. 4. Employ web application firewalls (WAFs) with custom rules to detect and block suspicious requests targeting the job board endpoints. 5. Review and enhance logging and monitoring to detect unusual access patterns or data exfiltration attempts related to the plugin. 6. Educate HR and IT teams about the risks associated with the plugin and enforce strict data handling policies for recruitment data. 7. Consider temporary alternative recruitment management solutions if the risk cannot be sufficiently mitigated until a patch is available. 8. Perform regular vulnerability scans and penetration tests focusing on web application components handling sensitive data to proactively identify similar issues.
