CVE-2025-62062 is a vulnerability identified in the ThemeRuby Easy Post Submission plugin, specifically affecting versions up to and including 1.7.0. The flaw allows an attacker to insert sensitive information into data sent by the plugin, enabling retrieval of embedded sensitive data without requiring any authentication or user interaction. The vulnerability is remotely exploitable over the network (AV:N) with low attack complexity (AC:L), and it does not require privileges (PR:N) or user interaction (UI:N). The impact is limited to confidentiality loss (C:L) without affecting integrity (I:N) or availability (A:N), resulting in a CVSS v3.1 base score of 5.3, categorized as medium severity. The vulnerability arises from improper handling or sanitization of data within the plugin’s submission process, which can be manipulated to expose sensitive information embedded in the sent data payloads. No known exploits have been reported in the wild, and no patches have been officially released at the time of publication. The plugin is commonly used in WordPress environments to facilitate post submissions, making websites that rely on it potentially vulnerable to data leakage. The vulnerability could be leveraged by attackers to harvest sensitive information such as tokens, credentials, or personal data embedded in submission forms or payloads, potentially aiding further attacks or privacy breaches.

For European organizations, the primary impact of CVE-2025-62062 is the unauthorized disclosure of sensitive information, which could include personal data, authentication tokens, or other confidential content embedded in post submissions. This exposure can lead to privacy violations under GDPR, reputational damage, and potential compliance penalties. Although the vulnerability does not directly affect system integrity or availability, the leaked information could be used in subsequent targeted attacks such as phishing, account takeover, or lateral movement within networks. Organizations relying on the Easy Post Submission plugin for customer interactions, content management, or data collection are at risk. The impact is particularly significant for sectors handling sensitive personal or financial data, such as finance, healthcare, and e-commerce. Since exploitation requires no authentication or user interaction, attackers can remotely and stealthily extract data, increasing the risk of widespread data leakage if the plugin is widely deployed without mitigation.

1. Immediately audit all instances of the ThemeRuby Easy Post Submission plugin in your environment to identify affected versions (<=1.7.0). 2. Monitor ThemeRuby’s official channels and trusted vulnerability databases for patches or updates addressing CVE-2025-62062 and apply them promptly once available. 3. Until patches are released, consider disabling or removing the plugin if it is not critical to operations. 4. Review and minimize the amount of sensitive data embedded or transmitted via the plugin’s submission forms to reduce exposure. 5. Implement strict input validation and output sanitization on all data handled by the plugin to prevent unauthorized data insertion or leakage. 6. Deploy Web Application Firewalls (WAFs) with custom rules to detect and block anomalous data patterns indicative of exploitation attempts targeting this vulnerability. 7. Conduct regular security assessments and penetration testing focusing on web application data flows involving the plugin. 8. Educate development and content teams about secure data handling practices related to post submission features. 9. Maintain comprehensive logging and monitoring to detect unusual data access or exfiltration activities associated with the plugin.
