CVE-2025-62139 is a vulnerability identified in the Vladimir Statsenko Terms descriptions product, affecting versions up to 3.4.9. It is categorized under CWE-201, which pertains to the insertion of sensitive information into sent data, enabling attackers to retrieve embedded sensitive data unintentionally exposed by the application. The vulnerability allows remote attackers to access sensitive information without requiring any privileges or user interaction, as indicated by the CVSS vector (AV:N/AC:L/PR:N/UI:N). The flaw does not affect data integrity or availability but compromises confidentiality by leaking sensitive information embedded in transmitted data. The attack complexity is low, meaning exploitation does not require specialized conditions or knowledge. Although no known exploits are currently in the wild and no patches have been published, the vulnerability poses a risk of data leakage, which could lead to further targeted attacks or compliance violations. The lack of patch availability necessitates proactive mitigation strategies. The vulnerability's presence in a product used for managing or describing terms suggests that sensitive contractual or policy information could be exposed, potentially impacting organizations relying on this software for legal or operational documentation. The vulnerability was reserved in October 2025 and published at the end of 2025, indicating a recent discovery and disclosure timeline.

For European organizations, the primary impact of CVE-2025-62139 is the unauthorized disclosure of sensitive information, which can lead to confidentiality breaches. This may include exposure of proprietary business terms, contractual details, or personal data embedded within the Terms descriptions product. Such data leakage can result in reputational damage, regulatory penalties under GDPR, and increased risk of targeted phishing or social engineering attacks. Since the vulnerability does not affect integrity or availability, operational disruption is unlikely; however, the confidentiality compromise alone can have significant legal and financial consequences. Organizations in sectors handling sensitive contracts, legal documentation, or personal data are particularly vulnerable. The remote and unauthenticated nature of the exploit increases the risk of widespread scanning and exploitation attempts, especially if the product is exposed to the internet or accessible within corporate networks. The absence of known exploits currently reduces immediate risk but does not eliminate the potential for future attacks once exploit code becomes available.

1. Immediately inventory and identify all instances of Vladimir Statsenko Terms descriptions deployed within the organization, focusing on versions up to 3.4.9. 2. Restrict network access to the affected product by implementing firewall rules or network segmentation to limit exposure to trusted internal networks only. 3. Monitor network traffic for unusual data transmissions that may indicate sensitive information leakage. 4. Conduct thorough audits of the data embedded within Terms descriptions to minimize the inclusion of sensitive information where possible. 5. Engage with the vendor or community to obtain updates or patches as soon as they become available and plan for prompt deployment. 6. Implement data loss prevention (DLP) solutions to detect and block unauthorized transmission of sensitive data. 7. Educate relevant staff about the risks associated with this vulnerability and encourage vigilance for suspicious activity. 8. Consider temporary mitigation by disabling or limiting the functionality of the Terms descriptions product if feasible until a patch is released. 9. Review and update incident response plans to include scenarios involving data leakage from this vulnerability. 10. Maintain up-to-date backups and logs to support forensic analysis in case of exploitation.
