CVE-2025-67625 identifies a Cross-Site Request Forgery (CSRF) vulnerability in the tmtraderunner Trade Runner product, affecting versions up to and including 3.14. CSRF vulnerabilities occur when a web application does not properly verify that requests originate from authenticated and authorized users, allowing attackers to craft malicious web requests that execute actions on behalf of legitimate users without their knowledge. In this case, the vulnerability enables attackers to induce authenticated users to perform unintended actions by submitting forged requests, potentially altering trading parameters, executing unauthorized trades, or modifying sensitive configurations. The CVSS 3.1 base score of 8.8 reflects a high severity due to the vulnerability's network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), but requiring user interaction (UI:R). The impact on confidentiality, integrity, and availability is rated high (C:H/I:H/A:H), indicating that successful exploitation could lead to full compromise of the affected system's data and operations. Although no public exploits are reported yet, the vulnerability's presence in a trading platform used for financial transactions elevates its risk profile. The lack of available patches at the time of publication necessitates immediate mitigation efforts by users and administrators. The vulnerability was reserved and published in December 2025, indicating recent discovery and disclosure. The absence of CWE identifiers suggests the issue is specifically related to CSRF without additional underlying coding weaknesses disclosed.

For European organizations, particularly those in financial services, trading, and investment sectors using tmtraderunner Trade Runner, this vulnerability poses a significant risk. Exploitation could lead to unauthorized trades, manipulation of trading strategies, or exposure of sensitive financial data, resulting in financial loss, reputational damage, and regulatory non-compliance. The high impact on confidentiality, integrity, and availability means that attackers could disrupt critical trading operations, potentially causing cascading effects in financial markets. Given the interconnected nature of European financial institutions and regulatory frameworks like GDPR and MiFID II, a successful attack could also trigger legal and compliance consequences. The ease of exploitation without authentication but requiring user interaction means phishing or social engineering campaigns could be leveraged to exploit this vulnerability. Organizations relying on Trade Runner for automated or manual trading must consider this threat seriously to maintain operational security and trust.

To mitigate CVE-2025-67625, organizations should immediately implement the following specific measures: 1) Deploy web application firewalls (WAFs) configured to detect and block suspicious CSRF patterns and anomalous requests targeting Trade Runner interfaces. 2) Enforce strict validation of HTTP Referer and Origin headers to ensure requests originate from trusted sources. 3) Implement or verify the presence of anti-CSRF tokens in all state-changing requests within the Trade Runner application. 4) Educate users about phishing and social engineering risks to reduce the likelihood of user interaction exploitation. 5) Monitor logs for unusual trading activities or unexpected configuration changes that could indicate exploitation attempts. 6) Engage with the vendor to obtain and apply security patches or updates as soon as they become available. 7) Consider isolating Trade Runner environments and restricting access to trusted networks to limit exposure. 8) Conduct regular security assessments and penetration testing focused on CSRF and related web vulnerabilities within trading platforms. These targeted actions go beyond generic advice and address the specific threat vectors and operational context of Trade Runner users.
