CVE-2025-13129 identifies a vulnerability in the Onaylarım product developed by Seneka Software Hardware Information Technology Trade Contracting and Industry Ltd. Co. The issue is classified under CWE-841, which refers to improper enforcement of behavioral workflow. This means that the software does not adequately enforce the intended sequence or conditions under which certain functions or operations should be performed, allowing an attacker or a malicious insider to misuse functionality beyond its intended scope. The affected versions include 25.09.26.01 through 18112025, with the vulnerability published on December 1, 2025. The CVSS v3.1 base score is 3.5, indicating a low severity level. The vector string (AV:N/AC:L/PR:L/UI:R/S:U/C:N/I:L/A:N) shows that the attack can be performed remotely over the network with low complexity, requires privileges, and user interaction, and impacts only integrity without affecting confidentiality or availability. No patches or known exploits are currently available. The vulnerability could allow an attacker with some level of access to manipulate workflows or processes in Onaylarım, potentially leading to unauthorized actions or data manipulation within the system's operational context. This could affect business processes relying on Onaylarım for contract approvals or industry-related workflows, causing operational inconsistencies or errors.

For European organizations using Onaylarım, the impact is primarily on the integrity of business workflows and processes. Since the vulnerability allows functionality misuse, attackers or insiders might bypass intended controls or perform unauthorized actions within the software, potentially leading to incorrect contract approvals or industrial process errors. Although confidentiality and availability are not directly impacted, the integrity issues could result in financial discrepancies, compliance violations, or reputational damage. The requirement for privileges and user interaction limits the ease of exploitation but does not eliminate risk, especially in environments with multiple users or complex workflows. Organizations in sectors relying heavily on contract management and industrial process software could face operational disruptions or audit challenges if this vulnerability is exploited. The absence of known exploits reduces immediate risk but does not preclude future attacks once exploit code becomes available.

1. Conduct a thorough review of user privileges and restrict access to Onaylarım functions to the minimum necessary for each role. 2. Implement strict workflow validation and monitoring to detect deviations or misuse of functionality in real-time. 3. Train users on the risks of improper workflow actions and the importance of following established procedures to reduce the chance of accidental misuse. 4. Monitor vendor communications closely for patches or updates addressing this vulnerability and apply them promptly once available. 5. Employ network segmentation and access controls to limit exposure of Onaylarım to only trusted users and systems. 6. Use logging and audit trails to track workflow actions and investigate anomalies quickly. 7. Consider deploying application-layer security controls or behavioral analytics to detect unusual workflow patterns indicative of exploitation attempts.
