CVE-2025-69055 is a path traversal vulnerability identified in SeaTheme's BM Content Builder, a content management tool used for building and managing digital content. The vulnerability arises due to improper limitation of pathnames to restricted directories, allowing an attacker with limited privileges to traverse directories and access files outside the intended scope. This can be exploited remotely over the network (AV:N) without user interaction (UI:N), but requires some level of privileges (PR:L), indicating that the attacker must have authenticated access with limited rights. The vulnerability affects all versions up to and including 3.16.3. Successful exploitation can lead to unauthorized disclosure of sensitive files, impacting confidentiality, but does not compromise data integrity or system availability. Although no public exploits are known at this time, the medium CVSS score of 6.5 reflects the significant risk posed by unauthorized data access. The vulnerability was reserved at the end of 2025 and published in early 2026, indicating recent discovery and disclosure. The lack of available patches or mitigation links suggests that organizations should proactively implement compensating controls until official patches are released.

For European organizations, the primary impact is unauthorized disclosure of sensitive information due to path traversal, which can lead to data breaches, compliance violations (e.g., GDPR), and reputational damage. Since the vulnerability requires some level of authenticated access, insider threats or compromised accounts could be leveraged to exploit this flaw. Organizations relying on BM Content Builder for managing critical or sensitive content are at risk of exposing confidential files to unauthorized users. This could affect sectors such as government, finance, healthcare, and media, where content confidentiality is paramount. The lack of impact on integrity and availability reduces the risk of system disruption but does not diminish the seriousness of potential data leaks. The absence of known exploits currently provides a window for mitigation, but the vulnerability could be targeted in the future as awareness grows.

1. Immediately audit and restrict user privileges within BM Content Builder to the minimum necessary, reducing the risk of exploitation by limited-privilege users. 2. Implement strict input validation and sanitization on all file path inputs to prevent directory traversal sequences (e.g., '..\' or '../'). 3. Employ web application firewalls (WAFs) with rules designed to detect and block path traversal attempts targeting BM Content Builder endpoints. 4. Monitor logs for unusual file access patterns or unauthorized attempts to access restricted directories. 5. Segregate sensitive files and directories with additional access controls outside the application’s reach. 6. Engage with SeaTheme for timely updates and patches; prioritize patch deployment once available. 7. Consider temporary disabling or limiting access to BM Content Builder modules that handle file paths until patches are applied. 8. Conduct security awareness training for administrators and users to recognize and report suspicious activities related to content management systems.
