CVE-2025-59002 is a high-severity vulnerability classified under CWE-22, which pertains to improper limitation of a pathname to a restricted directory, commonly known as a Path Traversal vulnerability. This vulnerability affects the SeaTheme BM Content Builder product. Path Traversal vulnerabilities allow an attacker to manipulate file paths in such a way that they can access files and directories outside the intended restricted directory. In this case, the vulnerability allows an attacker with network access and low privileges (PR:L) to exploit the flaw without requiring user interaction (UI:N). The CVSS 3.1 score of 7.7 reflects a high severity, primarily due to the potential impact on availability (A:H) with no direct impact on confidentiality or integrity. The scope is changed (S:C), indicating that the vulnerability can affect resources beyond the initially vulnerable component. Although the vulnerability does not directly compromise confidentiality or integrity, the high impact on availability suggests that an attacker could cause denial of service or disrupt the normal operation of the BM Content Builder by accessing or manipulating critical files outside the intended directory. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability was published on September 26, 2025, with a reservation date of September 6, 2025. The lack of specified affected versions (noted as 'n/a') suggests that the vulnerability may affect multiple or all versions of the BM Content Builder, or that version details are not yet disclosed. Overall, this vulnerability poses a significant risk to organizations using SeaTheme BM Content Builder, especially those exposing the product to external networks, as it can lead to service disruption and potential further exploitation if combined with other vulnerabilities.

For European organizations using SeaTheme BM Content Builder, this vulnerability could lead to significant operational disruptions. The ability to perform path traversal attacks remotely with low privileges and no user interaction means attackers could potentially disrupt content management workflows, cause denial of service, or manipulate system files critical to the application’s availability. This could affect websites, intranet portals, or digital content platforms relying on BM Content Builder, leading to downtime and loss of service continuity. While confidentiality and integrity impacts are not directly indicated, availability issues can indirectly affect business operations and reputation. Additionally, if attackers leverage this vulnerability as a foothold, they might chain it with other exploits to escalate privileges or exfiltrate data. European organizations in sectors such as media, publishing, education, and government that rely on SeaTheme BM Content Builder for content management are particularly at risk. The disruption could also affect compliance with European regulations like GDPR if service outages impact data processing or availability guarantees.

1. Immediate isolation of BM Content Builder instances from public or untrusted networks until a patch or fix is available. 2. Implement strict input validation and sanitization on all file path inputs to prevent traversal sequences (e.g., '../'). 3. Employ web application firewalls (WAFs) with custom rules to detect and block path traversal attempts targeting BM Content Builder endpoints. 4. Restrict file system permissions for the BM Content Builder process to the minimum necessary, ensuring it cannot access critical system directories or files outside its designated content directories. 5. Monitor logs for unusual file access patterns or errors indicative of path traversal attempts. 6. Engage with SeaTheme support or vendor channels to obtain patches or updates as soon as they are released. 7. Conduct internal security assessments and penetration tests focusing on path traversal vectors within BM Content Builder deployments. 8. If possible, deploy the application within containerized or sandboxed environments to limit the blast radius of potential exploitation. 9. Maintain up-to-date backups of content and configurations to enable rapid recovery in case of service disruption.
