CVE-2025-54748 is a path traversal vulnerability identified in the RomanCode MapSVG plugin, a tool used to create interactive vector maps on websites. The vulnerability arises due to improper limitation of pathname inputs, allowing attackers to manipulate file paths and access files outside the intended restricted directories. This can lead to unauthorized reading of sensitive files on the server, such as configuration files, credentials, or other critical data. The affected versions include all releases prior to 8.6.12, with no specific initial version identified. The vulnerability does not require authentication, increasing its risk profile, and does not require user interaction, making automated exploitation feasible. Although no known exploits have been reported in the wild, the flaw's nature suggests that attackers could craft HTTP requests to exploit the path traversal. The lack of a CVSS score indicates the need for an independent severity assessment. The vulnerability impacts the confidentiality and potentially the integrity of data hosted on affected systems. Since MapSVG is a popular plugin for WordPress and other CMS platforms, the attack surface includes many websites that utilize interactive maps. The issue was reserved in July 2025 and published in December 2025, indicating recent discovery and disclosure. No official patches or mitigation links were provided at the time of reporting, emphasizing the need for vigilance and proactive defense measures.

For European organizations, the primary impact is unauthorized disclosure of sensitive information stored on web servers running vulnerable versions of MapSVG. This could include internal configuration files, user data, or proprietary information, leading to data breaches and regulatory compliance violations under GDPR. The exposure of sensitive files can facilitate further attacks, such as privilege escalation or lateral movement within networks. Organizations relying on MapSVG for customer-facing or internal applications risk reputational damage and operational disruption if exploited. The vulnerability's ease of exploitation without authentication increases the likelihood of automated scanning and attacks. Additionally, organizations in sectors with high data sensitivity, such as finance, healthcare, and government, face elevated risks. The absence of known exploits currently provides a window for remediation, but also suggests attackers may develop exploits soon. Overall, the threat undermines confidentiality and could indirectly affect integrity and availability if attackers leverage disclosed information for further compromise.

1. Immediately upgrade the MapSVG plugin to version 8.6.12 or later once the patch is officially released by RomanCode. 2. Until a patch is available, implement strict input validation on all parameters that accept file paths or user-supplied data to prevent directory traversal sequences (e.g., ../). 3. Configure web server access controls to restrict access to sensitive directories and files, using mechanisms such as .htaccess rules or web application firewalls (WAFs). 4. Employ WAF rules specifically targeting path traversal attack patterns to detect and block malicious requests. 5. Conduct thorough security audits of web applications using MapSVG to identify any exposure of sensitive files. 6. Monitor web server logs for unusual access patterns indicative of path traversal attempts. 7. Educate development and operations teams about secure coding practices related to file path handling. 8. Consider isolating the web application environment to limit the impact of potential breaches. 9. Maintain regular backups and incident response plans to quickly recover from any exploitation. 10. Engage with RomanCode support or security advisories for updates and guidance.
