CVE-2026-114261 MomoTommy CVE debrief

Who should care

Defenders responsible for systems using the MomoTommy file-management-system should assess exposure to this vulnerability and prioritize verification and mitigation efforts. This includes operators, platform administrators, vulnerability management teams, and security teams who need to verify the presence of the vulnerable component in their systems, assess exposure to the vulnerability, and implement compensating controls to mitigate the vulnerability.

Why it matters

Defenders should prioritize verifying the presence of this vulnerability in their systems and assessing exposure, as the exploit is publicly available and can be launched remotely. The vulnerability allows remote exploitation due to missing authentication in the Files API, and its presence in the system could lead to unauthorized access.

• Remote exploitation of the vulnerability is possible
• Public exploit is available, increasing the risk of exploitation
• Missing authentication in the Files API allows unauthorized access
• Verification of system exposure and vulnerability presence is necessary

Technical summary

The vulnerability is located in the FileController.php component of the Files API in the MomoTommy file-management-system. The issue arises from missing authentication in the index/store/update/destroy functions, allowing for remote exploitation. This vulnerability can be exploited remotely, and a public exploit has been made available. However, due to the lack of versioning in the product, information about affected and unaffected releases is unavailable. Defenders should prioritize verifying the presence of this vulnerability in their systems and assessing exposure, as the exploit is publicly available and can be launched remotely.

Defensive priority

Defenders should prioritize verifying the presence of this vulnerability in their systems and assessing exposure, as the exploit is publicly available and can be launched remotely.

Recommended defensive actions

• Verify the presence of the vulnerable component in your system
• Assess exposure to the vulnerability
• Implement compensating controls to mitigate the vulnerability
• Monitor for potential exploitation attempts
• Review relevant logs for exposed assets that need extra review
• Track exceptions and retest remediated assets
• Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed

Evidence notes

The CVE record and NVD entry provide details about the vulnerability, including its description, CVSS score, and affected components. However, the product does not use versioning, making it difficult to determine affected and unaffected releases.
