This vulnerability (CVE-2026-48836) in MantraBrain Easy Invoice (<= 2.1.19) is classified as CWE-94, indicating improper control of code generation leading to code injection. It allows unauthenticated remote attackers to execute arbitrary code on the affected system, resulting in full compromise (confidentiality, integrity, and availability impact). The CVSS 3.1 vector indicates network attack vector, low attack complexity, no privileges or user interaction required, and scope change with high impact on confidentiality, integrity, and availability. No patch or official remediation level has been disclosed by the vendor or authoritative sources as of the publication date.

Successful exploitation results in unauthenticated remote code execution, allowing attackers to fully compromise the affected system, including complete loss of confidentiality, integrity, and availability. This can lead to unauthorized control over the Easy Invoice application and potentially the underlying host system.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict network access to the Easy Invoice application and monitor for suspicious activity. Avoid exposing the application to untrusted networks.
