CVE-2026-7784
Published: 05 May 2026
Summary
CVE-2026-7784 is a medium-severity Path Traversal (CWE-22) vulnerability. Its CVSS base score is 5.5 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 7.6th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and AC-3 (Access Enforcement).
Deeper analysis
CVE-2026-7784 is a path traversal vulnerability (CWE-22) affecting RTGS2017 NagaAgent versions up to 5.1.0. The issue resides in the processing of the file apiserver/routes/extensions.py within the Skills Endpoint component, where manipulation of the "Name" argument enables traversal outside intended directories. Assigned a CVSS v3.1 base score of 7.3 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L), it was published on 2026-05-05.
Remote attackers require only network access to exploit this vulnerability, with no privileges, user interaction, or special conditions needed due to its low attack complexity. Successful exploitation allows limited impacts on confidentiality, integrity, and availability, potentially enabling unauthorized file reads, modifications, or disruptions within the affected agent's scope.
Advisories from VulDB and the project's GitHub repository indicate the vulnerability was reported early via issue #311, but the maintainers have not responded or issued patches as of the latest information. The exploit has been publicly disclosed and may be actively used by attackers.
Notable context includes the lack of vendor response, increasing risk for deployments of NagaAgent up to 5.1.0, with the GitHub repository serving as a primary reference for potential monitoring or manual fixes.

Why these techniques?
Path traversal in unauthenticated network-accessible Skills Endpoint directly enables T1190 (exploit of public-facing app) and facilitates T1005 (arbitrary local file reads/modifications).

Mitigating Controls (NIST 800-53 r5) AI
Directly blocks manipulation of the Name argument in the Skills Endpoint by validating inputs to reject path traversal sequences such as ../ before they reach apiserver/routes/extensions.py.
Enforces access control policy on file resources so that even a successful traversal attempt cannot read or modify files outside the intended directory scope.
Monitors for anomalous file-access patterns or directory traversal strings in requests to the exposed Skills Endpoint, enabling detection of exploitation attempts against unpatched NagaAgent instances.
