Summary
CVE-2026-30232 is a high-severity SSRF (CWE-918) vulnerability in Depomo Chartbrew. Its CVSS base score is 7.8 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 33th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to AC-4 (Information Flow Enforcement) and SI-10 (Information Input Validation) — see the control section below for these in your framework.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2026-30232 is a Server-Side Request Forgery (SSRF) vulnerability, classified under CWE-918, affecting Chartbrew, an open-source web application that connects directly to databases and APIs to create charts. In versions prior to 4.8.5, Chartbrew allows authenticated users to create API data connections using arbitrary URLs, which the server fetches via the request-promise library without any IP address validation.
An attacker with low-privilege authenticated access to a Chartbrew instance can exploit this vulnerability remotely with low complexity and no user interaction required. By supplying a malicious URL, the attacker can force the server to make unauthorized requests to internal networks or cloud metadata endpoints, potentially compromising sensitive data. The CVSS v3.1 base score of 9.6 (AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:N) reflects the high confidentiality and integrity impacts with a changed scope.
The vulnerability is addressed in Chartbrew 4.8.5. Mitigation details are available in the GitHub security advisory at https://github.com/chartbrew/chartbrew/security/advisories/GHSA-p4rg-967r-w4cv and the fixing commit at https://github.com/chartbrew/chartbrew/commit/9c4a7e2b02acb25f0782bd4ac1f16407d59c2df1.

Mitigating Controls (NIST 800-53 r5) AI
Information flow enforcement can restrict which destinations the server is allowed to contact on behalf of users.
Input validation directly stops untrusted URLs from being accepted and fetched without destination checks.
Boundary protection limits the network reach of server-initiated requests even if SSRF occurs.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Secure development practices directly include input validation and destination allow-listing that prevent SSRF.
Runtime monitoring of web applications and services can detect anomalous outbound requests indicative of SSRF.
Vulnerability identification processes can discover and record SSRF flaws in web applications.
Network segmentation and egress controls can limit the damage from successful SSRF requests.
