CVE-2026-30232 — Chartbrew has SSRF in API Data Connection - No IP Validation on User-Provided URLs

Chartbrew is an open-source web application that can connect directly to databases and APIs and use the data to create charts. Prior to 4.8.5, Chartbrew allows authenticated users to create API data connections with arbitrary URLs. The server fetches these URLs using request-promise without any IP address validation, enabling Server-Side Request Forgery attacks against internal networks and cloud metadata endpoints. This vulnerability is fixed in 4.8.5.

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.
How the score was calculated
  • EPSS 0.4% (30-day exploitation probability)+5
  • Technical severity (critical)+10

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

  • Documented patch — github.com (NIST National Vulnerability Database)

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

  1. Identify exposed assets running the affected vendor/product/version combinations (Chartbrew Chartbrew, Depomo Chartbrew).
  2. Apply the fixed version or the patch documented under Remediation.
  3. Search available logs for exploit probes matching the vulnerability class (ssrf), errors and authentication anomalies.

What should defenders know first?

CVE-2026-30232 is "Chartbrew has SSRF in API Data Connection - No IP Validation on User-Provided URLs", rated Critical. It affects Chartbrew (Chartbrew); versions are in the scope table. It is not in CISA KEV, which does not rule out exploitation. CVSS 9.6 describes technical severity. EPSS 0.40% estimates the probability of exploitation in 30 days; neither replaces your asset context. First verify whether exposed or business-critical assets run the affected versions, apply vendor fixes or mitigations, and preserve logs for review.
