Summary
CVE-2026-25888 is a high-severity Code Injection (CWE-94) vulnerability in Depomo Chartbrew. Its CVSS base score is 8.8 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked in the top 39% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2026-25888 is a remote code execution vulnerability (classified under CWE-94) affecting Chartbrew, an open-source web application designed to connect directly to databases and APIs for creating data visualizations and charts. The flaw exists in a vulnerable API endpoint in versions prior to 4.8.1, allowing arbitrary code execution on the server hosting the application. It carries a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), indicating high severity due to its network accessibility and significant impacts.
An authenticated attacker with low privileges (PR:L), such as a registered user, can exploit this vulnerability remotely over the network with low complexity and no user interaction required. Successful exploitation grants high-level impacts on confidentiality, integrity, and availability, enabling the attacker to execute arbitrary code on the affected Chartbrew server, potentially leading to full system compromise, data exfiltration, or further lateral movement within the environment.
The issue has been addressed in Chartbrew version 4.8.1, as detailed in the project's release notes and security advisory. Security practitioners should upgrade to v4.8.1 or later, review access controls for API endpoints, and monitor for anomalous activity in affected deployments. Relevant resources include the GitHub release page at https://github.com/chartbrew/chartbrew/releases/tag/v4.8.1 and the security advisory at https://github.com/chartbrew/chartbrew/security/advisories/GHSA-875w-45c2-gxq8.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation finds code paths that accept and execute externally influenced strings.
Input validation directly stops untrusted data from being used to construct executable code without neutralization.
Least privilege limits the damage an injected code fragment can perform once executed.
Requiring documented secure development standards and tools enforces use of safe code-generation APIs and escaping.

PR.PS-06's SDLC practices directly target injection flaws via secure coding and testing (mostly), yet as a single broad outcome it leaves many code-generation specifics unaddressed (partial).

Banning unapproved code samples and unauthenticated web services, combined with secure-coding standards and SAST, prevents the dynamic generation or inclusion of attacker-supplied code.
