CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:HSummary
CVE-2026-35216 is a critical-severity OS Command Injection (CWE-78) vulnerability in Budibase Budibase. Its CVSS base score is 9.0 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 4% 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-2026-35216 is a remote code execution (RCE) vulnerability affecting Budibase, an open-source low-code platform, in versions prior to 3.33.4. The flaw stems from CWE-78 (OS Command Injection) and allows an unauthenticated attacker to execute arbitrary code on the Budibase server by triggering an automation workflow containing a Bash step through the public webhook endpoint. The vulnerability carries a CVSS v3.1 base score of 9.0 (AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H), reflecting its critical impact despite requiring high attack complexity.
Any unauthenticated remote attacker can exploit this vulnerability without privileges or user interaction by sending a crafted request to the public webhook endpoint, which triggers the malicious automation. Successful exploitation results in RCE on the server, with the Bash process executing as root within the container, potentially granting full control over the host environment, including data exfiltration, persistence, or further lateral movement.
Budibase has addressed the issue in version 3.33.4, as detailed in the official security advisory (GHSA-fcm4-4pj2-m5hf), release notes, associated pull request (#18238), and patching commit (f0c731b409a96e401445a6a6030d2994ff4ac256). Security practitioners should immediately upgrade to 3.33.4 or later and review webhook configurations to disable or restrict unauthenticated automations with Bash steps.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation can discover missing or incorrect command sanitization during development.
Input validation directly neutralizes or rejects special characters that would otherwise alter OS command structure.
Least privilege reduces the permissions available to any process that could be subverted by injected commands.
Least functionality restricts available OS commands and interpreters, limiting the blast radius of injection.
Secure engineering principles require proper neutralization of untrusted input before command construction.

PR.PS-06's SDLC practices directly require secure coding and input handling that blocks command-injection defects, yet the single broad outcome leaves many specific neutralization vectors and verification gaps unaddressed.
Routine patching/maintenance can remediate known command-injection CVEs in dependencies (partial forward) but does nothing to stop developers from introducing improper neutralization in custom code (none reverse).
