Summary
Budibase: Email Change IDOR via POST /api/v2/email allows full Account Takeover (accountId not validated against session)
Impact
An authenticated account-portal user who obtains a victim's accountId (out-of-band, it is not exposed anywhere in the normal cross-user API surface we could find) can take over that victim's account: rewrite the login email to an attacker address, set a new password, and access the victim's tenants, apps, and stored datasource credentials (REST/SQL/S3 auth). The victim is locked out of their own account. Every step from the initial IDOR write to full login-as-victim is deterministic and 100% reliable once the accountId is known, no additional vulnerability or guessing is required, since the chain uses nothing but the platform's own stock password-reset flow.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Validate that the body's accountId equals the authenticated session's accountId before starting or completing the email-change workflow (the same check already applied to currentEmail). Do not trust a client-supplied accountId to select the workflow target.
Frequently Asked Questions
- What is GHSA-C8VC-7PV3-G98P? GHSA-C8VC-7PV3-G98P is a high-severity security vulnerability in @budibase/server (npm), affecting versions <= 3.38.1. No fixed version is listed yet.
- Which versions of @budibase/server are affected by GHSA-C8VC-7PV3-G98P? @budibase/server (npm) versions <= 3.38.1 is affected.
- Is there a fix for GHSA-C8VC-7PV3-G98P? No fixed version is listed for GHSA-C8VC-7PV3-G98P yet. Monitor the advisory for updates and apply mitigations in the interim.
- Is GHSA-C8VC-7PV3-G98P exploitable, and should I be worried? Whether GHSA-C8VC-7PV3-G98P is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether GHSA-C8VC-7PV3-G98P is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
