MEDIUMPre-NVD 4.94.9—
EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 4.9 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.5%, top 61% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

Budibase is an open-source low-code platform. Prior to 3.39.25, GET /api/users/metadata and GET /api/users/metadata/:id returned user objects processed by packages/server/src/utilities/global.ts without removing oauth2.accessToken or oauth2.refreshToken. A user with the POWER role could retrieve the identity-provider credentials of SSO-authenticated users and use the refresh tokens for persistent access to connected services. This issue is fixed in version 3.39.25.
