CVE-2026-48877Network attack vector

Authenticated sensitive-data disclosure via unfiltered REST response

Published May 27, 2026 · Updated May 27, 2026

Sensitive information exposure in GenerateBlocks 2.1.0 and earlier allows remote authenticated users to read sensitive values through its REST API. A REST API response serializes sensitive values to contributor-level callers instead of filtering fields by role. Contributor-level access is required, and the exposure is limited to data returned by the affected endpoint; no write or service interruption is reported.
