Credential theft via sensitive business-log telemetry
Published Sep 2, 2026 · Updated Sep 2, 2026
Sensitive data exposure in Boruta before 0.10.0 allows attackers with log access to recover OAuth and OpenID Connect credentials. Successful authorization, token, direct-post, introspection, and revocation telemetry passes bearer artifacts into BorutaWeb.Logger, which writes them as business-log attributes. Access to application logs, an aggregation system, or the administration log viewer is required; valid tokens grant access permitted by their scopes until expiration or revocation.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
