CVE-2025-65944Network attack vector

Credential disclosure via unredacted trace span headers

Published Nov 25, 2025 · Updated Nov 25, 2025

Sensitive-data exposure in Sentry JavaScript SDK 10.11.0 through 10.26.0 allows remote authenticated users to obtain HTTP credentials. The httpHeadersToSpanAttributes function adds incoming headers to trace span attributes, while shared SDK and Relay matching logic fails to redact Authorization and Cookie values when sendDefaultPii is true. Access to the application's Sentry organization is required; exposed cookies or tokens enable impersonation or privilege escalation within the instrumented application.
