OpenFUN Richie Observable Timing Discrepancy in its sync_course_run_from_request function

An issue in OpenFUN Richie LMS in src/richie/apps/courses/api.py. The application used the non-constant time == operator for HMAC signature verification in the synccourserunfromrequest function. This allows remote attackers to forge valid signatures and bypass authentication by measuring response...

GHSA-GQ3J-XVXP-8HRF Hono added timing comparison hardening in basicAuth and bearerAuth

Summary The basicAuth and bearerAuth middlewares previously used a comparison that was not fully timing-safe. The timingSafeEqual function used normal string equality === when comparing hash values. This comparison may stop early if values differ, which can theoretically cause small timing...
