Curator notes
Pillar Security (Ariel Fogel). Reported 2026-08-03, patched 2026-08-04, CVE-2026-73554 / GHSA-mgpq-fxxc-h49q issued 2026-08-13, disclosed 2026-08-14. Ordinary web-auth bugs in MCP transports are an under-recorded category next to prompt injection; two independent defects composed into one unauthenticated request.
