CVE-2026-11922

A vulnerability in zenml-io/zenml versions 0.57.0 through 0.94.2 allows an attacker to bypass rate-limiting on the POST /api/v1/login and self password-change endpoints by rotating the X-Forwarded-For header. The rate limiter keys requests by request.client.host, which is derived from the...

CVE-2026-11922 Rate-limit Bypass in zenml-io/zenml

A vulnerability in zenml-io/zenml versions 0.57.0 through 0.94.2 allows an attacker to bypass rate-limiting on the POST /api/v1/login and self password-change endpoints by rotating the X-Forwarded-For header. The rate limiter keys requests by request.client.host, which is derived from the...

CVE-2026-11922

The CVE-2026-11922 entry describes a rate-limit bypass in zenml-io/zenml (versions 0.57.0–0.94.2). The issue arises because the rate limiter uses request.client.host (derived from the X-Forwarded-For header when Uvicorn is run with --proxy-headers --forwarded-allow-ips *), allowing an attacker to...
