ZenML ZenML Server - Improper Authentication

ZenML Server in the ZenML machine learning package before 0.46.7 for Python allows remote privilege escalation because the /api/v1/users/usernameorid/activate REST API endpoint allows access on the basis of a valid username along with a new password in the request body. id: CVE-2024-25723 info:...

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

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...

PYSEC-2026-2071 ZenML is vulnerable to Path Traversal through its `PathMaterializer` class

ZenML version 0.83.1 is affected by a path traversal vulnerability in the PathMaterializer class. The load function uses ispathwithindirectory to validate files during data.tar.gz extraction, which fails to effectively detect symbolic and hard links. This vulnerability can lead to arbitrary file...

PYSEC-2026-2070 Missing ratelimit on passwrod resets in zenml

zenml-io/zenml version 0.56.4 is vulnerable to an account takeover due to the lack of rate-limiting in the password change function. An attacker can brute-force the current password in the 'Update Password' function, allowing them to take over the user's account. This vulnerability is due to the...

PYSEC-2026-2068 Improper line feed handling in zenml

A denial of service DoS vulnerability exists in zenml-io/zenml version 0.56.3 due to improper handling of line feed \n characters in component names. When a low-privileged user adds a component through the API endpoint api/v1/workspaces/default/components with a name containing a \n character, it...

PYSEC-2026-2069 zenml-io/zenml does not expire the session after password reset

A vulnerability in zenml-io/zenml version 0.56.3 allows attackers to reuse old session credentials or session IDs due to insufficient session expiration. Specifically, the session does not expire after a password change, enabling an attacker to maintain access to a compromised account without the...
