CVE-2026-44592: CWE-306: Missing Authentication for Critical Function in wavelens gradient
CVE-2026-44592 is a critical vulnerability in wavelens gradient version 1. 1. 0, a nix-based continuous integration system. When the configuration variable GRADIENT_DISCOVERABLE is set to true (the default), an unauthenticated attacker who can access the /proto endpoint can register as a worker by submitting a new worker UUID without any credentials. This grants the attacker a session with PeerAuth::Open privileges, allowing visibility into jobs from all organizations and the ability to push arbitrary store paths into the system's nar_storage and cached_path tables. This vulnerability is fixed in version 1. 1. 1. No official patch link or vendor advisory is provided in the data, and the remediation level is not specified.
AI Analysis
Technical Summary
The vulnerability arises from missing authentication controls on the /proto endpoint in wavelens gradient 1.1.0 when GRADIENT_DISCOVERABLE=true. Attackers can register as workers without credentials, gaining broad access to job data across organizations and the ability to inject arbitrary data into the storage backend. This is classified under CWE-306 (Missing Authentication for Critical Function), CWE-345, and CWE-862. The CVSS 3.1 score is 9.4 (critical), reflecting network attack vector, no privileges required, no user interaction, and high impact on integrity and availability. The issue is resolved in version 1.1.1, though no direct patch link or detailed vendor advisory is available.
Potential Impact
An unauthenticated attacker can register as a worker and gain access to jobs from all organizations using the gradient system. The attacker can also inject arbitrary store paths into the nar_storage and cached_path tables, potentially compromising the integrity and availability of the system. The CVSS score of 9.4 indicates a critical impact with high integrity and availability consequences.
Mitigation Recommendations
Upgrade to wavelens gradient version 1.1.1 or later, where this vulnerability is fixed. Since no official patch link or advisory is provided, verify the upgrade from the vendor's official sources. Until upgraded, consider disabling or restricting access to the /proto endpoint or setting GRADIENT_DISCOVERABLE to false if feasible to prevent unauthorized worker registration.
