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 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 fresh worker UUID without any credentials. This grants the attacker 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 advisory is provided in the data, and no known exploits are reported in the wild.
AI Analysis
Technical Summary
The vulnerability CVE-2026-44592 affects wavelens gradient 1.1.0 when GRADIENT_DISCOVERABLE=true. It allows unauthenticated registration of workers via the /proto endpoint by submitting a new UUID, granting broad access (PeerAuth::Open) to jobs across organizations and the ability to inject arbitrary data into the storage backend. This is due to missing authentication for a critical function, categorized under CWE-306 (Missing Authentication for Critical Function), with related weaknesses 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.
Potential Impact
An attacker can gain unauthorized access to all jobs from every organization and can inject arbitrary data into the system's storage, potentially compromising the integrity and availability of the continuous integration environment. This could lead to unauthorized code execution or disruption of CI workflows. The vulnerability is critical with a CVSS score of 9.4, indicating severe impact if exploited.
Mitigation Recommendations
Upgrade wavelens gradient to version 1.1.1 or later where this vulnerability is fixed. Since no official patch link or advisory is provided, verify the update availability from the vendor or trusted sources. Until patched, restrict network access to the /proto endpoint to trusted users only to prevent unauthorized worker registration.
