CVE-2026-11500 Details
Description
A vulnerability was identified in Weaviate up to 1.37.7. This vulnerability affects the function validateConfig of the file usecases/auth/authentication/apikey/client.go of the component Static API Key Handler. The manipulation of the argument StaticApiKey leads to authorization bypass. It is possible to initiate the attack remotely. The complexity of an attack is rather high. It is stated that the exploitability is difficult. The exploit is publicly available and might be used. Upgrading to version 1.38.0-rc.0 is able to resolve this issue. The identifier of the patch is 40f2cc32279f0f8a51016c3c6870a2c0c808e6c0. You should upgrade the affected component.
An authorization bypass vulnerability has been identified in Weaviate versions prior to 1.37.7. The issue arises in the Static API Key Handler component, specifically within the validateConfig function of the file usecases/auth/authentication/apikey/client.go. The vulnerability allows for duplicate static API keys to be configured for different users, leading to privilege confusion. When the same key is assigned to multiple users, Weaviate authenticates based on the first matching entry, potentially granting unauthorized access to admin privileges. This vulnerability can be exploited remotely, although the attack complexity is considered high.
Upgrade to Weaviate version 1.38.0-rc.0 or later, where this vulnerability has been addressed.
