A vulnerability, which was classified as problematic, has been found in KeyCloak up to 9.x. This issue affects an unknown part of the component NodeJS Adapter. The manipulation with an unknown input leads to a permissive list of allowed inputs vulnerability. Using CWE to declare the problem leads to CWE-183. The product implements a protection mechanism that relies on a list of inputs (or properties of inputs) that are explicitly allowed by policy because the inputs are assumed to be safe, but the list is too permissive - that is, it allows an input that is unsafe, leading to resultant weaknesses. Impacted is confidentiality. The summary by CVE is:
A flaw was found in all versions of Keycloak before 10.0.0, where the NodeJS adapter did not support the verify-token-audience. This flaw results in some users having access to sensitive information outside of their permissions.
