Base vector

AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N

Name of the Vulnerable Software and Affected Versions Chat Server versions 2.3.2 through 2.5.x

Description The issue concerns a bug in validating the access token, resulting in authentication bypass. The function this.authProvider.verifyAccessKey is an async function, but the code does not use await to wait for the verification result, causing the function to respond with success along with an unhandled exception if the token is invalid.

Recommendations For versions 2.3.2 through 2.5.x, update to version 2.6.0 to resolve the issue. As a temporary workaround, consider modifying the this.authProvider.verifyAccessKey function to properly handle the async verification result until a patch is applied.
