CVE-2021-33190
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedIn Apache APISIX Dashboard version 2.6, we changed the default value of listen host to 0.0.0.0 in order to facilitate users to configure external network access. In the IP allowed list restriction, a risky function was used for the IP acquisition, which made it possible to bypass the network limit. At the same time, the default account and password are fixed.Ultimately these factors lead to the issue of security risks. This issue is fixed in APISIX Dashboard 2.6.1
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceApache APISIX Dashboard 2.6 listens on 0.0.0.0 by default, exposing the interface externally. A risky function used for IP acquisition in the allowed list restriction can be bypassed, allowing attackers to circumvent IP-based access controls. Combined with fixed default credentials, this enables unauthorized network access to the dashboard.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm installed Dashboard versionCheck the Apache APISIX Dashboard version running in your environment (e.g., via process info, package manager, or API endpoint /apisix/admin/widget/list)Affected if Version is exactly 2.6 (the only affected version listed)
-
Verify network binding configurationInspect the Dashboard configuration file (conf/conf.yaml or similar) and check the listen address under the manager_api sectionAffected if The listen address is set to 0.0.0.0, exposing the interface to all network interfaces rather than localhost only
-
Inspect IP restriction settingsCheck the allowed_list or ip_restriction configuration in the Dashboard API settings to see if IP-based access controls are definedAffected if An allowed_list is configured but relies on the bypassable IP acquisition function (the vulnerability exists when IP restrictions are in place)
-
Check for default credentialsTest authentication using the known fixed default credentials for the Dashboard (admin/admin is commonly documented)Affected if Default credentials are still active and allow successful authentication
You are affected if the Dashboard is version 2.6 AND it listens on 0.0.0.0 (exposed externally) AND either default credentials still work OR IP restrictions can be bypassed.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade to Apache APISIX Dashboard 2.6.1 or later and change default credentials to prevent exploitation of the IP restriction bypass.
