CVE-2026-62314
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 · uneditedAnubis is a Web AI Firewall Utility that challenges users' connections in order to protect upstream resources from scraper bots. From 1.22.0 until 1.26.0-pre1, lib/policy/checker.go PathChecker.Check() trusted the client-controlled X-Original-URI header before matching r.URL.Path, allowing an HTTP client to match default data/common/keep-internet-working.yaml ALLOW rules such as ^/\.well-known/.*$ and bypass the Anubis challenge. This issue is fixed in version 1.26.0-pre1.
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 confidenceIn Anubis Web AI Firewall versions 1.22.0 through 1.26.0-pre1, the PathChecker.Check() function in lib/policy/checker.go incorrectly trusted the client-supplied X-Original-URI header for path matching instead of using the server-controlled r.URL.Path. This allowed attackers to send malicious X-Original-URI values matching ALLOW rules like ^/\.well-known/.*$ to bypass the challenge mechanism.

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.
-
Check Anubis Web AI Firewall versionRun 'anubisctl version' or inspect the binary/version file to determine the installed version numberAffected if The installed version is 1.22.0, 1.23.x, 1.24.x, 1.25.x, or 1.26.0-pre1 (any version from 1.22.0 through 1.26.0-pre1)
-
Identify PathChecker policy rulesExamine the Anubis policy configuration files (typically in /etc/anubis/policy/ or the configured policy directory) and search for PathChecker definitions in lib/policy/checker.go or equivalent policy filesAffected if PathChecker is configured with ALLOW rules that use regex patterns (such as ^/\.well-known/.*$) for path matching
-
Verify X-Original-URI header processingInspect the Anubis configuration or HTTP request logs to determine if the X-Original-URI header is being read and passed to PathChecker.Check()Affected if X-Original-URI header handling is enabled and PathChecker uses it for path validation instead of r.URL.Path alone
-
Test for bypass vulnerabilitySend a request with X-Original-URI: /.well-known/anything to an endpoint that should be blocked, and observe if the request bypasses the challenge mechanism due to the header being matched against ALLOW rulesAffected if Requests with malicious X-Original-URI values successfully bypass ALLOW rules that should block them
You are affected if Anubis Web AI Firewall version is between 1.22.0 and 1.26.0-pre1, PathChecker is using ALLOW rules with regex patterns, and X-Original-URI header processing is enabled, allowing client-supplied headers to bypass path-based access controls.
Generated from the published advisory. Verify against your own configuration.
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.
dbcve · scopedUpgrade to Anubis version 1.26.0-pre1 or later. As a defense-in-depth measure, ensure policy matching uses only server-controlled path variables (r.URL.Path) rather than client-supplied headers.
1.26.0-pre1
- 1. Identify the current version of Anubis being used by checking the binary or configuration
- 2. If the version is between 1.22.0 and 1.26.0-pre1 (inclusive), upgrade to version 1.26.0-pre1 or later
- 3. Verify the upgrade was successful by checking the new version number
