CVE-2026-62314: CWE-284: Improper Access Control in TecharoHQ anubis
Anubis, a Web AI Firewall Utility by TecharoHQ, contains an improper access control vulnerability in versions from 1.22.0 up to but not including 1.26.0-pre1. The vulnerability arises because the PathChecker.Check() function trusts the client-controlled X-Original-URI header before matching the actual request URL path. This allows an attacker to bypass the Anubis challenge by matching certain ALLOW rules, such as those for /.well-known/ paths. The issue is fixed starting with version 1.26.0-pre1.
AI Analysis
Technical Summary
CVE-2026-62314 is an improper access control vulnerability (CWE-284) in TecharoHQ's Anubis Web AI Firewall Utility. Specifically, in versions 1.22.0 through 1.26.0-pre1, the PathChecker.Check() function in lib/policy/checker.go incorrectly trusts the client-supplied X-Original-URI HTTP header before matching the request URL path (r.URL.Path). This flaw allows an attacker to bypass the Anubis challenge mechanism by exploiting default ALLOW rules such as ^/\.well-known/.*$, effectively circumventing protections against scraper bots. The vulnerability is resolved in version 1.26.0-pre1.
Potential Impact
An attacker can bypass the Anubis challenge that is designed to protect upstream resources from scraper bots by manipulating the X-Original-URI header. This leads to unauthorized access to resources that would normally be challenged, potentially exposing protected endpoints matching default ALLOW rules. The CVSS v3.1 base score is 5.8 (medium severity), reflecting network attack vector, low attack complexity, no privileges or user interaction required, scope change, and limited confidentiality impact.
Mitigation Recommendations
The vulnerability is fixed in Anubis version 1.26.0-pre1. Users should upgrade to version 1.26.0-pre1 or later to remediate this issue. Patch status is not explicitly confirmed beyond this fix version; therefore, verify with the vendor for any additional remediation guidance or updates.
