CVE-2026-62314: CWE-284: Improper Access Control in TecharoHQ anubis
Anubis 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.
AI Analysis
Technical Summary
CVE-2026-62314 is an improper access control vulnerability (CWE-284) in TecharoHQ's Anubis firewall utility. The flaw exists in the PathChecker.Check() function within lib/policy/checker.go, which trusts the client-supplied X-Original-URI header over the actual r.URL.Path. This allows an attacker to bypass challenge mechanisms by matching default ALLOW rules such as ^/\.well-known/.*$, effectively circumventing protections against scraper bots. The vulnerability affects versions from 1.22.0 until 1.26.0-pre1 and is resolved in 1.26.0-pre1.
Potential Impact
An attacker can bypass the Anubis challenge mechanism, potentially allowing unauthorized access to protected upstream resources by exploiting the trust in the X-Original-URI header. The impact is limited to confidentiality as per the CVSS vector (C:L/I:N/A:N), with no integrity or availability impact reported.
Mitigation Recommendations
The issue is fixed in version 1.26.0-pre1. Users should upgrade to version 1.26.0-pre1 or later to remediate this vulnerability. Patch status is not explicitly confirmed beyond this fix version; check the vendor advisory for the latest remediation guidance.
