Use of Non-Canonical URL Paths for Authorization Decisions

As part of Cisco's ongoing commitment to proactive security and product quality, Cisco has conducted a comprehensive internal security review. This review resulted in a software hardening release that addresses multiple internally discovered vulnerabilities. The vulnerabilities tracked by CVE-2026-76530 are related to use of non-canonical URL paths for authorization decisions and are grouped under the Common Weakness Enumeration (CWE) CWE-647.Show less

Use of Non-Canonical URL paths for authorization decisions vulnerability in Apache APISIX. In some configurations where a permissive route overlaps a protected one, a crafted encoded path can reach an upstream endpoint that the matched route's policies were never meant to cover. A request that should have been rejected is served instead, giving unauthenticated access to a protected upstream endpoint. This issue affects Apache APISIX: from 2.14.1 through 3.18.0. Users are recommended to upgrade to version 3.19.0, which fixes the issue.Show less

Dell Secure Connect Gateway (SCG) Policy Manager, versions prior to 5.34.00.16, contains an Use of Non-Canonical URL Paths for Authorization Decisions vulnerability. An unauthenticated attacker with remote access could potentially exploit this vulnerability, leading to Unauthorized access.Show less

Envoy is an open source edge and service proxy designed for cloud-native applications. Prior to 1.36.10, 1.37.6, 1.38.4, and 1.39.1, Envoy's URL normalization does not recognize dot and dotdot path segments when they carry semicolon parameters. A request such as /user/..;foo=bar/admin is therefore not canonicalized to /admin even when path normalization is enabled. If an upstream interprets the segment according to RFC 3986 while Envoy applies routing or RBAC to the uncollapsed path, a remote client can cause path confusion and bypass path-based security policy. The relevant scope boundary is that the security consequence depends on a downstream/upstream path interpretation mismatch or a path-based Envoy decision. This issue is fixed in versions 1.36.10, 1.37.6, 1.38.4, and 1.39.1.Show less

In Eclipse Arrowhead versions from 5.0.0 to 5.2.1 the management-authorization gate that protects every /…/mgmt/… REST endpoint decides whether to apply its check by calling request.getRequestURL().toString().contains("/mgmt/"). Tomcat returns getRequestURL() un-decoded, while Spring MVC's DispatcherServlet routes on the decoded path. Requesting /serviceregistry/%6Dgmt/systems (%6D == m) therefore fails the substring check — the filter falls through without authorising — yet is decoded to /serviceregistry/mgmt/systems and dispatched to the management controller. Spring Security's StrictHttpFirewall (active via spring-boot-starter-security in arrowhead-common) only rejects encoded / \ . % ; and null bytes, so percent-encoded ASCII letters pass through. Any authenticated system — regardless of privilege — can reach every management operation, including POST /authentication/mgmt/identities which creates new sysop accounts, yielding full administrative takeover of the local cloud.Show less

Consul Community Edition and Consul Enterprise 1.20.1 through 2.0.2 are vulnerable to an L7 intention authorization bypass when a service proxy is configured with a custom public listener. An authenticated mesh workload may reach HTTP paths that are blocked by a path-based deny intention. This vulnerability, CVE-2026-15970, is fixed in Consul 2.0.3 and Consul Enterprise 1.21.17, 1.22.11, and 2.0.3.Show less

File Browser is a file managing interface for uploading, deleting, previewing, renaming, and editing files within a specified directory. Prior to 2.63.17, File Browser builds new user scopes from usernames passed through cleanUsername() when Signup=true and CreateUserDir=true, but the many-to-one normalization can collapse usernames such as team/one, team one, and team-one to the same home directory without checking whether the resulting scope is already taken, allowing a second registrant to gain full read and write access to another user's files. This issue is fixed in version 2.63.17.Show less

In Eclipse Jetty, an HTTP URI of this form: /public;/../admin/secret.txt results in an unresolved path of: /public/../admin/secret.txt instead of the expected: /admin/secret.txt Jetty itself is not affected, as it will not serve the secret.txt file because it will not pass the alias checker (only resolved resources are served). However, web applications that rely on resolved paths being provided by Jetty may be confused when receiving an unresolved path.Show less

Astro is a web framework for content-driven websites. Version 6.4.7 performs authorization decisions on a partially decoded pathname after reaching the iterative URL decoder limit, while later rewrite route matching performs an additional decodeURI() operation and can resolve the request to a protected route. This issue is fixed in version 6.4.8.Show less

Cargo between 1.68 and 1.96 incorrectly normalized the URLs of third-party registries using the sparse index protocol. If a hosting provider allowed multiple registries to be hosted with arbitrary names within the same domain, an attacker able to publish crates in a registry could obtain the credentials of others users of the same registry. The severity of the vulnerability is **low**, due to the extremely niche requirements needed to achieve the attack.Show less

A flaw was found in the Red Hat Ansible Automation Platform Gateway route creation component. This vulnerability allows credential theft via the creation of misleading routes using a double-slash (//) prefix in the gateway_path. A malicious or socially engineered administrator can configure a honey-pot route to intercept and exfiltrate user credentials, potentially maintaining persistent access or creating a backdoor even after their permissions are revoked.Show less

Astro is a web framework. Versions 5.15.7 and below have a double URL encoding bypass which allows any unauthenticated attacker to bypass path-based authentication checks in Astro middleware, granting unauthorized access to protected routes. While the original CVE-2025-64765 was fixed in v5.15.8, the fix is insufficient as it only decodes once. By using double-encoded URLs, attackers can still bypass authentication and access any route protected by middleware pathname checks. This issue is fixed in version 5.15.8.Show less

Symfony is a PHP framework for web and console applications and a set of reusable PHP components. Symfony's HttpFoundation component defines an object-oriented layer for the HTTP specification. Starting in version 2.0.0 and prior to version 5.4.50, 6.4.29, and 7.3.7, the `Request` class improperly interprets some `PATH_INFO` in a way that leads to representing some URLs with a path that doesn't start with a `/`. This can allow bypassing some access control rules that are built with this `/`-prefix assumption. Starting in versions 5.4.50, 6.4.29, and 7.3.7, the `Request` class now ensures that URL paths always start with a `/`.Show less

Sonos api.sonos.com through 2025-04-21, when the /login/v3/oauth endpoint is used, accepts a redirect_uri containing userinfo in the authority component, which is not consistent with RFC 6819 section 5.2.3.5. An authorization code may be sent to an attacker-controlled destination. This might have further implications in conjunction with "Decompiling the app revealed a hardcoded secret."Show less
