Allowed

Permissive Cross-domain Security Policy with Untrusted Domains

Title
AnythingLLM Permissable CORS policy
Summary
AnythingLLM is an application that turns pieces of content into context that any LLM can use as references during chatting. In 1.11.1 and earlier, On default installations where no password or API key has been configured, all HTTP endpoints and the agent WebSocket lack authentication, and the server's CORS policy accepts any origin. AnythingLLM Desktop binds to 127.0.0.1 (loopback) by default. Modern browsers (Chrome, Edge, Firefox) implement Private Network Access (PNA). This explicitly blocks public websites from making requests to local IP addresses. Exploitation is only viable from within the same local network (LAN) due to browser-level blocking of public-to-private requests.

Title
Glances's Default CORS Configuration Allows Cross-Origin Credential Theft
Summary
Glances is an open-source system cross-platform monitoring tool. Prior to version 4.5.2, the Glances REST API web server ships with a default CORS configuration that sets `allow_origins=["*"]` combined with `allow_credentials=True`. When both of these options are enabled together, Starlette's `CORSMiddleware` reflects the requesting `Origin` header value in the `Access-Control-Allow-Origin` response header instead of returning the literal `*` wildcard. This effectively grants any website the ability to make credentialed cross-origin API requests to the Glances server, enabling cross-site data theft of system monitoring information, configuration secrets, and command line arguments from any user who has an active browser session with a Glances instance. Version 4.5.2 fixes the issue.

Title
qui CORS Misconfiguration: Arbitrary Origins Trusted
Summary
qui is a web interface for managing qBittorrent instances. Versions 1.14.1 and below use a permissive CORS policy that reflects arbitrary origins while also returning Access-Control-Allow-Credentials: true, effectively allowing any external webpage to make authenticated requests on behalf of a logged-in user. An attacker can exploit this by tricking a victim into loading a malicious webpage, which silently interacts with the application using the victim's session and potentially exfiltrating sensitive data such as API keys and account credentials, or even achieving full system compromise through the built-in External Programs manager. Exploitation requires that the victim access the application via a non-localhost hostname and load an attacker-controlled webpage, making highly targeted social-engineering attacks the most likely real-world scenario. This issue was not fixed at the time of publication.

CVE-2026-28792 (GCVE-0-2026-28792)

Vulnerability from cvelistv5 – Published: 2026-03-12 16:48 – Updated: 2026-03-13 16:29

Title
Cross-Origin File Exfiltration via CORS Misconfiguration + Path Traversal in TinaCMS
Summary
Tina is a headless content management system. Prior to 2.1.8 , the TinaCMS CLI dev server combines a permissive CORS configuration (Access-Control-Allow-Origin: *) with the path traversal vulnerability (previously reported) to enable a browser-based drive-by attack. A remote attacker can enumerate the filesystem, write arbitrary files, and delete arbitrary files on developer's machines by simply tricking them into visiting a malicious website while tinacms dev is running. This vulnerability is fixed in 2.1.8.

Title
CollabPlatform : CORS Misconfiguration Allows Arbitrary Origin With Credentials Leading to Authenticated Account Data Exposure
Summary
CollabPlatform is a full-stack, real-time doc collaboration platform. In all versions of CollabPlatform, the Appwrite project used by the application is misconfigured to allow arbitrary origins in CORS responses while also permitting credentialed requests. An attacker-controlled domain can issue authenticated cross-origin requests and read sensitive user account information, including email address, account identifiers, and MFA status. The issue did not have a fix at the time of publication.

CVE-2026-25478 (GCVE-0-2026-25478)

Vulnerability from cvelistv5 – Published: 2026-02-09 18:46 – Updated: 2026-02-10 16:01
VLAI
Title
Litestar has a CORS origin allowlist bypass due to unescaped regex metacharacters in allowed origins
Summary
Litestar is an Asynchronous Server Gateway Interface (ASGI) framework. Prior to 2.20.0, CORSConfig.allowed_origins_regex is constructed using a regex built from configured allowlist values and used with fullmatch() for validation. Because metacharacters are not escaped, a malicious origin can match unexpectedly. The check relies on allowed_origins_regex.fullmatch(origin). This vulnerability is fixed in 2.20.0.

Title
Tenda W30E V2 Permissive CORS Allows Cross-origin Data Access
Summary
Shenzhen Tenda W30E V2 firmware versions up to and including V16.01.0.19(5037) implement an insecure Cross-Origin Resource Sharing (CORS) policy on authenticated administrative endpoints. The device sets Access-Control-Allow-Origin: * in combination with Access-Control-Allow-Credentials: true, allowing attacker-controlled origins to issue credentialed cross-origin requests.

CVE-2026-18676 (GCVE-0-2026-18676)

Title
Kong Mesh: default control plane config leaks the admin token cross-origin via a CORS wildcard and localhost admin
Summary
The default kuma-cp configuration in Kong Mesh reveals the admin bootstrap token and signing keys to any webpage the operator visits while the control plane is reachable from their browser. Due to a CORS misconfiguration a cross-origin fetch() from a malicious page returns the admin JWT and signing material.

Mitigation
Architecture and Design Operation

Strategy: Attack Surface Reduction

Define a restrictive Content Security Policy [REF-1486] or cross-domain policy file.

Mitigation
Architecture and Design Operation

Strategy: Attack Surface Reduction

Avoid using wildcards in the CSP / cross-domain policy file. Any domain matching the wildcard expression will be implicitly trusted, and can perform two-way interaction with the target server.

Mitigation
Architecture and Design Operation

Strategy: Environment Hardening

For Flash, modify crossdomain.xml to use meta-policy options such as 'master-only' or 'none' to reduce the possibility of an attacker planting extraneous cross-domain policy files on a server.
