| CVE-2026-34839 | 1 Nicolargo | 1 Glances | 2026-04-21 | N/A |
| Glances is an open-source system cross-platform monitoring tool. Prior to version 4.5.4, the Glances web server exposes a REST API (`/api/4/*`) that is accessible without authentication and allows cross-origin requests from any origin due to a permissive CORS policy (`Access-Control-Allow-Origin: *`). This allows a malicious website to read sensitive system information from a running Glances instance in the victim’s browser, leading to cross-origin data exfiltration. While a previous advisory exists for XML-RPC CORS issues, this report demonstrates that the REST API (`/api/4/*`) is also affected and exposes significantly more sensitive data. Version 4.5.4 patches the issue. | ||||

| A vulnerability was found in ericc-ch copilot-api up to 0.7.0. The impacted element is the function cors of the file src/server.ts of the component Token Endpoint. Performing a manipulation results in permissive cross-domain policy with untrusted domains. It is possible to initiate the attack remotely. The exploit has been made public and could be used. | ||||
| CVE-2025-10529 | 2 Mozilla, Redhat | 4 Firefox, Firefox Esr, Thunderbird and 1 more | 2026-04-20 | 6.5 Medium |
| Same-origin policy bypass in the Layout component. This vulnerability was fixed in Firefox 143, Firefox ESR 140.3, Thunderbird 143, and Thunderbird 140.3. | ||||
| CVE-2026-1181 | 1 Altium | 1 Altium 365 | 2026-04-18 | 9 Critical |
| Altium 365 workspace endpoints were configured with an overly permissive Cross-Origin Resource Sharing (CORS) policy that allowed credentialed cross-origin requests from other Altium-controlled subdomains, including forum.live.altium.com. As a result, JavaScript executing on those origins could access authenticated workspace APIs in the context of a logged-in user. When chained with vulnerabilities in those external applications, this misconfiguration enables unauthorized access to workspace data, administrative actions, and bypass of IP allowlisting controls, including in GovCloud environments. | ||||
| CVE-2026-25478 | 2 Litestar, Litestar-org | 2 Litestar, Litestar | 2026-04-18 | 7.4 High |
| 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. | ||||
| CVE-2026-22812 | 2 Anoma, Anomalyco | 2 Opencode, Opencode | 2026-04-18 | 8.8 High |
| OpenCode is an open source AI coding agent. Prior to 1.0.216, OpenCode automatically starts an unauthenticated HTTP server that allows any local process (or any website via permissive CORS) to execute arbitrary shell commands with the user's privileges. This vulnerability is fixed in 1.0.216. | ||||
| CVE-2026-27579 | 1 Karnop | 1 Realtime-collaboration-platform | 2026-04-18 | 7.4 High |
| 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-2026-24435 | 1 Tenda | 2 W30e, W30e Firmware | 2026-04-16 | 6.5 Medium |
| 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-2026-5302 | 1 Coolercontrol | 1 Coolercontrold | 2026-04-16 | 6.3 Medium |
| CORS misconfiguration in CoolerControl/coolercontrold <4.0.0 allows unauthenticated remote attackers to read data and send commands to the service via malicious websites | ||||
| CVE-2026-30924 | 2 Autobrr, Getqui | 2 Qui, Qui | 2026-04-15 | 8.8 High |
| 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-2026-33010 | 1 Doobidoo | 1 Mcp-memory-service | 2026-04-15 | 8.1 High |
| mcp-memory-service is an open-source memory backend for multi-agent systems. Prior to version 10.25.1, when the HTTP server is enabled (MCP_HTTP_ENABLED=true), the application configures FastAPI's CORSMiddleware with allow_origins=['*'], allow_credentials=True, allow_methods=["*"], and allow_headers=["*"]. The wildcard Access-Control-Allow-Origin: * header permits any website to read API responses cross-origin. When combined with anonymous access (MCP_ALLOW_ANONYMOUS_ACCESS=true) - the simplest way to get the HTTP dashboard working without OAuth - no credentials are needed, so any malicious website can silently read, modify, and delete all stored memories. This issue has been patched in version 10.25.1. | ||||
| CVE-2026-0397 | 1 Powerdns | 1 Dnsdist | 2026-04-15 | 3.1 Low |
| When the internal webserver is enabled (default is disabled), an attacker might be able to trick an administrator logged to the dashboard into visiting a malicious website and extract information about the running configuration from the dashboard. The root cause of the issue is a misconfiguration of the Cross-Origin Resource Sharing (CORS) policy. | ||||
| CVE-2024-53276 | 2026-04-15 | N/A | ||
| Home-Gallery.org is a self-hosted open-source web gallery to browse personal photos and videos. In 1.15.0 and earlier, an open CORS policy in app.js may allow an attacker to view the images of home-gallery when it is using the default settings. The following express middleware allows any website to make a cross site request to home-gallery, thus allowing them to read any endpoint on home-gallery. Home-gallery is mostly safe from cross-site requests due to most of its pages requiring JavaScript, and cross-site requests such as fetch() do not render javascript. If an attacker is able to get the path of the preview images which are randomized, an attacker will be able to view such a photo. If any static files or endpoints are introduced in the future that contain sensitive information, they will be accessible to an attacker website. | ||||
| CVE-2020-36851 | 2026-04-15 | N/A | ||
| Rob -- W / cors-anywhere instances configured as an open proxy allow unauthenticated external users to induce the server to make HTTP requests to arbitrary targets (SSRF). Because the proxy forwards requests and headers, an attacker can reach internal-only endpoints and link-local metadata services, retrieve instance role credentials or other sensitive metadata, and interact with internal APIs and services that are not intended to be internet-facing. The vulnerability is exploitable by sending crafted requests to the proxy with the target resource encoded in the URL; many cors-anywhere deployments forward arbitrary methods and headers (including PUT), which can permit exploitation of IMDSv2 workflows as well as access to internal management APIs. Successful exploitation can result in theft of cloud credentials, unauthorized access to internal services, remote code execution or privilege escalation (depending on reachable backends), data exfiltration, and full compromise of cloud resources. Mitigation includes: restricting the proxy to trusted origins or authentication, whitelisting allowed target hosts, preventing access to link-local and internal IP ranges, removing support for unsafe HTTP methods/headers, enabling cloud provider mitigations, and deploying network-level protections. | ||||
| CVE-2025-41363 | 2026-04-15 | N/A | ||
| In IDF v0.10.0-0C03-03 and ZLF v0.10.0-0C03-04, a configuration error has been detected in cross-origin resource sharing (CORS). Exploiting this vulnerability requires authenticating to the device and executing certain commands that can be executed with view permission. | ||||
| CVE-2023-37526 | 2026-04-15 | 6.5 Medium | ||
| HCL DRYiCE Lucy (now AEX) is affected by a Cross Origin Resource Sharing (CORS) vulnerability. The mobile app is vulnerable to a CORS misconfiguration which could potentially allow unauthorized access to the application resources from any web domain and enable cache poisoning attacks. | ||||
| CVE-2025-57755 | 2026-04-15 | N/A | ||
| claude-code-router is a powerful tool to route Claude Code requests to different models and customize any request. Due to improper Cross-Origin Resource Sharing (CORS) configuration, there is a risk that user API Keys or equivalent credentials may be exposed to untrusted domains. Attackers could exploit this misconfiguration to steal credentials, abuse accounts, exhaust quotas, or access sensitive data. The issue has been patched in v1.0.34. | ||||
| CVE-2024-10315 | 2026-04-15 | N/A | ||
| In Gliffy Online an insecure configuration was discovered in versions before 4.14.0-6. Reported by Alpha Inferno PVT LTD. | ||||
