CVE-2026-9595 1 Webpack.js 1 Webpack-dev-server 2026-06-17 N/A 5.3 MEDIUM
Impact: When a user-configured proxy on webpack-dev-server has a broad context (e.g. /) and ws: true, it also intercepts the dev server's own HMR WebSocket and forwards it to the proxy target. This leaks the browser's cookies and Origin header to the backend, bypasses the dev server's Host/Origin validation, and corrupts the HMR socket (both HMR and the proxy end up writing to the same socket). Patches: Fixed in webpack-dev-server@5.2.5. Workarounds: Scope user-defined proxy context to specific paths instead of /, or omit ws: true from the proxy entry when WebSocket forwarding is not required.

CVE-2026-7643 2026-06-17 5.0 MEDIUM 4.3 MEDIUM
A flaw has been found in ChatGPTNextWeb NextChat up to 2.16.1. This impacts an unknown function of the file Next.js of the component API Endpoint. Executing a manipulation can lead to permissive cross-domain policy with untrusted domains. The attack may be launched remotely. The exploit has been published and may be used. The project was informed of the problem early through an issue report but has not responded yet.
CVE-2026-7581 2026-06-17 5.0 MEDIUM 4.3 MEDIUM
A security vulnerability has been detected in alexta69 MeTube up to 2026.04.09. This affects the function on_prepare of the file app/main.py of the component CORS Policy. The manipulation leads to permissive cross-domain policy with untrusted domains. The attack is possible to be carried out remotely. The exploit has been disclosed publicly and may be used. Upgrading to version 2026.04.10 is able to mitigate this issue. The identifier of the patch is 0072d3488ae5b8d922d3ee87458d829993742a32. It is recommended to upgrade the affected component.
CVE-2026-7439 2026-06-17 N/A 4.4 MEDIUM
AgentFlow's local web API accepts non-JSON content types on POST /api/runs and POST /api/runs/validate endpoints without enforcing application/json validation, allowing attackers to bypass trust-boundary enforcement on sensitive operations. Attackers can exploit this content-type validation weakness through browser-driven or local cross-origin requests to abuse the localhost API and enable attack chains against the local control plane.
CVE-2026-6903 2026-06-17 N/A 7.5 HIGH
The LabOne Web Server, backing the LabOne User Interface, contains insufficient input validation in its file access functionality. An unauthenticated attacker could exploit this vulnerability to read arbitrary files on the host system that are accessible to the operating system user running the LabOne software. Additionally, the Web Server does not sufficiently restrict cross-origin requests, which could allow a remote attacker to trigger file access from a victim's browser by directing the victim to a malicious website. The vulnerability is only exploitable when the LabOne Web Server is running. Installations using only the LabOne APIs without starting the Web Server are not exposed.
CVE-2026-6662 2026-06-17 7.5 HIGH 7.3 HIGH
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-2026-6508 2026-06-17 N/A 9.8 CRITICAL
Origin Validation Error vulnerability in TUBITAK BILGEM Software Technologies Research Institute Liderahenk allows Accessing Functionality Not Properly Constrained by ACLs. This issue affects Liderahenk: from 2.0.1 before 2.0.2.
CVE-2026-6339 1 Mattermost 1 Mattermost Server 2026-06-17 N/A 4.3 MEDIUM
Mattermost versions 11.5.x <= 11.5.1, 11.4.x <= 11.4.3 fail to validate the X-Requested-With header on the burn-on-read reveal endpoint which allows an authenticated channel member to force the reveal of a burn-on-read message without recipient consent via a crafted Markdown image tag.. Mattermost Advisory ID: MMSA-2026-00636
CVE-2026-6143 2026-06-17 6.5 MEDIUM 6.3 MEDIUM
A security flaw has been discovered in farion1231 cc-switch up to 3.12.3. Affected by this issue is some unknown functionality of the file src-tauri/src/proxy/server.rs of the component ProxyServer. The manipulation results in permissive cross-domain policy with untrusted domains. The attack can be executed remotely. The exploit has been released to the public and may be used for attacks.
CVE-2026-5918 4 Apple, Google, Linux and 1 more 4 Macos, Chrome, Linux Kernel and 1 more 2026-06-17 N/A 4.3 MEDIUM
Inappropriate implementation in Navigation in Google Chrome prior to 147.0.7727.55 allowed a remote attacker who had compromised the renderer process to leak cross-origin data via a crafted HTML page. (Chromium security severity: Low)
CVE-2026-5899 4 Apple, Google, Linux and 1 more 4 Macos, Chrome, Linux Kernel and 1 more 2026-06-17 N/A 6.1 MEDIUM
Insufficient policy enforcement in History Navigation in Google Chrome prior to 147.0.7727.55 allowed a remote attacker who convinced a user to engage in specific UI gestures to inject arbitrary scripts or HTML (UXSS) via a crafted HTML page. (Chromium security severity: Low)
CVE-2026-5321 2026-06-17 4.0 MEDIUM 4.3 MEDIUM
A flaw has been found in vanna-ai vanna up to 2.0.2. Affected by this issue is some unknown functionality of the component FastAPI/Flask Server. Executing a manipulation can lead to permissive cross-domain policy with untrusted domains. The attack can be launched remotely. The exploit has been published and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
CVE-2026-5283 4 Apple, Google, Linux and 1 more 4 Macos, Chrome, Linux Kernel and 1 more 2026-06-17 N/A 6.5 MEDIUM
Inappropriate implementation in ANGLE in Google Chrome prior to 146.0.7680.178 allowed a remote attacker to leak cross-origin data via a crafted HTML page. (Chromium security severity: High)
CVE-2026-47265 1 Aiohttp 1 Aiohttp 2026-06-17 N/A 7.5 HIGH
AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to version 3.14.0, cookies set with the `cookies` parameter on requests are sent after following a cross-origin redirect. If a developer uses the `cookies` parameter on a per-request basis then sensitive data might be leaked to an attacker if they manage to control a redirect. Version 3.14.0 patches the issue. If unable to upgrade, using a `Cookie` header in the `headers` parameter is not vulnerable.
CVE-2026-46685 2026-06-17 N/A N/A
RustFS is a distributed object storage system built in Rust. Prior to 1.0.0-beta.2, when RUSTFS_CORS_ALLOWED_ORIGINS is unset, the RustFS S3 listener's ConditionalCorsLayer reflects any request Origin value back as Access-Control-Allow-Origin and also sets Access-Control-Allow-Credentials: true and Access-Control-Allow-Headers: * on responses, including preflight responses and error responses. This creates a permissive cross-domain policy with untrusted origins. A browser visiting an attacker-controlled page can issue credentialed cross-origin requests to a reachable RustFS deployment and read the response when the victim browser has ambient credentials for the RustFS origin, such as saved HTTP Basic Auth credentials, reverse-proxy SSO cookies, or TLS client certificates. This vulnerability is fixed in 1.0.0-beta.2.
CVE-2026-45207 1 Trendmicro 1 Apex One 2026-06-17 N/A 7.8 HIGH
An origin validation vulnerability in the Apex One/SEP agent could allow a local attacker to escalate privileges on affected installations. This is similar to CVE-2026-45206 but exists in a different process protection communication mechanism. Please note: an attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.
