CVE-2026-45712 Mailpit: Concurrent map read & write in proxy CSS rewriter - remote unauth crash (fatal error: concurrent map read and map write)

Mailpit is an email testing tool and API for developers. Prior to version 1.30.0, the screenshot/print proxy /proxy?data=… maintains a package-level assets mapstringMessageAssets cache, but reads the map without holding assetsMutex while a long-running cleanup goroutine and re-entrant CSS-rewriti...

CVE-2026-45712

CVE-2026-45712 concerns Mailpit's proxy CSS rewriter exposing a race condition: an unsynchronized read of a package-level assets map occurs concurrently with writes under the assetsMutex, causing a runtime panic (concurrent map read and map write) and a full Mailpit process crash, taking SMTP/POP...

CVE-2026-58055

A flaw in nghttp2's nghttpx proxy allows a remote attacker to perform HTTP request smuggling and cross-client response-queue poisoning. This occurs because the proxy ambiguously forwards HTTP/1.1 Upgrade requests that contain a Content-Length header to reusable keep-alive backend connections...

nodejs: Node.js: Information disclosure of proxy credentials via proxy tunnel error handling

A flaw was found in Node.js. When proxy credentials are embedded in a proxy URL, an issue in the proxy tunnel error handling can lead to the exposure of these credentials. This information disclosure vulnerability allows an attacker to potentially capture sensitive proxy credentials through logs,...

USN-8563-1: nginx vulnerabilities

It was discovered that nginx incorrectly handled certain map directives using regex matching and capture variables. A remote attacker could use this issue to cause nginx to crash, resulting in a denial of service, or possibly execute arbitrary code. CVE-2026-42533 It was discovered that nginx had...

axios: Axios: Information disclosure of proxy credentials via redirect flows

A flaw was found in Axios. During specific proxy-to-direct redirect flows in the Node.js HTTP adapter, a remote attacker could exploit this vulnerability. The Proxy-Authorization header, which contains proxy credentials and is intended only for the outbound proxy, may be forwarded to the final...

axios: Axios: Proxy bypass via IPv4-mapped IPv6 address non-normalization

A flaw was found in Axios, a promise-based HTTP client. This vulnerability occurs because Axios does not properly normalize IPv4-mapped IPv6 addresses. When a NOPROXY setting is configured to block direct access to specific IPv4 addresses, an attacker can bypass this restriction by using the...

webpack-dev-server: webpack-dev-server: Information disclosure and denial of service via improper proxy configuration

A flaw was found in webpack-dev-server. When a user configures a proxy with a broad context, such as '/', and enables WebSocket ws: true forwarding, the development server's own Hot Module Replacement HMR WebSocket can be intercepted. This interception leads to the leakage of the browser's cookie...

axios: Axios: Information disclosure of proxy credentials via HTTP redirects

A flaw was found in Axios, a promise-based HTTP client, specifically in its Node.js HTTP adapter. When Axios is configured to use an authenticated proxy and follows a redirect, it may inadvertently send the Proxy-Authorization header, containing proxy credentials, to the redirect target. This can...

netty-codec-haproxy: Netty HAProxy PROXY protocol v2 codec: Denial of Service via memory leak from crafted PROXY protocol headers

A flaw was found in the Netty HAProxy PROXY protocol v2 codec. A remote attacker can exploit this vulnerability by sending a specially crafted HAProxy PROXY protocol v2 header with nested PP2TYPESSL type-length-value TLV records. This can lead to a memory leak, causing the underlying cumulation...

axios: Axios: Man-in-the-Middle (MITM) attack via Prototype Pollution

A flaw was found in Axios. This vulnerability, a Prototype Pollution "Gadget" attack, allows an attacker to escalate any existing Object.prototype pollution in an application's dependency tree into a full Man-in-the-Middle MITM attack. This enables the attacker to intercept, read, and modify all...

CVE-2026-16242

A flaw was found in the Konnectivity proxy-server configuration for hosted control planes. The agent-facing listener was started without --cluster-ca-cert and without token-based agent authentication, so client certificates were not validated. A remote attacker who can reach the Konnectivity...
