A weakness in Cesanta Mongoose up to 7.21 can lead to a stack-based buffer overflow in the MQTT Broker component. The CVE record indicates that upgrading to version 7.22 addresses this issue. The NVD entry is currently being reviewed for additional details. Defenders should verify exposure in MQTT Broker deployments using Cesanta Mongoose up to 7.21 and prioritize upgrading to version 7.22 if vulnerable. [truncated]
A reflected cross-site scripting vulnerability exists in Mongoose, an embedded web server and network library, prior to version 7.22. This issue allows a remote attacker to send a crafted percent-encoded request path to a deployment using MG_ENABLE_DIRLIST, potentially persuading a user to visit it. The vulnerability is due to the mg_http_serve_dir() and listdir() paths in src/http.c placing the decoded r [truncated]
CVE-2026-73258 is a vulnerability in the Mongoose embedded web server and network library. A remote attacker can place a lone carriage return or line feed in multipart input processed by mg_http_next_multipart() in src/http.c, which can cause an application to accept dangerous content after seeing a misleading Content-Type value. This issue is fixed in version 7.22.
A critical vulnerability exists in Mongoose, an embedded web server and network library, prior to version 7.22. This issue allows a remote unauthenticated attacker to send an HTTP request containing both Content-Length and Transfer-Encoding: chunked headers, potentially leading to CL.TE desynchronization. This desynchronization can inject requests that access or modify resources in another user context.
Mongoose, an embedded web server and network library, is vulnerable to request smuggling in HTTP/1.0 reverse-proxy deployments prior to version 7.22. The issue arises from improper handling of Transfer-Encoding: chunked requests with conflicting framing, allowing remote unauthenticated attackers to potentially access or change system state. Organizations should review their deployments, especially those u [truncated]
CVE-2026-73255 debrief based on CVE Program and NVD records. Mongoose embedded web server and network library has a directory traversal vulnerability prior to version 7.22. An attacker controlling an SSI-enabled file can disclose files readable by the Mongoose process via #include directives. This issue is fixed in version 7.22. The vulnerability allows an attacker to access files outside the intended dir [truncated]
AI-assisted PatchSiren debrief based on the supplied source corpus. The CVE record was published on 2026-08-20T18:16:46.113Z and has not been modified since then. Mongoose is an embedded web server and network library with a stored cross-site scripting vulnerability prior to version 7.22. An attacker who can create a file with an HTML payload in its name can trigger stored cross-site scripting when a user [truncated]
CVE-2026-73253 is a critical vulnerability in the Mongoose embedded web server and network library. An on-path network attacker with a wildcard certificate for a parent domain can impersonate deeper subdomains to a client using the built-in TLS stack. This issue allows for hostname verification bypass, permitting interception and modification of TLS traffic. The vulnerability is fixed in version 7.22. Net [truncated]
A critical vulnerability in the Mongoose embedded web server and network library allows a network attacker to impersonate a TLS server to a Mongoose client configured with a multi-certificate CA bundle. The mg_tls_init() function stores the bundle in tls->ca_bundle_der while tls->ca_der.len remains zero, and mg_tls_recv_cert() uses tls_bundle_find() to accept a Common Name match without calling mg_tls_ver [truncated]
CVE-2026-11404 is a high-severity vulnerability in Cesanta Mongoose, a popular embedded web server. The vulnerability exists in the built-in TLS server function mg_tls_server_recv_hello(), which does not properly validate the session_id_len byte from a TLS ClientHello. This allows a remote, unauthenticated attacker to send a crafted ClientHello with an oversized session id length, causing the server to re [truncated]
