Oct 21, 2026HAProxy 3 before 3.4.6 allows a remote unauthenticated attacker to cause a denial of service (persistent worker-thread CPU exhaustion) via an HTTP/1.1 chunked rCVE-2026-110354 · Other software · HAProxy · reported by MITREHigh 7.5
HAProxy 3 before 3.4.6 allows a remote unauthenticated attacker to cause a denial of service (persistent worker-thread CPU exhaustion) via an HTTP/1.1 chunked request. Although the H1 multiplexer drains the request before closing the stream, the parser repeatedly re-processes the same bytes without making progress. The affected thread stays busy at 100% CPU after timeouts expire and after the client disconnects, and repeated requests can consume all worker threads until the process is restarted.

Oct 21, 2026HAProxy 3.2 before 3.4.6 allows a remote unauthenticated attacker to cause a denial of service (worker-thread CPU exhaustion) via a truncated HTTP/2 PING frame.CVE-2026-110353 · Other software · HAProxy · reported by MITREHigh 7.5
HAProxy 3.2 before 3.4.6 allows a remote unauthenticated attacker to cause a denial of service (worker-thread CPU exhaustion) via a truncated HTTP/2 PING frame. h2c_handle_ping in src/mux_h2.c does not check for a short read, unlike the other H2 frame handlers. Because the incomplete frame cannot be processed, its data is never consumed, and the H2 multiplexer tasklet is repeatedly woken by that pending data without making progress. The CPU spins until timeout http-request closes the connection, and an attacker opening many such connections can sustain high CPU usage.

In HAProxy Data Plane API 2.2.0 through 3.4.3 (and corresponding Enterprise Edition releases), Server.ConfigureAPI() has process-global authentication logic that improperly drops security controls across multiple transport types. When a TLS Certificate Authority (tls_ca) is configured and a numeric TLS port (tls_port) is specified, the application globally disables Basic authentication on its shared internal request handler. Because this handler is shared concurrently among HTTP, HTTPS, and UNIX domain socket listeners, and mutual TLS (mTLS) client certificate verification (tls.RequireAndVerifyClientCert) is enforced exclusively on the HTTPS server path, all other simultaneously active non-mTLS listeners fail open. Consequently, an unauthenticated attacker capable of reaching an affected HTTP or UNIX management endpoint can completely bypass credentials to gain full API administrative access. This allows unauthorized remote or local actors to read sensitive, cleartext HAProxy configuration data or replace the managed configuration entirely via the raw configuration endpoint. This has been fixed in versions 3.4.4, 3.3.9, 3.2.17, 3.0.25, 2.9.29, and their respective EE backports by m

Sep 13, 2026An issue was discovered in HAProxy 3.3.0 through 3.4.4 and in 3.5-dev1 through 3.5-dev5.CVE-2026-90678 · Other software · HAProxy · reported by MITREHigh 7.5
An issue was discovered in HAProxy 3.3.0 through 3.4.4 and in 3.5-dev1 through 3.5-dev5. Exploitation requires an HTTP/3 frontend: HAProxy must be built with QUIC support and configured with a QUIC bind listener, and the affected traffic must reach a backend over HTTP/1.1 using chunked transfer coding on a reused connection. Under those conditions, when an HTTP/3 request carries no Content-Length header, the HTTP/3 multiplexer credits the length declared in a DATA frame header to the stream endpoint's known-input-payload estimate at the moment the frame header is decoded, before the payload has been received, and that declared length is emitted verbatim as the HTTP/1.1 chunk size. A remote unauthenticated client that declares more payload than it delivers and then ends the stream causes HAProxy to announce a chunk larger than the bytes it writes and to return the connection to the idle pool in a desynchronized state. The result is potential HTTP request smuggling on reused backend connections: an attacker can place a request past a frontend rule such as a path-based http-request deny, so that the smuggled request is never seen by HAProxy's HTTP analysis, and can cause concurrent cl

In versions 8.2.6.4 and prior, ommit d4d10006 ("Expand validation to block .. in config_file_name and configver for improved security") added a line in app/modules/config/config.py:462. This is tuple-membership, not substring containment — '..' in (a, b, c) evaluates to True only if any of a, b, c is equal to the literal string '..'. For any realistic path-traversal payload (../../etc/passwd, ..\\..\\etc\\passwd, etc.) the check returns False and the patch silently lets the payload through.

Roxy-WI is a web interface for managing Haproxy, Nginx, Apache and Keepalived servers. In versions 8.2.6.4 and prior, the HAProxy section-save endpoints (POST /api/service/haproxy/<server_id>/section/<section_type> and the PUT / global / defaults variants) accept a JSON option field that is not validated, not escaped, and is rendered verbatim into the generated HAProxy configuration via the section.j2, global.j2, and defaults.j2 Ansible templates. Because Roxy-WI then pushes the generated config to the load balancer and runs systemctl reload haproxy, an authenticated user with role ≤ 3 (user) can inject arbitrary HAProxy directives into the config that runs on every load balancer their group manages — including option external-check + external-check command /bin/bash -c '…', which gives remote code execution on the load balancer as the haproxy user on every health-check tick.

Roxy-WI is a web interface for managing Haproxy, Nginx, Apache and Keepalived servers.

Roxy-WI is a web interface for managing Haproxy, Nginx, Apache and Keepalived servers. Prior to version 8.2.6.4, the POST /config/<service>/show API endpoint accepts a configver parameter that is directly appended to a base directory path to construct a local file path, which is subsequently opened and its contents returned to the caller.

Aug 29, 2024Roxy-WI is a web interface for managing Haproxy, Nginx, Apache and Keepalived servers.CVE-2024-43804 · Other software · roxy-wi · reported by GitHubHigh 8.8
Roxy-WI is a web interface for managing Haproxy, Nginx, Apache and Keepalived servers. An OS Command Injection vulnerability allows any authenticated user on the application to execute arbitrary code on the web application server via port scanning functionality. User-supplied input is used without validation when constructing and executing an OS command. User supplied JSON POST data is parsed and if "id" JSON key does not exist, JSON value supplied via "ip" JSON key is assigned to the "ip" variable. Later on, "ip" variable which can be controlled by the attacker is used when constructing the cmd and cmd1 strings without any extra validation. Then, server_mod.subprocess_execute function is called on both cmd1 and cmd2. When the definition of the server_mod.subprocess_execute() function is analyzed, it can be seen that subprocess.Popen() is called on the input parameter with shell=True which results in OS Command Injection. This issue has not yet been patched. Users are advised to contact the Roxy-WI to coordinate a fix.

hap-wi/roxy-wi is a web interface for managing Haproxy, Nginx, Apache and Keepalived servers. A Path Traversal vulnerability was found in the current version of Roxy-WI (6.3.9.0 at the moment of writing this report). The vulnerability can be exploited via an HTTP request to /app/options.py and the config_file_name parameter. Successful exploitation of this vulnerability could allow an attacker with user level privileges to obtain the content of arbitrary files on the file server within the scope of what the server process has access to. The root-cause of the vulnerability lies in the get_config function of the /app/modules/config/config.py file, which only checks for relative path traversal, but still allows to read files from absolute locations passed via the config_file_name parameter.
