CVE-2023-29141 2 Fedoraproject, Mediawiki 2 Fedora, Mediawiki 2026-06-17 N/A 9.8 CRITICAL
An issue was discovered in MediaWiki before 1.35.10, 1.36.x through 1.38.x before 1.38.6, and 1.39.x before 1.39.3. An auto-block can occur for an untrusted X-Forwarded-For header.
CVE-2023-27522 3 Apache, Debian, Unbit 3 Http Server, Debian Linux, Uwsgi 2026-06-17 N/A 7.5 HIGH
HTTP Response Smuggling vulnerability in Apache HTTP Server via mod_proxy_uwsgi. This issue affects Apache HTTP Server: from 2.4.30 through 2.4.55. Special characters in the origin response header can truncate/split the response forwarded to the client.
CVE-2023-27493 1 Envoyproxy 1 Envoy 2026-06-17 N/A 8.1 HIGH
Envoy is an open source edge and service proxy designed for cloud-native applications. Prior to versions 1.26.0, 1.25.3, 1.24.4, 1.23.6, and 1.22.9, Envoy does not sanitize or escape request properties when generating request headers. This can lead to characters that are illegal in header values to be sent to the upstream service. In the worst case, it can cause upstream service to interpret the original request as two pipelined requests, possibly bypassing the intent of Envoy’s security policy. Versions 1.26.0, 1.25.3, 1.24.4, 1.23.6, and 1.22.9 contain a patch. As a workaround, disable adding request headers based on the downstream request properties, such as downstream certificate properties.
CVE-2023-27491 1 Envoyproxy 1 Envoy 2026-06-17 N/A 5.4 MEDIUM
Envoy is an open source edge and service proxy designed for cloud-native applications. Compliant HTTP/1 service should reject malformed request lines. Prior to versions 1.26.0, 1.25.3, 1.24.4, 1.23.6, and 1.22.9, There is a possibility that non compliant HTTP/1 service may allow malformed requests, potentially leading to a bypass of security policies. This issue is fixed in versions 1.26.0, 1.25.3, 1.24.4, 1.23.6, and 1.22.9.
CVE-2023-27238 1 Lavalite 1 Lavalite 2026-06-17 N/A 9.8 CRITICAL
LavaLite CMS v 9.0.0 was discovered to be vulnerable to web cache poisoning.
CVE-2023-26137 1 Drogon 1 Drogon 2026-06-17 N/A 7.2 HIGH
All versions of the package drogonframework/drogon are vulnerable to HTTP Response Splitting when untrusted user input is used to build header values in the addHeader and addCookie functions. An attacker can add the \r\n (carriage return line feeds) characters to end the HTTP response headers and inject malicious content.
CVE-2023-25950 1 Haproxy 1 Haproxy 2026-06-17 N/A 7.3 HIGH
HTTP request/response smuggling vulnerability in HAProxy version 2.7.0, and 2.6.1 to 2.6.7 allows a remote attacker to alter a legitimate user's request. As a result, the attacker may obtain sensitive information or cause a denial-of-service (DoS) condition.
CVE-2023-25725 2 Debian, Haproxy 2 Debian Linux, Haproxy 2026-06-17 N/A 9.1 CRITICAL
HAProxy before 2.7.3 may allow a bypass of access control because HTTP/1 headers are inadvertently lost in some situations, aka "request smuggling." The HTTP header parsers in HAProxy may accept empty header field names, which could be used to truncate the list of HTTP headers and thus make some headers disappear after being parsed and processed for HTTP/1.0 and HTTP/1.1. For HTTP/2 and HTTP/3, the impact is limited because the headers disappear before being parsed and processed, as if they had not been sent by the client. The fixed versions are 2.7.3, 2.6.9, 2.5.12, 2.4.22, 2.2.29, and 2.0.31.
CVE-2023-25690 1 Apache 1 Http Server 2026-06-17 N/A 9.8 CRITICAL
Some mod_proxy configurations on Apache HTTP Server versions 2.4.0 through 2.4.55 allow a HTTP Request Smuggling attack. Configurations are affected when mod_proxy is enabled along with some form of RewriteRule or ProxyPassMatch in which a non-specific pattern matches some portion of the user-supplied request-target (URL) data and is then re-inserted into the proxied request-target using variable substitution. For example, something like: RewriteEngine on RewriteRule "^/here/(.*)" "http://example.com:8080/elsewhere?$1"; [P] ProxyPassReverse /here/ http://example.com:8080/ Request splitting/smuggling could result in bypass of access controls in the proxy server, proxying unintended URLs to existing origin servers, and cache poisoning. Users are recommended to update to at least version 2.4.56 of Apache HTTP Server.
CVE-2023-23691 1 Dell 6 Powervault Me5012, Powervault Me5012 Firmware, Powervault Me5024 and 3 more 2026-06-17 N/A 8.1 HIGH
Dell EMC PV ME5, versions ME5.1.0.0.0 and ME5.1.0.1.0, contains a Client-side desync Vulnerability. An unauthenticated attacker could potentially exploit this vulnerability to force a victim's browser to desynchronize its connection with the website, typically leading to XSS and DoS.
CVE-2022-45059 2 Fedoraproject, Varnish Cache Project 2 Fedora, Varnish Cache 2026-06-17 N/A 7.5 HIGH
An issue was discovered in Varnish Cache 7.x before 7.1.2 and 7.2.x before 7.2.1. A request smuggling attack can be performed on Varnish Cache servers by requesting that certain headers are made hop-by-hop, preventing the Varnish Cache servers from forwarding critical headers to the backend.
CVE-2022-42252 1 Apache 1 Tomcat 2026-06-17 N/A 7.5 HIGH
If Apache Tomcat 8.5.0 to 8.5.82, 9.0.0-M1 to 9.0.67, 10.0.0-M1 to 10.0.26 or 10.1.0-M1 to 10.1.0 was configured to ignore invalid HTTP headers via setting rejectIllegalHeader to false (the default for 8.5.x only), Tomcat did not reject a request containing an invalid Content-Length header making a request smuggling attack possible if Tomcat was located behind a reverse proxy that also failed to reject the request with the invalid header.
CVE-2022-41721 1 Golang 1 H2c 2026-06-17 N/A 7.5 HIGH
A request smuggling attack is possible when using MaxBytesHandler. When using MaxBytesHandler, the body of an HTTP request is not fully consumed. When the server attempts to read HTTP2 frames from the connection, it will instead be reading the body of the HTTP request, which could be attacker-manipulated to represent arbitrary HTTP2 requests.
CVE-2022-39163 2 Ibm, Microsoft 3 Cognos Controller, Controller, Windows 2026-06-17 N/A 4.7 MEDIUM
IBM Cognos Controller 11.0.0 through 11.1.0 is vulnerable to a Client-Side Desync (CSD) attack where an attacker could exploit a desynchronized browser connection that could lead to further cross-site scripting (XSS) attacks.
CVE-2022-38114 1 Solarwinds 1 Security Event Manager 2026-06-17 N/A 6.1 MEDIUM
This vulnerability occurs when a web server fails to correctly process the Content-Length of POST requests. This can lead to HTTP request smuggling or XSS.
CVE-2022-36760 1 Apache 1 Http Server 2026-06-17 N/A 9.0 CRITICAL
Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling') vulnerability in mod_proxy_ajp of Apache HTTP Server allows an attacker to smuggle requests to the AJP server it forwards requests to. This issue affects Apache HTTP Server Apache HTTP Server 2.4 version 2.4.54 and prior versions.
CVE-2022-35256 4 Debian, Llhttp, Nodejs and 1 more 4 Debian Linux, Llhttp, Node.js and 1 more 2026-06-17 N/A 6.5 MEDIUM
The llhttp parser in the http module in Node v18.7.0 does not correctly handle header fields that are not terminated with CLRF. This may result in HTTP Request Smuggling.
CVE-2022-33988 1 Dproxy-nexgen Project 1 Dproxy-nexgen 2026-06-17 N/A 7.5 HIGH
dproxy-nexgen (aka dproxy nexgen) re-uses the DNS transaction id (TXID) value from client queries, which allows attackers (able to send queries to the resolver) to conduct DNS cache-poisoning attacks because the TXID value is known to the attacker.
CVE-2022-32215 6 Debian, Fedoraproject, Llhttp and 3 more 6 Debian Linux, Fedora, Llhttp and 3 more 2026-06-17 N/A 6.5 MEDIUM
The llhttp parser <v14.20.1, <v16.17.1 and <v18.9.1 in the http module in Node.js does not correctly handle multi-line Transfer-Encoding headers. This can lead to HTTP Request Smuggling (HRS).
CVE-2022-32214 4 Debian, Llhttp, Nodejs and 1 more 4 Debian Linux, Llhttp, Node.js and 1 more 2026-06-17 N/A 6.5 MEDIUM
The llhttp parser <v14.20.1, <v16.17.1 and <v18.9.1 in the http module in Node.js does not strictly use the CRLF sequence to delimit HTTP requests. This can lead to HTTP Request Smuggling (HRS).
