CVE Severity Published▾ Status Exploitation Description
CVE-2026-107806 Critical 2026-10-09 Not applicable Proof of concept only Nginx UI is a web user interface for the Nginx web server. From 2.3.8 until 2.5.0, an authenticated administrator with an active secure session can submit attacker-controlled portable backup key material and a matching manifest to POST /api/restore. The restore flow trusts the supplied key, decrypts attacker-controlled contents, and replaces the live app.ini, including protected nginx command settings such as TestConfigCmd. Triggering POST /api/nginx/test then executes the restored command in the Nginx UI runtime context, affecting confidentiality, integrity, and availability. This issue is fixed in version 2.5.0.
CVE-2026-42533 Critical 2026-07-15 Not applicable Proof of concept only A vulnerability exists in NGINX Plus and NGINX Open Source when a map directive uses regex matching and a string expression references the map's regex capture variables before referencing the map output variable. Alternatively, the same result could be achieved by using a non-cacheable variable in a string expression under certain conditions. An unauthenticated attacker along with conditions beyond their control can exploit this vulnerability by sending crafted HTTP requests. This may cause a heap buffer overflow in the NGINX worker process leading to a restart. Additionally, attackers can execute code on systems with Address Space Layout Randomization (ASLR) disabled or when the attacker can bypass ASLR. Impact: This vulnerability may allow remote attackers to cause a denial-of-service (DoS) on the NGINX system or to possibly trigger a code execution. There is no control plane exposure; this is a data plane issue only.  Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
CVE-2026-42530 Critical 2026-06-17 Not applicable Proof of concept only NGINX Open Source has a vulnerability in the ngx_http_v3_module module. When NGINX Open Source is configured to use the HTTP/3 QUIC module, a remote unauthenticated attacker along with conditions beyond their control can use a specially crafted HTTP/3 session to reopen a QPACK encoder stream. This may cause a Use-after-Free in the NGINX worker process leading to a restart. Additionally, attackers can execute code on systems with Address Space Layout Randomization (ASLR) disabled or when the attacker can bypass ASLR. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
CVE-2026-42945 Critical 2026-05-13 Not applicable Exploited NGINX Plus and NGINX Open Source have a vulnerability in the ngx_http_rewrite_module module. This vulnerability exists when the rewrite directive is followed by a rewrite, if, or set directive and an unnamed Perl-Compatible Regular Expression (PCRE) capture (for example, $1, $2) with a replacement string that includes a question mark (?). An unauthenticated attacker along with conditions beyond its control can exploit this vulnerability by sending crafted HTTP requests. This may cause a heap buffer overflow in the NGINX worker process leading to a restart. Additionally, attackers can execute code on systems with Address Space Layout Randomization (ASLR) disabled or when the attacker can bypass ASLR.  Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
CVE-2026-42221 Critical 2026-05-04 Not applicable Working exploit published Nginx UI is a web user interface for the Nginx web server. From version 2.0.0 to before version 2.3.8, an unauthenticated network attacker can claim the initial administrator account on a fresh nginx-ui instance during the first-run setup window. The public /api/install endpoint is reachable without authentication, and the request-encryption flow only protects payload confidentiality in transit; it does not authenticate who is allowed to perform installation. A remote attacker who reaches the service before the legitimate operator can set the admin email, username, and password, causing permanent initial-instance takeover. This issue has been patched in version 2.3.8.
CVE-2026-33032 Critical 2026-03-30 Not applicable Exploited Nginx UI is a web user interface for the Nginx web server. In versions 2.3.5 and prior, the nginx-ui MCP (Model Context Protocol) integration exposes two HTTP endpoints: /mcp and /mcp_message. While /mcp requires both IP whitelisting and authentication (AuthRequired() middleware), the /mcp_message endpoint only applies IP whitelisting - and the default IP whitelist is empty, which the middleware treats as "allow all". This means any network attacker can invoke all MCP tools without authentication, including restarting nginx, creating/modifying/deleting nginx configuration files, and triggering automatic config reloads - achieving complete nginx service takeover. At time of publication, there are no publicly available patches.
CVE-2026-27654 High 2026-03-24 Not applicable Proof of concept only NGINX Open Source and NGINX Plus have a vulnerability in the ngx_http_dav_module module that might allow an attacker to trigger a buffer overflow to the NGINX worker process; this vulnerability may result in termination of the NGINX worker process or modification of source or destination file names outside the document root. This issue affects NGINX Open Source and NGINX Plus when the configuration file uses DAV module MOVE or COPY methods, prefix location (nonregular expression location configuration), and alias directives. The integrity impact is constrained because the NGINX worker process user has low privileges and does not have access to the entire system. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
CVE-2026-27944 Critical 2026-03-05 Not applicable Exploited Nginx UI is a web user interface for the Nginx web server. Prior to version 2.3.3, the /api/backup endpoint is accessible without authentication and discloses the encryption keys required to decrypt the backup in the X-Backup-Security response header. This allows an unauthenticated attacker to download a full system backup containing sensitive data (user credentials, session tokens, SSL private keys, Nginx configurations) and decrypt it immediately. This issue has been patched in version 2.3.3.
CVE-2024-46256 Critical 2024-09-27 Not applicable Proof of concept only A Command injection vulnerability in requestLetsEncryptSsl in NginxProxyManager 2.11.3 allows an attacker to RCE via Add Let's Encrypt Certificate.
CVE-2023-44487 High 2023-10-10 Mitigation candidate Exploited The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation can reset many streams quickly, as exploited in the wild in August through October 2023.
CVE-2021-23017 High 2021-06-01 Not applicable Working exploit published A security issue in nginx resolver was identified, which might allow an attacker who is able to forge UDP packets from the DNS server to cause 1-byte memory overwrite, resulting in worker process crash or potential other impact.
CVE-2019-20372 Medium 2020-01-09 Not applicable Proof of concept only NGINX before 1.17.7, with certain error_page configurations, allows HTTP request smuggling, as demonstrated by the ability of an attacker to read unauthorized web pages in environments where NGINX is being fronted by a load balancer.
CVE-2017-7529 High 2017-07-13 Not applicable Proof of concept only Nginx versions since 0.5.6 up to and including 1.13.2 are vulnerable to integer overflow vulnerability in nginx range filter module resulting into leak of potentially sensitive information triggered by specially crafted request.
CVE-2016-1247 High 2016-11-29 Not applicable Working exploit published The nginx package before 1.6.2-5+deb8u3 on Debian jessie, the nginx packages before 1.4.6-1ubuntu3.6 on Ubuntu 14.04 LTS, before 1.10.0-0ubuntu0.16.04.3 on Ubuntu 16.04 LTS, and before 1.10.1-0ubuntu1.1 on Ubuntu 16.10, and the nginx ebuild before 1.10.2-r3 on Gentoo allow local users with access to the web server user account to gain root privileges via a symlink attack on the error log.
CVE-2013-4547 High 2013-11-23 Not applicable Working exploit published nginx 0.8.41 through 1.4.3 and 1.5.x before 1.5.7 allows remote attackers to bypass intended restrictions via an unescaped space character in a URI.
CVE-2013-2028 High 2013-07-20 Not applicable Working exploit published The ngx_http_parse_chunked function in http/ngx_http_parse.c in nginx 1.3.9 through 1.4.0 allows remote attackers to cause a denial of service (crash) and execute arbitrary code via a chunked Transfer-Encoding request with a large chunk size, which triggers an integer signedness error and a stack-based buffer overflow.
CVE-2010-2266 Medium 2010-06-15 Not applicable Working exploit published nginx 0.8.36 allows remote attackers to cause a denial of service (crash) via certain encoded directory traversal sequences that trigger memory corruption, as demonstrated using the "%c0.%c0." sequence.
CVE-2010-2263 Medium 2010-06-15 Not applicable Working exploit published nginx 0.8 before 0.8.40 and 0.7 before 0.7.66, when running on Windows, allows remote attackers to obtain source code or unparsed content of arbitrary files under the web document root by appending ::$DATA to the URI.
CVE-2009-4487 Medium 2010-01-13 Not applicable Working exploit published nginx 0.7.64 writes data to a log file without sanitizing non-printable characters, which might allow remote attackers to modify a window's title, or possibly execute arbitrary commands or overwrite files, via an HTTP request containing an escape sequence for a terminal emulator.
CVE-2009-3898 Medium 2009-11-24 Not applicable Working exploit published Directory traversal vulnerability in src/http/modules/ngx_http_dav_module.c in nginx (aka Engine X) before 0.7.63, and 0.8.x before 0.8.17, allows remote authenticated users to create or overwrite arbitrary files via a .. (dot dot) in the Destination HTTP header for the WebDAV (1) COPY or (2) MOVE method.
CVE-2009-3555 Critical 2009-11-09 Not applicable Exploited The TLS protocol, and the SSL protocol 3.0 and possibly earlier, as used in Microsoft Internet Information Services (IIS) 7.0, mod_ssl in the Apache HTTP Server 2.2.14 and earlier, OpenSSL before 0.9.8l, GnuTLS 2.8.5 and earlier, Mozilla Network Security Services (NSS) 3.12.4 and earlier, multiple Cisco products, and other products, does not properly associate renegotiation handshakes with an existing connection, which allows man-in-the-middle attackers to insert data into HTTPS sessions, and possibly other types of sessions protected by TLS or SSL, by sending an unauthenticated request that is processed retroactively by a server in a post-renegotiation context, related to a "plaintext injection" attack, aka the "Project Mogul" issue.
CVE-2009-2629 High 2009-09-15 Not applicable Exploited Buffer underflow in src/http/ngx_http_parse.c in nginx 0.1.0 through 0.5.37, 0.6.x before 0.6.39, 0.7.x before 0.7.62, and 0.8.x before 0.8.15 allows remote attackers to execute arbitrary code via crafted HTTP requests.
