|---|---|---|---|---|---|
| CVE-1999-1199 | 1 Apache | 1 Http Server | 2026-04-16 | 10.0 HIGH | N/A |
| Apache WWW server 1.3.1 and earlier allows remote attackers to cause a denial of service (resource exhaustion) via a large number of MIME headers with the same name, aka the "sioux" vulnerability. | |||||
| CVE-2005-1344 | 1 Apache | 1 Http Server | 2026-04-16 | 7.5 HIGH | N/A |
| Buffer overflow in htdigest in Apache 2.0.52 may allow attackers to execute arbitrary code via a long realm argument. NOTE: since htdigest is normally only locally accessible and not setuid or setgid, there are few attack vectors which would lead to an escalation of privileges, unless htdigest is executed from a CGI program. Therefore this may not be a vulnerability. | |||||
| CVE-2004-0809 | 8 Apache, Debian, Gentoo and 5 more | 12 Http Server, Debian Linux, Linux and 9 more | 2026-04-16 | 5.0 MEDIUM | N/A |
| The mod_dav module in Apache 2.0.50 and earlier allows remote attackers to cause a denial of service (child process crash) via a certain sequence of LOCK requests for a location that allows WebDAV authoring access. | |||||
| CVE-1999-1412 | 2 Apache, Apple | 2 Http Server, Macos | 2026-04-16 | 5.0 MEDIUM | N/A |
| A possible interaction between Apple MacOS X release 1.0 and Apache HTTP server allows remote attackers to cause a denial of service (crash) via a flood of HTTP GET requests to CGI programs, which generates a large number of processes. | |||||
| CVE-2004-0173 | 1 Apache | 1 Http Server | 2026-04-16 | 5.0 MEDIUM | N/A |
| Directory traversal vulnerability in Apache 1.3.29 and earlier, and Apache 2.0.48 and earlier, when running on Cygwin, allows remote attackers to read arbitrary files via a URL containing "..%5C" (dot dot encoded backslash) sequences. | |||||
| CVE-2002-1850 | 1 Apache | 1 Http Server | 2026-04-16 | 5.0 MEDIUM | 7.5 HIGH |
| mod_cgi in Apache 2.0.39 and 2.0.40 allows local users and possibly remote attackers to cause a denial of service (hang and memory consumption) by causing a CGI script to send a large amount of data to stderr, which results in a read/write deadlock between httpd and the CGI script. | |||||
| CVE-2006-3918 | 4 Apache, Canonical, Debian and 1 more | 5 Http Server, Ubuntu Linux, Debian Linux and 2 more | 2026-04-16 | 4.3 MEDIUM | N/A |
| http_protocol.c in (1) IBM HTTP Server 6.0 before 6.0.2.13 and 6.1 before 6.1.0.1, and (2) Apache HTTP Server 1.3 before 1.3.35, 2.0 before 2.0.58, and 2.2 before 2.2.2, does not sanitize the Expect header from an HTTP request when it is reflected back in an error message, which might allow cross-site scripting (XSS) style attacks using web client components that can send arbitrary headers in requests, as demonstrated using a Flash SWF file. | |||||
| CVE-2004-0748 | 1 Apache | 1 Http Server | 2026-04-16 | 5.0 MEDIUM | N/A |
| mod_ssl in Apache 2.0.50 and earlier allows remote attackers to cause a denial of service (CPU consumption) by aborting an SSL connection in a way that causes an Apache child process to enter an infinite loop. | |||||
| CVE-2021-41773 | 4 Apache, Fedoraproject, Netapp and 1 more | 4 Http Server, Fedora, Cloud Backup and 1 more | 2026-02-17 | 4.3 MEDIUM | 9.8 CRITICAL |
| A flaw was found in a change made to path normalization in Apache HTTP Server 2.4.49. An attacker could use a path traversal attack to map URLs to files outside the directories configured by Alias-like directives. If files outside of these directories are not protected by the usual default configuration "require all denied", these requests can succeed. If CGI scripts are also enabled for these aliased pathes, this could allow for remote code execution. This issue is known to be exploited in the wild. This issue only affects Apache 2.4.49 and not earlier versions. The fix in Apache HTTP Server 2.4.50 was found to be incomplete, see CVE-2021-42013. | |||||
| CVE-2023-25690 | 1 Apache | 1 Http Server | 2025-12-18 | 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-2022-28615 | 3 Apache, Fedoraproject, Netapp | 3 Http Server, Fedora, Clustered Data Ontap | 2025-12-18 | 6.4 MEDIUM | 9.1 CRITICAL |
| Apache HTTP Server 2.4.53 and earlier may crash or disclose information due to a read beyond bounds in ap_strcmp_match() when provided with an extremely large input buffer. While no code distributed with the server can be coerced into such a call, third-party modules or lua scripts that use ap_strcmp_match() may hypothetically be affected. | |||||
| CVE-2025-59775 | 1 Apache | 1 Http Server | 2025-12-10 | N/A | 7.5 HIGH |
| Server-Side Request Forgery (SSRF) vulnerability in Apache HTTP Server on Windows with AllowEncodedSlashes On and MergeSlashes Off allows to potentially leak NTLM hashes to a malicious server via SSRF and malicious requests or content Users are recommended to upgrade to version 2.4.66, which fixes the issue. | |||||
| CVE-2025-65082 | 1 Apache | 1 Http Server | 2025-12-10 | N/A | 6.5 MEDIUM |
| Improper Neutralization of Escape, Meta, or Control Sequences vulnerability in Apache HTTP Server through environment variables set via the Apache configuration unexpectedly superseding variables calculated by the server for CGI programs. This issue affects Apache HTTP Server from 2.4.0 through 2.4.65. Users are recommended to upgrade to version 2.4.66 which fixes the issue. | |||||
| CVE-2025-66200 | 1 Apache | 1 Http Server | 2025-12-10 | N/A | 5.4 MEDIUM |
| mod_userdir+suexec bypass via AllowOverride FileInfo vulnerability in Apache HTTP Server. Users with access to use the RequestHeader directive in htaccess can cause some CGI scripts to run under an unexpected userid. This issue affects Apache HTTP Server: from 2.4.7 through 2.4.65. Users are recommended to upgrade to version 2.4.66, which fixes the issue. | |||||
| CVE-2025-55753 | 1 Apache | 1 Http Server | 2025-12-10 | N/A | 7.5 HIGH |
| An integer overflow in the case of failed ACME certificate renewal leads, after a number of failures (~30 days in default configurations), to the backoff timer becoming 0. Attempts to renew the certificate then are repeated without delays until it succeeds. This issue affects Apache HTTP Server: from 2.4.30 before 2.4.66. Users are recommended to upgrade to version 2.4.66, which fixes the issue. | |||||
| CVE-2025-58098 | 1 Apache | 1 Http Server | 2025-12-08 | N/A | 8.3 HIGH |
| Apache HTTP Server 2.4.65 and earlier with Server Side Includes (SSI) enabled and mod_cgid (but not mod_cgi) passes the shell-escaped query string to #exec cmd="..." directives. This issue affects Apache HTTP Server before 2.4.66. Users are recommended to upgrade to version 2.4.66, which fixes the issue. | |||||
| CVE-2024-38475 | 3 Apache, Netapp, Sonicwall | 12 Http Server, Ontap 9, Sma 200 and 9 more | 2025-11-17 | N/A | 9.1 CRITICAL |
| Improper escaping of output in mod_rewrite in Apache HTTP Server 2.4.59 and earlier allows an attacker to map URLs to filesystem locations that are permitted to be served by the server but are not intentionally/directly reachable by any URL, resulting in code execution or source code disclosure. Substitutions in server context that use a backreferences or variables as the first segment of the substitution are affected. Some unsafe RewiteRules will be broken by this change and the rewrite flag "UnsafePrefixStat" can be used to opt back in once ensuring the substitution is appropriately constrained. | |||||
| CVE-2024-36387 | 2 Apache, Netapp | 2 Http Server, Ontap | 2025-11-06 | N/A | 5.4 MEDIUM |
| Serving WebSocket protocol upgrades over a HTTP/2 connection could result in a Null Pointer dereference, leading to a crash of the server process, degrading performance. | |||||
