| CVE-2004-0748 | 2 Apache, Redhat | 2 Http Server, Enterprise Linux | 2026-04-16 | 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-2004-0751 | 2 Apache, Redhat | 2 Http Server, Enterprise Linux | 2026-04-16 | N/A |
| The char_buffer_read function in the mod_ssl module for Apache 2.x, when using reverse proxying to an SSL server, allows remote attackers to cause a denial of service (segmentation fault). | ||||
| CVE-2004-0940 | 7 Apache, Hp, Openpkg and 4 more | 9 Http Server, Hp-ux, Openpkg and 6 more | 2026-04-16 | 7.8 High |
| Buffer overflow in the get_tag function in mod_include for Apache 1.3.x to 1.3.32 allows local users who can create SSI documents to execute arbitrary code as the apache user via SSI (XSSI) documents that trigger a length calculation error. | ||||
| CVE-2004-1082 | 8 Apache, Apple, Avaya and 5 more | 14 Http Server, Apache Mod Digest Apple, Communication Manager and 11 more | 2026-04-16 | N/A |
| mod_digest_apple for Apache 1.3.31 and 1.3.32 on Mac OS X Server does not properly verify the nonce of a client response, which allows remote attackers to replay credentials. | ||||
| CVE-2004-2343 | 1 Apache | 1 Http Server | 2026-04-16 | N/A |
| Apache HTTP Server 2.0.47 and earlier allows local users to bypass .htaccess file restrictions, as specified in httpd.conf with directives such as Deny From All, by using an ErrorDocument directive. NOTE: the vendor has disputed this issue, since the .htaccess mechanism is only intended to restrict external web access, and a local user already has the privileges to perform the same operations without using ErrorDocument | ||||
| CVE-2005-1268 | 3 Apache, Debian, Redhat | 6 Http Server, Debian Linux, Enterprise Linux and 3 more | 2026-04-16 | N/A |
| Off-by-one error in the mod_ssl Certificate Revocation List (CRL) verification callback in Apache, when configured to use a CRL, allows remote attackers to cause a denial of service (child process crash) via a CRL that causes a buffer overflow of one null byte. | ||||
| CVE-2005-2088 | 3 Apache, Debian, Redhat | 3 Http Server, Debian Linux, Enterprise Linux | 2026-04-16 | N/A |
| The Apache HTTP server before 1.3.34, and 2.0.x before 2.0.55, when acting as an HTTP proxy, allows remote attackers to poison the web cache, bypass web application firewall protection, and conduct XSS attacks via an HTTP request with both a "Transfer-Encoding: chunked" header and a Content-Length header, which causes Apache to incorrectly handle and forward the body of the request in a way that causes the receiving server to process it as a separate HTTP request, aka "HTTP Request Smuggling." | ||||
| CVE-2002-0840 | 3 Apache, Oracle, Redhat | 9 Http Server, Application Server, Database Server and 6 more | 2026-04-16 | N/A |
| Cross-site scripting (XSS) vulnerability in the default error page of Apache 2.0 before 2.0.43, and 1.3.x up to 1.3.26, when UseCanonicalName is "Off" and support for wildcard DNS is present, allows remote attackers to execute script as other web page visitors via the Host: header, a different vulnerability than CAN-2002-1157. | ||||
| CVE-2004-0263 | 2 Apache, Ibm | 2 Http Server, Http Server | 2026-04-16 | N/A |
| PHP 4.3.4 and earlier in Apache 1.x and 2.x (mod_php) can leak global variables between virtual hosts that are handled by the same Apache child process but have different settings, which could allow remote attackers to obtain sensitive information. | ||||
| CVE-2006-3747 | 3 Apache, Canonical, Debian | 3 Http Server, Ubuntu Linux, Debian Linux | 2026-04-16 | N/A |
| Off-by-one error in the ldap scheme handling in the Rewrite module (mod_rewrite) in Apache 1.3 from 1.3.28, 2.0.46 and other versions before 2.0.59, and 2.2, when RewriteEngine is enabled, allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via crafted URLs that are not properly handled using certain rewrite rules. | ||||
| CVE-2006-3918 | 4 Apache, Canonical, Debian and 1 more | 9 Http Server, Ubuntu Linux, Debian Linux and 6 more | 2026-04-16 | 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-2025-23048 | 2 Apache, Apache Software Foundation | 2 Http Server, Apache Http Server | 2026-02-26 | 9.1 Critical |
| In some mod_ssl configurations on Apache HTTP Server 2.4.35 through to 2.4.63, an access control bypass by trusted clients is possible using TLS 1.3 session resumption. Configurations are affected when mod_ssl is configured for multiple virtual hosts, with each restricted to a different set of trusted client certificates (for example with a different SSLCACertificateFile/Path setting). In such a case, a client trusted to access one virtual host may be able to access another virtual host, if SSLStrictSNIVHostCheck is not enabled in either virtual host. | ||||
| CVE-2025-58098 | 1 Apache | 1 Http Server | 2026-02-26 | 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-2021-41773 | 4 Apache, Fedoraproject, Netapp and 1 more | 4 Http Server, Fedora, Cloud Backup and 1 more | 2026-02-17 | 7.5 High |
| 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 | 2 Apache, Redhat | 8 Http Server, Enterprise Linux, Jboss Core Services and 5 more | 2025-12-18 | 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 | 4 Apache, Fedoraproject, Netapp and 1 more | 6 Http Server, Fedora, Clustered Data Ontap and 3 more | 2025-12-18 | 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 | 2 Apache, Microsoft | 2 Http Server, Windows | 2025-12-10 | 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 | 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 | 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 | 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. | ||||
