Exploit for CVE-2026-63292

⚠️ CVE-2026-63292 — Apache HTTP Server Security Vulnerability...

httpd: httpd: Denial of Service via mod_rewrite lookahead

A use-after-free flaw was found in the modrewrite module of Apache HTTP Server when evaluating URL lookahead expressions that reference HTTP request headers, such as %LA-U:HTTP:.... A remote attacker may be able to trigger invalid memory access in a server using an affected rewrite configuration,...

httpd: Apache HTTP Server: mod_http2 use-after-free / wild write via shared session->bbtmp re-entrancy

A flaw was found in the modhttp2 module of Apache HTTP Server. A remote, unauthenticated attacker could exploit a use-after-free condition—where memory is accessed after being released—through re-entrant processing of shared session buffers. This flaw can allow an attacker to potentially execute...

httpd: httpd: mod_heartmonitor: Denial of Service via NULL pointer dereference

A flaw was found in the modheartmonitor module of the Apache HTTP Server. A remote, unauthenticated attacker can exploit a NULL pointer dereference vulnerability when the module is configured with a unicast listener. By sending specially crafted network traffic to the listening service, an attack...

httpd: httpd: Denial of Service via crafted HTTP response bodies in mod_proxy_html

A flaw was found in the modproxyhtml module of Apache HTTP Server. An attacker who controls or manipulates HTTP response bodies processed by the proxy can trigger an out-of-bounds memory write. This issue can cause the server process to crash, resulting in a Denial of Service DoS...

httpd: httpd: Information disclosure via session cookie leakage during internal redirects

A flaw was found in Apache HTTP Server's modsessioncookie module. When internal redirects alter the SessionCookieRemove configuration, the server may fail to strip the session cookie as expected. This issue can lead to information disclosure by inadvertently forwarding sensitive user session toke...

httpd: httpd: Information disclosure via direct request to the WebDAV state directory

A flaw was found in the moddavfs module of the Apache HTTP Server. A remote attacker can exploit this vulnerability by sending an HTTP GET request directly to the internal WebDAV Web Distributed Authoring and Versioning state directory. This allows unauthorized access to internal state files,...

httpd: httpd: Denial of Service via mod_dav shared lock memory calculation error

A flaw was found in the moddav module of the Apache HTTP Server. This vulnerability allows a Denial of Service DoS by crashing server child processes. An attacker with permission to create Web Distributed Authoring and Versioning WebDAV locks can trigger a memory calculation error during lock...

httpd: httpd: Information disclosure in mod_userdir via single-dot path equivalence

A flaw was found in Apache HTTP Server's moduserdir module. When configured with an absolute path without wildcards for the UserDir directive, the server fails to properly resolve single-dot directory '/./' path equivalence. A remote attacker can exploit this issue by submitting a crafted HTTP...

httpd: httpd: Denial of service via forged Authorization headers in mod_auth_digest

A flaw was found in the modauthdigest module of the Apache HTTP Server. When Digest authentication is configured with nonce-count checking enabled, missing authentication checks allow an unauthenticated remote attacker to submit forged HTTP Authorization headers. This flaw can lead to a Denial of...

httpd: httpd: HTTP response smuggling via crafted Transfer-Encoding response in mod_proxy_uwsgi

A flaw was found in the modproxyuwsgi module of Apache HTTP Server. This issue allows HTTP response smuggling when the server processes a crafted uWSGI response containing a Transfer-Encoding header. A remote attacker can exploit this vulnerability to desynchronize HTTP communications, potentiall...

httpd: httpd: Authentication bypass via credential replay in mod_auth_digest

A flaw was found in the modauthdigest module of the Apache HTTP Server. This vulnerability allows an attacker positioned on the network to bypass authentication by replaying previously intercepted user credentials. When the server is configured with a nonce a single-use security token lifetime of...

httpd: httpd: Denial of Service via charset conversion failure in mod_xml2enc

A flaw was found in the modxml2enc module of the Apache HTTP Server. An untrusted backend server can cause a Denial of Service DoS by returning a crafted response with a character set whose conversion partially succeeds and then fails. Processing this response triggers an invalid memory access nu...

httpd: httpd: arbitrary code execution via incorrect handler assignment during internal CGI redirects

A flaw was found in Apache HTTP Server. An attacker could achieve unintended code execution when an internal redirect generated by a Common Gateway Interface CGI program points to a non-executable file. If the target file resides in a directory configured for CGI execution and lacks a file...

httpd: Apache HTTP Server: mod_ssl SSLRequire allows .htaccess ap_expr file-function

A flaw was found in the modssl module of Apache HTTP Server. The SSLRequire directive does not properly restrict file-related expression functions in .htaccess files. An attacker who can write an .htaccess file in a directory where SSLRequire is permitted could use these functions to read files...

CVE-2026-47360

A flaw was found in Apache HTTP Server's modsessioncookie module. When internal redirects alter the SessionCookieRemove configuration, the server may fail to strip the session cookie as expected. This issue can lead to information disclosure by inadvertently forwarding sensitive user session toke...

CVE-2026-56449

A flaw was found in the modproxyhtml module of Apache HTTP Server. An attacker who controls or manipulates HTTP response bodies processed by the proxy can trigger an out-of-bounds memory write. This issue can cause the server process to crash, resulting in a Denial of Service DoS. Mitigation...

CVE-2026-48005

A flaw was found in the modauthdigest module of the Apache HTTP Server. When Digest authentication is configured with nonce-count checking enabled, missing authentication checks allow an unauthenticated remote attacker to submit forged HTTP Authorization headers. This flaw can lead to a Denial of...

CVE-2026-42356

A flaw was found in Apache HTTP Server. An attacker could achieve unintended code execution when an internal redirect generated by a Common Gateway Interface CGI program points to a non-executable file. If the target file resides in a directory configured for CGI execution and lacks a file...

Sonicwall - Pre-Authentication Arbitrary File Read

Improper escaping of output in modrewrite 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...
