This issue affects Apache HTTP Server: from 2.4.0 through 2.4.68.(CVE-2026-57941)
Internal state files accessible to external parties in mod_dav_fs in Apache Software Foundation Apache HTTP Server before 2.4.69 on all platforms allows a remote client to read WebDAV dead properties of resources it cannot author via a GET request for the .DAV state directory
This issue affects Apache HTTP Server: from 2.4.0 through 2.4.68.(CVE-2026-58415)
Out-of-bounds Write vulnerability in Apache HTTP Server on Windows while processing paths with 8.3 names that may grow when expanded.
This issue affects Apache HTTP Server: from 2.4.0 through 2.4.68.(CVE-2026-59685)
Improper Privilege Management vulnerability in Apache HTTP Server's mod_ssl via SSLRequire and file-related expressions.
This issue affects Apache HTTP Server: from 2.4.0 through 2.4.68.(CVE-2026-59797)
Improper validation of FTP PASV reply address in mod_proxy_ftp in Apache Software Foundation Apache HTTP Server through 2.4.68 on all platforms allows, in forward proxy configurations, an untrusted FTP server to cause the proxy to open a data connection to an arbitrary third-party host via a crafted PASV response.
Users are recommended to upgrade to version 2.4.69, which fixes this issue.(CVE-2026-63045)
Stack-based buffer overflow in mod_vhost_alias in Apache Software Foundation Apache HTTP Server through 2.4.68 on all platforms allows a remote client to cause a denial of service or potentially execute arbitrary code via an HTTP request with a Host header exceeding 8192 bytes when VirtualDocumentRoot uses a hostname format specifier and LimitRequestFieldSize is raised above the default.
Users are recommended to upgrade to version 2.4.69, which fixes this issue.(CVE-2026-63292)
A NULL pointer dereference in mod_xml2enc in Apache Software Foundation Apache HTTP Server before 2.4.69 on all platforms allows an untrusted backend server to cause a denial of service via a proxied response with a charset whose conversion partially succeeds then fails.
Users are recommended to upgrade to version 2.4.69, which fixes this issue.(CVE-2026-63686)
Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') response smuggling vulnerability in Apache HTTP Server via mod_proxy_uwsgi and a crafted uwsgi response with Transfer-Encoding.
This issue affects Apache HTTP Server: from 2.4.30 through 2.4.68.(CVE-2026-63718)
Path equivalence: '/./' (single dot directory) vulnerability in Apache HTTP Server's mod_userdir module when configured with absolute non-wildcard UserDir directive (the 2nd form in https://httpd.apache.org/docs/2.4/mod/mod_userdir.html#userdir)
This issue affects Apache HTTP Server: from 2.4.0 through 2.4.68.(CVE-2026-79768)
Integer overflow in mod_dav_fs in Apache HTTP Server through 2.4.68 allows an authenticated WebDAV client with write access to crash worker processes and persistently corrupt a directory's property database via PROPPATCH requests declaring many XML namespaces.(CVE-2026-93546)
