apache2 vulnerabilities
Details

It was discovered that the Apache HTTP Server incorrectly handled failed ACME certificate renewals. This could result in renewal attempts to be repeated without delays, possibly leading to a denial of service. (CVE-2025-55753)

Anthony Parfenov discovered that the Apache HTTP Server would pass the query string to cmd directives when configured with Server Side Includes (SSI) enabled and mod_cgid. An attacker could possibly use this issue to execute arbitrary code. (CVE-2025-58098)

Mattias Åsander discovered that the Apache HTTP Server incorrectly neutralized certain environment variables. This could result in unexpectedly superseding variables calculated by the server for CGI programs. (CVE-2025-65082)

Mattias Åsander discovered that the Apache HTTP Server incorrectly handled AllowOverride FileInfo configurations when using mod_userdir with suexec. An attacker with access to use the RequestHeader directive in htaccess can cause some CGI scripts to run under an unexpected userid. (CVE-2025-66200)

This could result in renewal attempts to be\nrepeated without delays, possibly leading to a denial of service.\n(CVE-2025-55753)\n\nAnthony Parfenov discovered that the Apache HTTP Server would pass the\nquery string to cmd directives when configured with Server Side Includes\n(SSI) enabled and mod_cgid. An attacker could possibly use this issue to\nexecute arbitrary code. (CVE-2025-58098)\n\nMattias \u00c5sander discovered that the Apache HTTP Server incorrectly\nneutralized certain environment variables. This could result in\nunexpectedly superseding variables calculated by the server for CGI\nprograms.
