An improper privilege management issue exists in the `mod ssl` module. The flaw occurs when using `SSLRequire` in conjunction with file-related expressions via `ap expr` file functions, which can lead to improper privilege escalation without requiring authentication.

An issue exists where cookie input is handled incorrectly, specifically involving a stack buffer underflow in the `read cookie()` function. This was introduced as a regression in a previous fix. A local attacker could exploit this to cause the system to crash, leading to a denial of service, or to execute arbitrary code.

This issue occurs when the plugin fails to escape user-supplied input before reflecting it in the contact form output during validation errors. This leads to Reflected Cross-Site Scripting (XSS), a condition where a malicious script is reflected off a web application to the user's browser. Unauthenticated attackers can exploit this by using a crafted link or cross-site form submission to target site visitors.
