CVE-2024-4704

The Contact Form 7 plugin for WordPress is vulnerable to Open Redirect in all versions up to, and including, 5.9.4. This is due to insufficient validation on the redirect url supplied via accessing the contact form with a spoofed page. This makes it possible for unauthenticated attackers to redirect site users to potentially malicious sites if they can successfully trick them into performing an action.

CVE-2023-6449

The Contact Form 7 plugin for WordPress is vulnerable to arbitrary file uploads due to insufficient file type validation in the 'validate' function and insufficient blocklisting on the 'wpcf7_antiscript_file_name' function in versions up to, and including, 5.8.3. This makes it possible for authenticated attackers with editor-level capabilities or above to upload arbitrary files on the affected site's server, but due to the htaccess configuration, remote code cannot be executed in most cases. By default, the file will be deleted from the server immediately. However, in some cases, other plugins may make it possible for the file to live on the server longer. This can make remote code execution possible when combined with another vulnerability, such as local file inclusion.

CVE-2020-35489

The Contact Form 7 plugin for WordPress is vulnerable to arbitrary file uploads in versions up to 5.3.2. This is due to the fact that the plugin allows filenames to contain special characters which may make extension filter evasion possible on certain configurations. Our team was not able to reproduce this issue which leads us to believe there is a high attack complexity or special configuration requirement.

CVE-2018-20979

According to the official release: "A privilege escalation vulnerability has been found in Contact Form 7 5.0.3 and older versions. Utilizing this vulnerability, a logged-in user in the Contributor role can potentially edit contact forms, which only Administrator and Editor-role users are allowed to access by default. This issue has been reported by Simon Scannell from RIPS Technologies. To minimize damage from possible attacks utilizing those vulnerabilities, Contact Form 7 5.0.4 and higher will restrict the local file attachment feature. More particularly, you will no longer be able to specify an absolute file path that refers to a file placed outside the wp-content directory. You can still specify files inside the wp-content directory with relative or absolute file paths, so all you need to change is the location of the attachment files." According to the changelog: "Specifies the capability_type argument explicitly in the register_post_type() call to fix the privilege escalation vulnerability issue."

The Contact Form 7 plugin for WordPress is vulnerable to Order Replay in all versions up to, and including, 6.0.5 via the 'wpcf7_stripe_skip_spam_check' function due to insufficient validation on a user controlled key.
