Unauthenticated PHP Object Injection affects the Everest Forms WordPress plugin (wpeverest) in all versions up to and including 3.6.0, allowing remote attackers to pass attacker-controlled serialized data into a PHP unserialize() call. If a suitable POP (property-oriented programming) gadget chain is present in the plugin, an installed theme, or WordPress core, this can escalate to arbitrary file operations, SQL injection, or remote code execution. Reported by Patchstack; no public exploit identified at time of analysis, and no EPSS or KEV signal was provided.
Information disclosure in the Everest Forms WordPress plugin before 3.5.0 allows unauthenticated remote attackers to download other users' form submissions. The plugin generates temporary CSV files during email-notification processing but fails to reliably delete them, leaving them publicly accessible in the wp-content uploads directory under predictable, enumerable filenames. Publicly available exploit code exists and the flaw is automatable per CISA SSVC, though EPSS remains low at 0.14%; not listed in CISA KEV.
Unauthenticated remote attackers can completely bypass access controls on Everest Forms REST API endpoints in all plugin versions before 3.5.0, enabling them to read onboarding status data, modify plugin settings, and send emails from the WordPress site to arbitrary addresses. The flaw arises because the capability check is conditioned on an attacker-controllable HTTP request header - omitting or altering that header disables the authorization gate entirely. A publicly available proof-of-concept exploit exists, and SSVC assessment confirms the attack is automatable; however, this vulnerability is not in CISA KEV, and EPSS sits at 0.14%, suggesting limited observed exploitation despite the low barrier to entry.
The Everest Forms (Pro) WordPress plugin versions up to 1.9.4 contain an arbitrary file deletion vulnerability in the delete_entry_files() function due to insufficient path validation (CWE-36). Unauthenticated attackers can delete arbitrary files on the server by tricking an administrator into deleting a form entry, potentially leading to remote code execution through deletion of critical files like wp-config.php. This is a high-severity vulnerability (CVSS 7.5) that requires social engineering or admin interaction but can completely compromise WordPress installations.
