CVE-2026-18855 is a critical arbitrary file deletion vulnerability in the Link Library plugin for WordPress affecting all versions up to and including 7.9.4. The flaw is caused by insufficient file path validation in the ll_delete_link_fields function, allowing attacker-controlled path input to reach file deletion logic without being properly restricted to an intended directory or safe file set. Under the required conditions, an unauthenticated attacker can submit a malicious link that references a chosen local file path and later cause that file to be deleted when the submitted link is permanently removed. Because deletion of security-sensitive application files can destabilize the site or trigger reinstallation and reconfiguration flows, the issue can escalate beyond file loss and may lead to remote code execution in some scenarios.
