CVE-2023-3947
The Video Conferencing with Zoom plugin for WordPress is vulnerable to Sensitive Information Exposure due to hardcoded encryption key on the 'vczapi_encrypt_decrypt' function in versions up to, and including, 4.2.1.
Does this matter?
Lower severity and a low EPSS score (0.40%). Track it; it rarely justifies an emergency change on its own.
