CVE-2020-8547 is a critical authentication bypass vulnerability affecting phpList version 3.5.0. It arises from a type juggling flaw where the application uses loose comparison (==) instead of strict comparison (===) for password hashes, allowing an attacker to bypass login if a hash begins with "0e" followed by only numerical characters. With a CVSS score of 9.8, this vulnerability is easily exploitable over the network with low complexity and no user interaction, potentially leading to full compromise of confidentiality, integrity, and availability. While not listed in CISA's KEV catalog, an exploit is publicly available on ExploitDB, though there is minimal community discussion or media coverage surrounding this CVE.
