FrankenPHP before 1.13.2 contains an information disclosure vulnerability that allows later clients to read earlier clients' libxml errors because worker mode never resets LIBXML(error list) between requests. Attackers sending requests to the same worker thread can call libxml get errors() or libxml get last error() to obtain other clients' parsed-document fragments and server filesystem paths.
