Lychee is a free photo-management tool. Prior to 5.0.2, Lychee is vulnerable to an SQL injection on any binding when using mysql/mariadb. This injection is only active for users with the .env
settings set to DBLOGSQL=true and DBLOGSQL_EXPLAIN=true. The defaults settings of Lychee are safe. The patch is provided on version 5.0.2. To work around this issue, disable SQL EXPLAIN logging.
