Emlog is an open source website building system. Versions 2.5.13 and prior have a deserialization vulnerability. A user who creates a carefully crafted nickname can cause "str_replace" to replace the value of "name_orig" with empty, causing deserialization to fail and return "false". Commit 9643250802188b791419e3c2188577073256a8a2 fixes the issue.
