KeePass through 2.53 (in a default installation) allows an attacker, who has write access to the XML configuration file, to obtain the cleartext passwords by adding an export trigger. NOTE: the vendor's position is that the password database is not intended to be secure against an attacker who has that level of access to the local PC.
The automatic update feature in KeePass 2.33 and earlier allows man-in-the-middle attackers to execute arbitrary code by spoofing the version check response and supplying a crafted update.
Untrusted search path vulnerability in KeePass Password Safe before 1.18 allows local users to gain privileges via a Trojan horse DLL in the current working directory, as demonstrated by a directory that contains a .kdb file. NOTE: some of these details are obtained from third party information.
