eZ Systems eZ Publish version 5.4.0 to 5.4.9, and 5.3.12 and older, is vulnerable to an XSS issue in the search module, resulting in a risk of attackers injecting scripts which may e.g. steal authentication credentials.
eZ publish before 3.8.9, and 3.9 before 3.9.3, does not properly check permissions on module views that lack a policy function, which has unknown impact and attack vectors, as demonstrated by a vulnerability in the discount functionality in the shop module.
The tipafriend function in eZ publish before 3.8.9, and 3.9 before 3.9.3, does not limit access by anonymous users, which allows remote attackers to conduct spam attacks.
