In previous versions of Puppet Agent it was possible to install a module with world writable permissions. Puppet Agent 5.3.4 and 1.10.10 included a fix to this vulnerability.

A deserialization flaw was discovered in the jackson-databind in versions before 2.8.10 and 2.9.1, which could allow an unauthenticated user to perform code execution by sending the maliciously crafted input to the readValue method of the ObjectMapper. This issue extends the previous flaw CVE-2017-7525 by blacklisting more classes that could be used maliciously.

In Hibernate Validator 5.2.x before 5.2.5 final, 5.3.x, and 5.4.x, it was found that when the security manager's reflective permissions, which allows it to access the private members of the class, are granted to Hibernate Validator, a potential privilege escalation can occur. By allowing the calling code to access those private members without the permission an attacker may be able to validate an invalid instance and access the private member value via ConstraintViolation#getInvalidValue().

An attacker submitting facts to the Foreman server containing HTML can cause a stored XSS on certain pages: (1) Facts page, when clicking on the "chart" button and hovering over the chart; (2) Trends page, when checking the graph for a trend based on a such fact; (3) Statistics page, for facts that are aggregated on this page.
