A flaw was found in hibernate-validator's 'isValid' method in the org.hibernate.validator.internal.constraintvalidators.hv.SafeHtmlValidator class, which can be bypassed by omitting the tag ending in a less-than character. Browsers may render an invalid html, allowing HTML injection or Cross-Site-Scripting (XSS) attacks.

A flaw was found in WildFly, where an attacker can see deployment names, endpoints, and any other data the trace payload may contain.

It was found in AMQ Online before 1.5.2 that injecting an invalid field to a user's AddressSpace configuration of the user namespace puts AMQ Online in an inconsistent state, where the AMQ Online components do not operate properly, such as the failure of provisioning and the failure of creating addresses, though this does not impact upon already existing messaging clients or brokers.

It was found that the AMQ Online console is vulnerable to a Cross-Site Request Forgery (CSRF) which is exploitable in cases where preflight checks are not instigated or bypassed. For example authorised users using an older browser with Adobe Flash are vulnerable when targeted by an attacker. This flaw affects all versions of AMQ-Online prior to 1.5.2 and Enmasse versions 0.31.0-rc1 up until but not including 0.32.2.
