GHSA-vr85-5pwx-c6gq: OMERO.web must check that the JSONP callback is a valid function
Background
There is currently no escaping or validation of the callback parameter that can be passed to various OMERO.web endpoints that have JSONP enabled. One such endpoint is /webclient/imgData/.... As we only really use these endpoints with jQuery’s own callback name generation [1] it is quite difficult or even impossible to exploit this in vanilla OMERO.web. However, these metadata endpoints are likely to be used by many plugins.
Impact
OMERO.web before 5.25.0
Patches
Users should upgrade to 5.26.0 or higher
Workarounds
None
