PYSEC-2026-1718

Vulnerability from pysec - Published: 2026-07-07 11:45 - Updated: 2026-07-07 17:24
VLAI
Details

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
