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.\n\n[^1]: https://learn.jquery.com/ajax/working-with-jsonp/\n\n### Impact\nOMERO.web before 5.25.0\n\n### Patches\nUsers should upgrade to 5.26.0 or higher\n### Workarounds\n\nNone\n\n### References\n* https://stackoverflow.com/questions/2777021/do-i-need-to-sanitize-the-callback-parameter-from-a-jsonp-call\n* https://stackoverflow.com/questions/1661197/what-characters-are-valid-for-javascript-variable-names\n\nFor more information\nIf you have any questions or comments about this advisory:\n\nOpen an issue in [omero-web](https://github.com/ome/omero-web)\nEmail us at [security@openmicroscopy.org](mailto:security@openmicroscopy.org)\n\n\n## Affected packages\n\n- `omero-web < 5.26.0`\n\n## Remediation\n\nUpgrade to a patched release:\n\n- `omero-web 5.26.0`","depth":"sunlit","depthScore":34,"depthScoreParts":{"impact":33.6,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
