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","published":"2024-05-21T12:33:02.639Z","modified":"2026-08-12T03:51:26.201444001Z","cvss":{"score":6.1,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"omero-web","fixedVersion":"5.26.0"}],"fix":{"url":"https://github.com/ome/omero-web/commit/d41207cbb82afc56ea79e84db532608aa24ab4aa","label":"ome/omero-web@d41207c"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/35xxx/CVE-2024-35180.json"},{"type":"ADVISORY","url":"https://github.com/ome/omero-web/security/advisories/GHSA-vr85-5pwx-c6gq"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-35180"},{"type":"FIX","url":"https://github.com/ome/omero-web/commit/d41207cbb82afc56ea79e84db532608aa24ab4aa"},{"type":"PACKAGE","url":"https://github.com/ome/omero-web"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:26.201444001Z"}}
