Prior to version 1.39.4, an unauthenticated user can trigger Lookyloo's \"report a capture\" email on demand (this is expected). The /json/<uuid>/report API endpoint (CaptureReport) is incorrectly passing the email and comment parameters, overwriting as_admin. When True, as_admin will trigger a search query on a MISP instance (if configured) and add a list of matching URLs in the email sent to the analyst (not the submitter, so there is no risk of leaking information) . It could potentially cause a DoS on the MISP instance. This issue has been patched in version 1.39.4.","state":0,"publishedAt":"2026-10-23T04:14:02.867+00:00","modifiedAt":"2026-10-23T21:05:41.736+00:00","affected":[{"ecosystem":"Vendor product","name":"lookyloo","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Lookyloo\",\n                    \"product\": \"lookyloo\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 1.39.4\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:N/SC:N/SI:N/SA:L","score":6.9,"severity":"MEDIUM"}],"references":["https://github.com/Lookyloo/lookyloo/security/advisories/GHSA-66gj-hmcp-5cfj","https://github.com/Lookyloo/lookyloo/pull/1330","https://github.com/Lookyloo/lookyloo/commit/d5b9a401998cd50b88e5d7425f82baac78d8f082","https://github.com/Lookyloo/lookyloo/releases/tag/v1.39.4"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-55835","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-55835","identifiers":["CVE-2026-55835"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
