{"id":"CVE-2026-55835","published":"2026-10-23T05:17:15.543","lastModified":"2026-10-23T21:17:24.103","description":"Lookyloo is a web interface that allows users to capture a website page and then display a tree of domains that call each other. 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.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-233"],"vendors":[],"products":[],"references":[{"url":"https://github.com/Lookyloo/lookyloo/commit/d5b9a401998cd50b88e5d7425f82baac78d8f082","tags":[]},{"url":"https://github.com/Lookyloo/lookyloo/pull/1330","tags":[]},{"url":"https://github.com/Lookyloo/lookyloo/releases/tag/v1.39.4","tags":[]},{"url":"https://github.com/Lookyloo/lookyloo/security/advisories/GHSA-66gj-hmcp-5cfj","tags":[]}],"exploitRefs":[{"url":"https://github.com/Lookyloo/lookyloo/commit/d5b9a401998cd50b88e5d7425f82baac78d8f082","tags":[]},{"url":"https://github.com/Lookyloo/lookyloo/pull/1330","tags":[]},{"url":"https://github.com/Lookyloo/lookyloo/releases/tag/v1.39.4","tags":[]},{"url":"https://github.com/Lookyloo/lookyloo/security/advisories/GHSA-66gj-hmcp-5cfj","tags":[]}],"hasPoc":true,"ai":null}
