{"id":"CVE-2026-57443","summary":"SCBE-AETHERMOORE Unauthenticated AetherBrowser Ops API Exposes Operator Email Digests","details":"SCBE-AETHERMOORE is a geometric AI governance and evaluation framework. Starting in version 4.0.2 and prior to version 4.2.1, the AetherBrowser API server (`scripts/aetherbrowser/api_server.py`) exposes the `POST /api/ops/check-email` endpoint without any authentication. Any remote attacker can call this endpoint and trigger execution of the `email_reader.py` subprocess, which connects to configured ProtonMail or Gmail accounts via IMAP and returns email metadata (sender, subject, body snippet) in the JSON response. The server binds to `0.0.0.0:8100` by default with CORS set to `allow_origins=[\"*\"]`, making it reachable from any network or browser origin. Version 4.2.1 patches the issue.","aliases":["GHSA-q986-4x7x-gx39"],"modified":"2026-09-27T03:47:33.920407391Z","published":"2026-09-25T20:37:52.116Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/57xxx/CVE-2026-57443.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-306"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/57xxx/CVE-2026-57443.json"},{"type":"ADVISORY","url":"https://github.com/issdandavis/SCBE-AETHERMOORE/security/advisories/GHSA-q986-4x7x-gx39"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-57443"},{"type":"FIX","url":"https://github.com/issdandavis/SCBE-AETHERMOORE/commit/ca833795e01eab060e92572e5f667c0c136b8c1e"},{"type":"FIX","url":"https://github.com/issdandavis/SCBE-AETHERMOORE/commit/de7779b722c501dbcf4eae95dd51bb3984506fb1"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/issdandavis/scbe-aethermoore","events":[{"introduced":"0b4a41b17afe2d5afb6ad1998af856f7494fcaba"},{"fixed":"ca833795e01eab060e92572e5f667c0c136b8c1e"},{"fixed":"de7779b722c501dbcf4eae95dd51bb3984506fb1"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"4.0.2"},{"fixed":"4.2.1"}]}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-57443.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"}]}
