Audit log disclosure via unauthenticated ONVIF endpoints
Published Jul 27, 2026 · Updated Jul 27, 2026
Information disclosure in Honeywell 35 Series IP Cameras HC5.26.1.14.20260207 and earlier allows remote attackers to read audit logs. Two ONVIF HTTP endpoints omit authentication checks and return the full administrative audit log that other ONVIF log methods protect. Network access to an affected camera is sufficient; the documented impact is disclosure of administrator-only log data, not log modification or service interruption.
