Last updated November 8, 2026
Document type: local CVE candidate assessment, not a published CVE Record. CVE ID: unassigned. Product scope: Anpviz IPC-D240W-S V3.5.2.1 captured from the owner’s MCA40E camera; the V3.6.3.1 comparison image is an MCA50E image sent in error and was not flashed to this model.
Finding
The browser limit and server-side accepted/stored lengths disagree; the new image changes a UI check but retains inconsistent layers.
Status in this image: original finding or lead.
Evidence limit: The precise cause of the old live password-prefix observation is not fully established.
