CVE-2026-100293

Improper verification of cryptographic signature in Anjvision YSSD-RTMP-H5

Published Sep 29, 2026 CVSS 4.0 · 8.7 High EPSS < 1% KEV · Not listed
Description
In Anjvision YSSD‑RTMP‑H5 firmware version 3.3.2.4, both the local and cloud update mechanisms apply new firmware without any cryptographic verification, relying only on basic hashing. This design allows an attacker who can reach the update routine to introduce untrusted firmware images that the device will accept as valid.
