Last modified

CVE-2026-105674 is a high-severity vulnerability rated 8.7/10 on the CVSS scale. TP-Link Tapo C325WB V2 generates the pre-shared key used by its local media streaming service with a time-seeded pseudo-random number generator, making the key predictable and recoverable. An unauthenticated attacker on the adjacent network can recover the key and authenticate to the media streaming service without valid user credentials.  Successful exploitation may allow an unauthenticated adjacent-network attacker to access and take over live video and audio streams, compromising the confidentiality and integrity of camera media.. EPSS estimates a 0.20% chance of exploitation in the next 30 days.
