Arbitrary file read via web-module path traversal
Published Mar 2, 2026 · Updated Mar 2, 2026
Path traversal in TP-Link Deco BE25 1.0 web modules through 1.1.1 Build 20250822 allows remote authenticated users to read files or interrupt service. TP-Link identifies only the web modules and has not disclosed the request parameter, handler, or filesystem operation that fails to confine attacker-controlled paths. Exploitation requires an authenticated client on the adjacent Deco network and can expose device files or interrupt the appliance, without reported file modification.
