CVE-2026-34127

A stored
cross-site scripting (XSS) vulnerability has been identified in the web
management interface of TP-Link's TL-SG108PE v5 switch due to improper sanitation of the SYSNAM
configuration parameter during configuration file import. An attacker with
administrator access can inject malicious script into the device configuration,
which may be stored and executed in the administrator’s browser when the
affected interface is viewed.    





Successful
exploitation may allow session cookie theft, unauthorized configuration
changes, or access to sensitive information exposed through the management
interface.
