U.R. (5321)Taiwan CERT warns of three vulnerabilities in WeiQiao Information SSO and electronic directory system, including critical unauthenticated LFI (CVE-2026-3826)
TWCERT/CC disclosed three vulnerabilities affecting WeiQiao Information’s “Single Sign-On and Electronic Directory Service System”. Two medium-severity issues are open redirect (CVE-2026-3824) and reflected XSS (CVE-2026-3825), both described as exploitable by authenticated remote attackers via user interaction. A critical issue, CVE-2026-3826 (CVSS 9.8), is a local file inclusion flaw described as exploitable by an unauthenticated remote attacker and could enable server-side arbitrary code execution. TWCERT/CC recommends upgrading to IFTOP_P4_181 or later; versions before IFTOP_P4_181 are affected.
Ransomware group “Nitrogen” claims Foxconn breach with 8TB of alleged internal data, raising supply-chain exposure questions
Taiwan’s iThome reports that ransomware operators using the “Nitrogen” name have listed Foxconn (Hon Hai Precision Industry) as a victim on a dark-web leak site, claiming they stole 8TB of data comprising about 11 million files. The actors allege the haul includes confidential orders, projects, and design sketches tied to multiple technology companies, but the report notes those partner references are not yet independently verified. The disclosure follows a widely reported early-May IT outage at Foxconn’s U.S. Wisconsin campus; Foxconn confirmed an “IT network issue” and later stated that production operations at affected North American sites remained normal after response actions were initiated.
