Phishing via insufficient redirect URL validation
Published Jun 6, 2025 · Updated Apr 28, 2026
Open redirect in Automattic Newspack Newsletters 3.13.0 and earlier allows remote attackers to send users to malicious sites. Published records identify insufficient validation of a redirect URL but do not disclose the responsible endpoint, parameter, or function. Exploitation requires a user to follow a crafted link or perform another attacker-induced action, enabling phishing through a trusted site without reported direct data access or service interruption.
