CVE-2026-36471 · Severity: medium · CVSS 5.8 · Published 2026-09-21

Technologies: CuteNews. Vendors: CuteNews.

Executive brief

CuteNews is a content management system for publishing news articles. An attacker can send a malicious POST request containing a crafted serialized PHP object to inject arbitrary values into the application's internal variables, potentially allowing account hijacking, session manipulation, or further code execution.

Technical details

The cn_parse_url() function in CuteNews 2.1.2 unsafely deserializes the __post_data parameter, which accepts base64-encoded PHP serialized objects. An unauthenticated remote attacker can send a crafted payload to inject arbitrary internal variables including __referer without authentication, leading to potential privilege escalation or authorization bypass.
