CVE-2024-1353Network attack vector

Unspecified impact via untrusted picurl deserialization

Published Feb 9, 2024 · Updated May 8, 2025

Deserialization of untrusted data in PHPEMS 1.0 allows remote attackers to trigger unsafe object processing through a crafted picurl value. The index method in app/weixin/controller/index.api.php deserializes the attacker-controlled picurl argument without establishing that its serialized content is trusted. No authentication or user interaction is required; published assessments disagree on network reachability, and the resulting application behavior is undisclosed.
