CVE-2023-3232

Unspecified impact via unauthenticated endpoint deserialization

Published Jun 14, 2023 · Updated Aug 2, 2024

Deserialization in CRMEB 4.6.0 and earlier allows remote attackers to cause unspecified impact via /api/wechat/app_auth. Public records identify the POST endpoint and untrusted-data deserialization, but do not disclose the input field, code-level sink, or resulting object use. No authentication or user interaction is required, but the published CVSS assessment limits reachability to an adjacent network.
