Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
SOY CMS 3.0.2.327 and earlier is affected by Unauthenticated Remote Code Execution (RCE). The allows remote attackers to execute any arbitrary code when the inquiry form feature is enabled by the service. The vulnerability is caused by unserializing the form without any restrictions. This was fixed in 3.0.2.328.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis
How this class of weakness works · CWE-502

The application rebuilds objects from attacker-supplied serialized data, and the act of rebuilding can trigger dangerous code paths. In many runtimes this leads straight to remote code execution. The durable fix is to avoid deserializing untrusted input — or to use a strict, type-limited format with integrity checks.
