Loading vulnerability…
A deserialization vulnerability in funadmin up to 7.1.0-rc4 affects the backend endpoint implemented by the getMember function in app/common/service/AuthCloudService.php. By manipulating the cloud_account argument, an attacker can cause the application to deserialize attacker-controlled data, enabling remote exploitation.

Repository contains a minimal proof-of-concept for CVE-2026-2898 affecting FunAdmin <= 7.1.0-rc4. Structure: (1) README.md describing an insecure deserialization issue where `cloud_account` is passed to PHP `unserialize()` in `AuthCloudService::getMember`, and (2) exploit.py, a Python script that takes `--url` and `--payload` and POSTs the payload as `cloud_account` to `{target}/index.php`. The exploit’s capability is limited to delivering an attacker-controlled serialized string and printing the server response; it does not include gadget-chain construction, authentication bypass, or an RCE payload generator, so successful code execution depends on the target environment and available PHP gadget chains.
