This vulnerability affects the _get_file_id function within the uploaded file handler of chatchat-space Langchain-Chatchat (up to version 0.3.1.3). The issue arises from insufficient randomness in values generated, which could potentially be manipulated by an attacker with local network access. The attack complexity is high and exploitation is difficult. The vulnerability has a CVSS 4.0 base score of 2.1, indicating low severity. No official remediation or patch has been released by the vendor as of the published date.

The impact is limited due to the low CVSS score (2.1), high attack complexity, and requirement for local network access. The insufficient randomness could potentially allow an attacker to predict or influence file identifiers, but no further impact such as privilege escalation or data disclosure is described. Exploitation is difficult and no known exploits are reported in the wild.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since the vendor has not responded or released a fix, users should monitor official channels for updates. Given the attack requires local network access and is difficult to exploit, restricting local network access to trusted users may reduce risk until a patch is available.
