DescriptionGitHub Advisory

CrawlChat is an open-source, AI-powered platform that transforms technical documentation into intelligent chatbots. Prior to version 0.0.8, a non-existing permission check for the CrawlChat's Discord bot allows non-manage guild users to put malicious content onto the collection knowledge base. Usually, admin / mods of a Discord guild use the jigsaw emoji to save a specific message (chain) onto the collection's knowledge base of CrawlChat. Unfortunately an permission check (for e.g. MANAGE_SERVER; MANAGE_MESSAGES etc.) was not done, allowing normal users of the guild to information to the knowledge base. With targeting specific parts that are commonly asked, users can manipulate the content given out by the bot (on all integrations), to e.g. redirect users to a malicious site, or send information to a malicious user. Version 0.0.8 patches the issue.

AnalysisAI

Improper permission validation in CrawlChat versions prior to 0.0.8 allows unauthenticated Discord guild members to inject malicious content into the bot's knowledge base through the jigsaw emoji feature, enabling attackers to manipulate chatbot responses across all integrations and redirect users to malicious sites. The vulnerability affects the AI/ML platform's ability to maintain knowledge base integrity, as normal users can bypass intended admin-only controls. …
