Common Manus issues affecting integrations
Autonomous security decisions without human review
Manus configures authentication, sets file permissions, and chooses security-sensitive patterns autonomously. These decisions are made without context about your threat model and may be inadequate for your use case.
Unknown packages installed without vulnerability audit
Manus installs dependencies autonomously from web research and may choose packages with known CVEs, low maintenance status, or malicious forks. There is no automatic supply chain security check.
Outdated patterns sourced from web research
Manus browses the web to inform implementation decisions. It can pull code patterns, library versions, and architectural approaches from outdated blog posts or Stack Overflow answers.
Slack API issues we find in Manus apps
Request signature verification missing
AI-generated Slack webhook handlers don't verify the X-Slack-Signature header, allowing anyone to send fake events to your endpoint.
Not responding within 3 seconds to events
Generated event handlers try to process everything synchronously before responding, causing Slack to retry events and eventually disable your endpoint due to timeout.
Bot token and user token confused
AI tools use the bot token for actions that require a user token (or vice versa), causing permission errors or posting messages as the wrong entity.
