mcp-atlassian is vulnerable to Denial of Service (DoS)

Low Risk
This Affects:
mcp-atlassianTL;DR
Affected versions of this package are vulnerable to uncontrolled resource consumption due to missing explicit timeout configuration on HTTP requests in the OAuth flow, which can cause connections to hang indefinitely when Atlassian APIs are slow or unresponsive. The issue impacts OAuth token exchange, token refresh, and cloud ID retrieval requests in src/mcp_atlassian/utils/oauth.py. Explicit connection (5 seconds) and read (20 seconds) timeouts mitigate the risk by preventing stalled connections and improving overall reliability.
