CVE-2026-34953
PraisonAI’s OAuthManager incorrectly accepts any bearer token that is not in its internal store, which is empty by default. This flaw lets an attacker authenticate with any token and gain full access to all tools and agent capabilities. The issue is fixed in version 4.5.97.
An official fix is available, so this entry is kept for 30 days and then removed automatically.
