Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Versions of the PraisonAI PyPI package before 4.6.59 skip webhook signature verification in the WhatsApp and Linear bot adapters whenever the secret environment variable is unset, which is the default. An unauthenticated attacker who can reach the bot's webhook endpoint can inject forged events that are processed as trusted messages. Upgrade praisonai to 4.6.59 or later. The source gives no workaround beyond setting the secret.
