Machine-written summary

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

Obot versions before 0.23.0 are affected. An unauthenticated attacker who gets a logged-in user to open a crafted authorization link can obtain an access token and refresh token for that user, which works against the Obot API endpoints the user can reach. Upgrade to Obot 0.23.0 or later.

Written 1 Nov 2026.
