Name of the Vulnerable Software and Affected Versions Activepieces versions prior to 0.83.0
Description The /api/redirect OAuth callback endpoint embeds the user-supplied code query parameter directly into an inline script block without proper escaping. This allows an unauthenticated attacker to send a crafted request that executes arbitrary JavaScript in the Activepieces origin when opened by a logged-in user, potentially enabling the theft of session tokens or unauthorized authenticated API calls.
Recommendations Update to version 0.83.0.
