CVE-2026-73084 - Activepieces: Reflected Cross-Site Scripting in OAuth Redirect Endpoint
CVE ID : CVE-2026-73084

Description : Activepieces is an open source AI workflow automation platform. Prior to 0. 83. 0, the /api/redirect OAuth callback endpoint embeds the user-supplied code query parameter directly into an inline script block without proper escaping.
A crafted request to /api/redirect with a malicious code value can break out of the script context and execute arbitrary JavaScript in the Activepieces origin when a logged-in user opens it. An unauthenticated attacker can access the victim's session tokens or make authenticated API calls on the victim's behalf. This issue is fixed in version 0. 83. 0.
Severity: 0.0
