CVE-2026-123524

MediumCVSS 5.7/10Last modified Nov 12, 2026

Description

Vikunja from 0.23.0 before 2.7.1 contains an information disclosure vulnerability that allows project collaborators with write access to read tasks from inaccessible projects by registering webhooks. Because webhook payloads are built with the triggering user's permissions, attackers receive related_tasks titles, descriptions and metadata from private projects whenever another user modifies a linked task.
