CVE-2026-123524

6.9 mediumEPSS 0.3%

Medium (6.9) in go-vikunja vikunja. EPSS 0.3% estimated probability of exploitation activity in the next 30 days.

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.
