Resource Exhaustion

code.vikunja.io/api is vulnerable to a resource exhaustion. The vulnerability is due to the lack of recursion depth limits for deeply nested filter expressions in the task-filter endpoint, which allows an authenticated attacker to submit thousands of nested parentheses in the filter query...

CVE-2026-94538 WP File Download <= 6.3.9 - Missing Authorization to Authenticated (Subscriber+) Arbitrary File Deletion/Modification via 'task' Parameter to Multiple Functions

The WP File Download plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 6.3.9. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level...

CLEANSTART-2026-UV14417 Apache Airflow's Task SDK did not mask the contents of a Variable whose JSON value is a list, so secrets stored in that shape appeared in cleartext in task logs and in the Rendered Templates UI

Security vulnerability affects the airflow-3 package. Apache Airflow's Task SDK did not mask the contents of a Variable whose JSON value is a list, so secrets stored in that shape appeared in cleartext in task logs and in the Rendered Templates UI...

Vikunja: Task relation deletion does not check read access to the other task, allowing cross-project relation removal

Summary Deleting a task relation only requires write access on the base task. Unlike relation creation, it does not verify that the caller can read the other task. A user with write access to one project can therefore delete relations whose other end lives in a project they have no access to. Sin...

GHSA-8WVG-R2J4-3737 Vikunja: Assignee email addresses disclosed to read-only project members via the task assignees endpoint

Summary TaskAssginee.ReadAll returns assignee user objects without blanking the Email field, disclosing assignee email addresses to any read-only project member. Every sibling path that returns user objects obfuscates the email; this one does not. Details pkg/models/taskassignees.go lines 306-344...

Vikunja: API token scopes bypassed via task expand parameter (comments, reactions, time entry counts)

Summary API token permission checks only match the HTTP method and route path. The expand query parameter on task read endpoints embeds data from other permission groups task comments, reactions, time entry counts without checking whether the token holds those scopes. A token scoped only to tasks...

GHSA-W39F-H553-H2MX Vikunja: Cross-tenant task-position rows can be injected into arbitrary project views via the unvalidated project_view_id in the task position endpoint (v1 and v2)

Summary The task-position endpoint authorizes only the task side of the write: TaskPosition.CanUpdate delegates to Task.CanUpdate write access to the task's own project and the request body's projectviewid is never validated to belong to the task's project, nor is any access to that view required...
