Summary

### Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-xxc3-xpmc-vmvr. This link is maintained to preserve external references. ### Original Description vikunja versions before 2.6.0 contain a resource exhaustion vulnerability in the task-filter endpoint that accepts deeply nested filter expressions without recursion depth limits. Authenticated attackers can supply thousands of nested parentheses in the filter query parameter to exhaust memory and terminate the API process.

Affected packages

Remediation: No patched version is listed by GitHub.
