GHSA-PQF9-H8G4-8GMH Vikunja: Unbounded CSV row cardinality permits API process termination

Unbounded CSV row cardinality permits API process termination Summary The authenticated v2 CSV migration route caps upload bytes but not parsed row cardinality. It reads every record into a string and then materializes a full task object for every row before insertion. Two million one-cell rows f...

GHSA-XXC3-XPMC-VMVR Vikunja: Unbounded nested task-filter recursion permits API process termination

Unbounded nested task-filter recursion permits API process termination Summary Authenticated task-list routes accept a filter expression without a length or nesting-depth bound, preprocess it, parse it recursively through fexpr, and recursively convert the resulting expression tree. A syntactical...

CVE-2026-91968: Uncontrolled Recursion

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 an...
