Brace expansion as known from sh/bash Security Fixes: The brace-expansion library generates arbitrary strings containing a common prefix and suffix. Prior to versions 5.0.5, 3.0.2, 2.0.3, and 1.1.13, a brace pattern with a zero step value e.g., 1..2..0 causes the sequence generation loop to run...

Jailbreaking the Matrix: Nullspace Steering for Controlled Model Subversion

Large language models remain vulnerable to jailbreak attacks -- inputs designed to bypass safety mechanisms and elicit harmful responses -- despite advances in alignment and instruction tuning. We propose Head-Masked Nullspace Steering HMNS, a circuit-level intervention that i identifies attentio...

CVE-2026-35599

Summary: CVE-2026-35599 affects Vikunja prior to version 2.3.0, where addRepeatIntervalToTime uses an O(n) loop to advance a date by RepeatAfter until it passes now. When a repeating task uses a 1-second interval and an old due_date, this can trigger billions of iterations, causing high CPU usage...

GHSA-R4FG-73RC-HHH7 Vikunja has Algorithmic Complexity DoS in Repeating Task Handler

Summary The addRepeatIntervalToTime function uses an On loop that advances a date by the task's RepeatAfter duration until it exceeds the current time. By creating a repeating task with a 1-second interval and a due date far in the past, an attacker triggers billions of loop iterations, consuming...
