CVE-2026-48914
Description détaillée
A flaw was found in QEMU's virtio-blk device. The issue arises because the device does not properly validate the size of input descriptors before writing data. A malicious guest with high privileges could exploit this vulnerability by submitting a malformed virtio-blk SCSI request, leading to an out-of-bounds write in the host heap memory and a potential denial of service (DoS) for the QEMU process.

CVE-2026-49347
Quest Bot is an opensource Discord Bot. Prior to version 1.1.8, any user who can access the ticket panel can repeatedly create new ticket channels. The latest release still creates a new database ticket and Discord channel for every completed ticket modal submission, without checking whether the same user already has an open ticket and without applying a cooldown. This issue has been patched in version 1.1.8.
CVE-2026-48485
Quest Bot is an opensource Discord Bot. Prior to version 1.1.6, the latest release suppresses mentions when creating, unbanning, unwarning, kicking, muting, and unmuting, but stored warning reasons are still printed by /warns without mention suppression. A moderator can create a warning with @everyone or @here in the reason, then make the bot later output that reason through /warns, causing a mass ping if the bot has permission. This issue has been patched in version 1.1.6.
CVE-2026-47197
Quest Bot is an opensource Discord Bot. Prior to version 1.1.6, a moderator with the relevant Discord permission bit can use the bot to moderate users above them in the Discord role hierarchy, as long as the bot itself outranks the target. This bypasses Discord’s normal role hierarchy protections and lets lower-ranked moderators ban, kick, timeout, untimeout, warn, or rename higher-ranked users. This issue has been patched in version 1.1.6.
