CVE-2026-66881

CVE-2026-66881 affects Livebook: path traversal via URL-type file entries allows an attacker-authored notebook to cause arbitrary file writes controlled by the attacker. The root cause is that Livebook resolves the entry name beneath the session temp directory without enforcing containment, and f...

EUVD-2026-53384

A flaw was found in the user-event metrics recording of Keycloak. When metrics are enabled, the system records raw error messages from failed account operations as Prometheus metric labels. Because these error messages can include user-supplied input like nonexistent client IDs, an authenticated...

UBUNTU-CVE-2026-64567

In the Linux kernel, the following vulnerability has been resolved: btrfs: reject free space cache with more entries than pages When loading a v1 free space cache, loadfreespacecache takes numentries and numbitmaps straight from the on-disk btrfsfreespaceheader. That header is stored in the...

CVE-2026-64574

CVE-2026-64574 affects the Linux kernel’s wifi mac80211 subsystem. When ieee80211_vif_update_links() adds new links and drv_change_vif_links() fails, new link debugfs entries may still point to freed memory, causing a use-after-free in ieee80211_if_read_link() and a potential local denial-of-serv...

Web Cache Overflow: Exploiting Imprecise Keys for Cache Degradation and Beyond

Web caches support the scalability needs of contemporary web applications by storing frequently accessed objects closer to clients. Web caches are conceptually associative arrays, tracking stored objects using cache keys consisting of HTTP request fields. However, these cache keys are often...

PYSEC-2026-3615 QTINeon has unauthenticated relay-to-host amplification via unbounded RECONNECT_REQUEST forwarding

Impact The relay's reconnect handler forwards every RECONNECTREQUEST to the host without deduplication or a size cap on the pendingReconnects map, unlike the connect flow which guards against this with maxPendingConnections. An unauthenticated attacker who knows a valid session ID can send...
