Cloudreve: Storage-quota TOCTOU race allows quota bypass and storage-based denial of service

Summary Cloudreve v4 splits the storage-quota check reading the user's used bytes and comparing them to MaxStorage and the charge incrementing users.storage into two non-atomic steps in the PrepareUpload code path. This creates a Time-of-Check to Time-of-Use TOCTOU race condition. Any authenticat...

CVE-2026-86805

A flaw was found in glibc, specifically within its dynamic loader ld.so. A local attacker can exploit a time-of-check to time-of-use TOCTOU race condition to escalate privileges and execute arbitrary code. This occurs when the dynamic loader expands $ORIGIN in DTRPATH for setuid/setgid programs,...
