PYSEC-2026-2009 virtualenv Has TOCTOU Vulnerabilities in Directory Creation

Impact TOCTOU Time-of-Check-Time-of-Use vulnerabilities in virtualenv allow local attackers to perform symlink-based attacks on directory creation operations. An attacker with local access can exploit a race condition between directory existence checks and creation to redirect virtualenv's appdat...

mktemp: empty TMPDIR creates temp files in CWD instead of /tmp

The mktemp utility in uutils coreutils fails to properly handle an empty TMPDIR environment variable. Unlike GNU mktemp, which falls back to /tmp when TMPDIR is an empty string, the uutils implementation treats the empty string as a valid path. This causes temporary files to be created in the...

RabbitMQ: RabbitMQ: Persistent foreign bindings allow unauthorized message routing

A flaw was found in RabbitMQ, a messaging and streaming broker. This vulnerability allows an attacker to establish persistent foreign bindings to reply-to destinations. This occurs because temporary queues are not properly removed, leaving behind active routing entries. This can lead to...
