Potential DoS via the Tudoor mechanism in eventlet and dnspython

eventlet before 0.35.2, as used in dnspython before 2.6.0, allows remote attackers to interfere with DNS name resolution by quickly sending an invalid packet from the expected IP address and source port, aka a "TuDoor" attack. In other words, dnspython does not have the preferred behavior in whic...

PYSEC-2026-2027 Voilà Local file inclusion

Impact Any deployment of voilà dashboard allow local file inclusion, that is to say any file on a filesystem that is readable by the user that runs the voilà dashboard server can be downloaded by someone with network access to the server. Whether this still requires authentication depends on how...

PYSEC-2026-1494 Kinto Attachment's attachments can be replaced on read-only records

Impact The attachment file of an existing record can be replaced if the user has "read" permission on one of the parent collection or bucket. And if the "read" permission is given to "system.Everyone" on one of the parent, then the attachment can be replaced on a record using an anonymous request...

PYSEC-2026-2006 Defining resource name as integer may give unintended access in vantage6

Impact Malicious users may try to get access to resources they are not allowed to see, by creating resources with integers as names. One example where this is a risk, is when users define which users are allowed to run algorithms on their node. This may be defined by username or user id. Now, for...
