kas's late signature validation may allow unnoticed repository manipulations

ImpactSo far, kas checks out and processes repositories regarding configuration includes prior to validating signatures of those repositories. This may allow to replace on original repository with one under the control of an attacker under very specific conditions.First of all, the attacker must...

PYSEC-2026-2384 AsyncSSH `AuthorizedKeysFile %u` path traversal allows attacker-selected authorized keys to authenticate a traversal username

Summary AsyncSSH 2.22.0 expands the OpenSSH-compatible AuthorizedKeysFile %u token with the raw SSH username during pre-authentication server config reload. A server configured with a documented per-user key pattern such as AuthorizedKeysFile authorizedkeys/%u can be made to read an authorized-ke...

PYSEC-2026-2960 pretix vulnerable to Authorization Bypass Through User-Controlled Key

When creating an export through the pretix API, API clients are returned an UUID value for their export job a long, random string like 35742818-c375-4d15-839f-d49aecce94d6. Using this UUID, the API client can then request the actual file for download. The same kind of UUID is used in other places...
