PYSEC-2026-2486 Galaxy NG: command injection vulnerability

A command injection vulnerability was found in galaxyng. The dogitcheckout function in the legacy role import API v1 interpolates unsanitized git ref names branch/tag names into shell commands executed via subprocess.run with shell=True. An authenticated user who controls a git repository can...

Vantage6: Set admin user and password from environment or configuration

ImpactVantage6 currently provides an initial user with username root and password root. This is not ideal for the following reasons:- Attackers know that almost all vantage6 servers have a user with username root that probably has admin rights- The initial password is very weak and it is possible...

PYSEC-2026-2466 Dulwich has unbounded memory allocation in receive-pack from crafted thin packs

Impact An uncontrolled-resource-consumption memory exhaustion denial-of-service vulnerability CWE-400 / CWE-789. A client with push access could push a tiny crafted thin pack 174 bytes whose delta header declares a huge destsize. When dulwich ingested it via addthinpack / applydelta, it would...
