CVE-2020-26261 – user-readable api tokens in systemd units

https://notcve.org/view.php?id=CVE-2020-26261

jupyterhub-systemdspawner enables JupyterHub to spawn single-user notebook servers using systemd. In jupyterhub-systemdspawner before version 0.15 user API tokens issued to single-user servers are specified in the environment of systemd units. These tokens are incorrectly accessible to all users. In particular, the-littlest-jupyterhub is affected, which uses systemdspawner by default. This is patched in jupyterhub-systemdspawner v0.15 jupyterhub-systemdspawner permite que JupyterHub genere servidores de portátiles de un solo usuario utilizando systemd. • https://github.com/jupyterhub/systemdspawner/blob/master/CHANGELOG.md#v015 https://github.com/jupyterhub/systemdspawner/commit/a4d08fd2ade1cfd0ef2c29dc221e649345f23580 https://github.com/jupyterhub/systemdspawner/security/advisories/GHSA-cg54-gpgr-4rm6 https://pypi.org/project/jupyterhub-systemdspawner • CWE-668: Exposure of Resource to Wrong Sphere •
