Authentication Bypass Using an Alternate Path or Channel and Authentication Bypass by Primary Weakness in rucio-webui

  • Disclosed: 22.10.2021
  • Updated: 11.10.2026 12:19

Impact

rucio-webui installations of the 1.26 release line potentially leak the contents of cookies to other sessions within a wsgi container. Impact is that Rucio authentication tokens are leaked to other users accessing the webui within a close timeframe, thus allowing users to access the webui with the leaked authentication token. Privileges are therefore also escalated.

Rucio server / daemons are not affected by this issue, it is isolated to the webui.

Patches

This issue is fixed in the 1.26.7 release of the rucio-webui.

Workarounds

Installation of the 1.25.7 webui release. The 1.25 and previous webui release lines are not affected by this issue.
