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