How to Fix GHSA-v988-828w-xvf2

To remediate this vulnerability, upgrade all affected Rucio webui dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

rucio-webui fixed: 1.26.7 
pip install rucio-webui>=1.26.7
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

pip show rucio-webui

How to Check if You Are Affected

To determine whether your Python environment is affected by GHSA-v988-828w-xvf2, inspect your installed packages using pip:

pip show rucio-webui

Analyze the terminal output to locate any version of Rucio webui in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.26.7), your application is affected.

Note: The pip show rucio-webui command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-305: Authentication Bypass by Primary Weakness, where the authentication algorithm is sound, but the implemented mechanism can be bypassed as the result of a separate weakness that is primary to the authentication error. In Rucio webui, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### 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. ### References https://github.com/rucio/rucio/issues/4928
