Description
DIRAC is an interware, meaning a software framework for distributed computing. Prior to version 8.0.41, during the proxy generation process (e.g., when using dirac-proxy-init), it is possible for unauthorized users on the same machine to gain read access to the proxy. This allows the user to then perform any action that is possible with the original proxy. This vulnerability only exists for a short period of time (sub-millsecond) during the generation process. Version 8.0.41 contains a patch for the issue. As a workaround, setting the X509_USER_PROXY environment variable to a path that is inside a directory that is only readable to the current user avoids the potential risk. After the file has been written, it can be safely copied to the standard location (/tmp/x509up_uNNNN).

Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for dirac, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update dirac to 8.0.41 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-v6f3-gh5h-mqwx is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
