Description
Drupal's uniqueness checking for certain user fields is inconsistent depending on the database engine and its collation. As a result, a user may be able to register with the same email address as another user. This may lead to data integrity issues. This issue affects Drupal Core: from 8.0.0 before 10.2.11, from 10.3.0 before 10.3.9, from 11.0.0 before 11.0.8.

Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for drupal/core, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update drupal/core to 10.2.11 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-7cwc-fjqm-8vh8 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.
