Description
In phpMyAdmin 4.x before 4.9.5 and 5.x before 5.0.2, a SQL injection vulnerability was found in retrieval of the current username (in libraries/classes/Server/Privileges.php and libraries/classes/UserPassword.php). A malicious user with access to the server could create a crafted username, and then trick the victim into performing specific actions with that user account (such as editing its privileges).

Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for phpmyadmin/phpmyadmin, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update phpmyadmin/phpmyadmin to 4.9.5 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2020-10804 is resolved across your whole dependency graph.
Workarounds
Until you can upgrade, make sure every query built from user input uses parameterised statements or a prepared-statement API rather than string concatenation, and reduce the database account's privileges so an injected query cannot read or alter data beyond what the feature needs.
Fixing This On Your OS
If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.
