Where this sits among everything scored
Real-World Exposure
vrana/adminerReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.
Description
Impact
Users of MySQL, MariaDB, PgSQL and SQLite are affected. XSS is in most cases prevented by strict CSP in all modern browsers. The only exception is when Adminer is using a pdo_ extension to communicate with the database (it is used if the native extensions are not enabled). In browsers without CSP, Adminer versions 4.6.1 to 4.8.0 are affected.
Patches
Patched by 4043092, included in version 4.8.1.
Workarounds
Do both:
- Use browser supporting strict CSP.
- Enable the native PHP extensions (e.g.
mysqli) or disable displaying PHP errors (display_errors).

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for vrana/adminer, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update vrana/adminer to 4.8.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-2v82-5746-vwqc is resolved across your whole dependency graph.
Workarounds
Escape or sanitise the affected output on the server side rather than relying on client-side filtering, and add a Content-Security-Policy that blocks inline script execution so injected markup cannot run even if it reaches the page.
How to detect GHSA-2v82-5746-vwqc
A community-maintained Nuclei template exists for this CVE. You can scan for it directly:
nuclei -id ghsa-2v82-5746-vwqc -u https://target- Template
- Adminer <=4.8.0 - Cross-Site Scripting
- Severity
- medium
- Impact
- Successful exploitation of this vulnerability could allow an attacker to inject malicious scripts into the Adminer interface, potentially leading to session hijacking, defacement, or theft of sensitive information.
- Remediation
- This vulnerability is patched in version 4.8.1. As workarounds, one can use a browser supporting strict CSP or enable the native PHP extensions (e.g. `mysqli`) or disable displaying PHP errors (`display_errors`).
