Summary Adminer blocks `ATTACH` queries for SQLite to prevent arbitrary file creation. However, `VACUUM INTO` is not blocked and achieves the same result: writing a database file containing attacker-controlled PHP code to any path with any extension. An authenticated SQLite user can write a web shell to the web root and execute commands. Originally reported in Adminer: GHSA-q4f2-39gr-45jh

Root Cause sql.inc.php, line 146: ```php if (DIALECT == "sqlite" && preg_match("~^$space*+ATTACH\\b~i", $q, $match)) { // blocked } ``` Only `ATTACH` is in the blocklist. `VACUUM INTO` (available since SQLite 3.27.0) writes the entire database to a new file at an arbitrary path with an arbitrary extension. It is not checked.

Steps To Reproduce

1. Login to SQLite 1. Open AdminNeo and select driver: SQLite 2. Login and create a new database (e.g., `stage.db`)

2. Inject PHP code and write the shell Navigate…

# Patch Next advisory brief: CVE-2026-96630

Advisory: AdminNeo: RCE via SQLite VACUUM INTO (ATTACH Blocklist Bypass)
IDs: CVE-2026-96630, GHSA-q5mp-gfjf-cf2j
Record: https://patchnext.com/advisories/cve-2026-96630 (revision 2, source checked 31 Oct 2026, 06:45 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 7.2)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: adminneo-org/adminneo 5.5.1. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist adminneo-org/adminneo: affected < 5.5.1; fixed in 5.5.1

## Suggested inspection (read-only)
- Packagist adminneo-org/adminneo: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on adminneo-org/adminneo.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
