databasement: Remote code execution via database name argument injection
Summary
databasement is a self-hosted database backup manager with a web interface. Versions 1.0.0 up to 1.8.1 pass the database name to mariadb-dump without proper argument separation, so an authenticated user can inject dump options. This allows an arbitrary file write, for example into a web-served PHP file, which leads to remote code execution.
Affected
- databasement 1.0.0 up to but excluding 1.8.2
- Source: GitHub advisory GHSA-hm57-pvxc-4pcm and CVE record
Fixed in
- Upgrade to databasement 1.8.2 or later
- Fix commits: 22258e3eac594e653f9d04a69d93e83923d61499 and 2d2761905594a2fa2c3d81d48a7c8b6a1784862c
- Unknown: whether 1.8.2 also fixes the similar PostgreSQL dump and restore code paths; verify with the maintainer.
Workaround
- Unknown. No vendor-documented interim workaround found.
- Until patched, restrict access to the web interface to trusted networks or VPN.
- Remove unneeded user accounts.
- Ensure the application web root is not writable by the application user.
Exploitation
- Requires an authenticated user account.
- CVSS 8.8 (v3.1), CWE-88.
- CISA SSVC: exploitation status poc, automatable: no, technical impact: total.
- No public exploit confirmed by VulDB; no known in-the-wild exploitation.
- Exploit availability is unconfirmed: a Positive Technologies write-up (PT-2026-110344) exists but its content was not verified.
Our recommendation
- Upgrade to databasement 1.8.2 or later.
- Check whether the web interface is reachable from untrusted networks and restrict it if so.
- Review user accounts and remove unneeded ones.
- Check that the application web root is not writable by the application user.
- Monitor for unexpected file changes in the web root.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.

Original description (NVD)
databasement before 1.8.2 allows remote code execution because it runs certain commands (e.g., mariadb-dump) with a database name that can be specified by any authenticated user. For example, --result-file=/app/public/index.php can write to index.php. In other words, quoting prevents OS command injection in mariadb-dump, but the argument injection alone is sufficient for code execution indirectly. NOTE: the project's composer.json file does not indicate an independently published databasement Composer package.
