Hunt injection into database connection strings and JDBC or driver URLs where untrusted input sets the host, a driver property, or a URL parameter, turning a data connection into a request to an attacker server or an unsafe driver feature. Covers a tenant, hostname, or option taken from input and spliced into a connection URL, driver properties that enable local file reads, arbitrary command execution, or class loading, and multi-attribute connection strings where an extra property overrides a…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Hunting connection-string and JDBC-URL injection: when the connection target is attacker-set Connection strings and driver URLs look like inert configuration, but they are richly featured: they carry the host to connect to and a set of driver properties, and many drivers expose properties that read local files, load classes, run initialization commands, or disable transport security. When an application builds one of these from untrusted input, a tenant identifier, a hostname, a region, or an options blob, the attacker can redirect the connection to a server they control, or append a property that flips a dangerous driver feature on. The result ranges from credential capture at a rogue server to local file reads and code execution through the driver. You find it by locating every place a connection string or URL is built from input and asking which host or property the attacker can set. ## When to use - An application builds a database or service connection string or driver URL from user or tenant input. - A hostname, port, tenant, region, or driver option in a connection comes from a request or stored value. …

How to install
mdr add unboundcompute/security-agent-skills/hunting-connection-string-and-jdbc-url-injection@sha256:3f67b78a9b0c78afThe line at the top of this page pins the label git:20260826.c45369b, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
