Weaknesses in browser-delivered code — JS/TS, JSX/TSX, Vue, Svelte, Angular, HTML, templates, bundler and Docker config. DOM XSS and code-exec sinks, secrets in bundles or config.js, build-inlined REACTAPP/NEXTPUBLIC/VITE env, source maps and dev servers shipped in images, tokens in localStorage or non-httpOnly…

Find broken or misused cryptography: weak hashes and ciphers, unsalted password storage, predictable randomness, bad key or IV handling, disabled certificate verification.

visa/visa-vulnerability-agentic-harness

Skill Claude CodeCodex

Find state-changing requests that a third-party origin can forge: missing or unverified CSRF tokens, unsafe SameSite, and CORS that trusts a reflected Origin with credentials.

Skill Claude CodeCodex

Hunt injection classes (SQL, NoSQL, OS command, LDAP, XPath, XXE, CRLF, SSTI, open redirect, path traversal, SSRF, server-emitted XSS, ReDoS) under a source/sink/no-defence hard gate. Ships probe.sh: a per-class sink sweep plus a census of the defences present.

Find unsanitised input reaching log sinks: forged log records, injected control characters, and sensitive values written to logs.

visa/visa-vulnerability-agentic-harness

Skill Claude CodeCodex

Find business-logic defects: missing validation on amounts and quantities, race conditions and TOCTOU, workflow steps that can be skipped or replayed.

visa/visa-vulnerability-agentic-harness

Skill Claude CodeCodex

Find weaknesses that consist of an ABSENT control — no rate limit, no session invalidation, no cookie flags, debug left on, secrets or PII stored in cleartext — by enumerating every site the control belongs and checking each.

visa/visa-vulnerability-agentic-harness

Skill Claude CodeCodex

Find sensitive data reaching somewhere it should not: PII, credentials or internals in HTTP responses, logs, error pages, templates, caches, headers, debug routes, or stored unprotected. Point-of-occurrence — no injection path required. Ships probe.sh, which greps every leak channel (debug flags…

After confirming a weakness, sweep the repository for every other site of the same pattern and report each one — a class confirmed at one location is almost never present at only one location.
