How to security-review a PR with OWASP Top 10 in mind

👤 Developers doing self-review before requesting human review ⏱ ~20 min intermediate

Quand l'utiliser : Before you click 'Ready for review' on a PR that touches auth, data, or input handling.

Déroulement

Point at the diff

Review the current PR against OWASP Top 10:2025. Focus on auth and input handling.✓ Copié

→ Findings mapped to Top 10 categories with line references
Prioritize

Group findings into 'must-fix before merge' vs 'follow-up issue'. Cite the specific ASVS requirement.✓ Copié

→ Ranked list with ASVS IDs
Generate fixes

For each must-fix, propose the minimal diff.✓ Copié

→ Patch diffs keyed to findings

Résultat : A PR that ships with known security issues resolved, with traceable requirements.

Pièges

Over-alerting on benign patterns — Ask Claude to show the exploit path concretely; if it can't, downgrade the severity

Run a lightweight threat model on a new feature

👤 Engineers designing a feature involving user data ⏱ ~40 min advanced

Quand l'utiliser : Design stage, before writing the code, when the blast radius is still negotiable.

Déroulement

Describe the feature

Feature: share-by-link for customer reports. Users generate tokenized URLs valid 7 days. Threat-model with OWASP agentic AI guidance included.✓ Copié

→ STRIDE-style list of threats
Pick controls

For each threat, what's the cheapest control that mitigates 80%?✓ Copié

→ Per-threat control + rejection rationale for expensive ones

Résultat : A threat model document you can attach to the design doc.

Pièges

Over-engineered control list — Explicitly limit to top-5 threats by likelihood × impact

Harden an AI agent integration against prompt injection

👤 Engineers shipping Claude/LLM-powered features ⏱ ~30 min advanced

Quand l'utiliser : You're about to let an LLM touch user data or call tools.

Déroulement

Describe the agent surface

Our agent reads support emails and can call 3 tools: refund(), tag_account(), escalate(). Review for agentic AI risks.✓ Copié

→ Prompt-injection vectors, tool-misuse risks, data exfil paths
Design guardrails

Propose a minimal guardrail set: which tools need human confirm, which inputs need sanitization, what logging is required.✓ Copié

→ Concrete guardrail spec

Résultat : A hardened agent design with documented guardrails.

Pièges

Relying on prompt-based defenses alone — Combine with deterministic controls — human-in-loop for destructive tools, allowlists for URLs

Audit for language-specific security quirks

👤 Reviewers checking a codebase in a language they don't know deeply ⏱ ~15 min intermediate

Quand l'utiliser : You're reviewing Python code as a TS native, or vice versa.

Déroulement

Scope to language

Review this Python module for Python-specific OWASP quirks (pickle, yaml.load, shell=True, etc.).✓ Copié

→ Language-specific findings beyond generic Top 10

Résultat : Catches that a language-agnostic review would miss.

Coût et limites

Coût d'exécution

Quota d'API: None
Tokens par appel: 5-20k per review depending on code size
Monétaire: Free
Astuce: Scope reviews to changed files, not the whole repo.

Sécurité

Permissions, secrets, portée

Stockage des identifiants : No credentials

Sortie de données : Code is sent to Claude for inference

Not a replacement for human security review on anything material. Treat as a force multiplier.

Dépannage

Erreurs courantes et correctifs

Claude ignores OWASP context and gives generic advice

Explicitly name the guidance: 'Apply OWASP Top 10:2025 category A03:2025 Injection here.'

Too many false positives

Require an exploit walkthrough before accepting a finding
