Security considerations for Jackson JSON deserialization in Java applications. This skill covers common attack patterns such as the Empty Key ("") attack vector, polymorphic type handling, nested injection, and duplicate keys, along with their root causes and recommended mitigation strategies. It provides essential background knowledge and is highly useful for addressing related security vulnerabilities. It is always recommended to invoke this skill before working on relevant security fixes.

Works with any agent that supports SKILL.md skills.

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'jackson-security' ] || [ -L ~/.agents/skills/'jackson-security' ]; then echo 'A skill folder named jackson-security already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/cxcscmu/SkillLearnBench' "$d" && git -C "$d" checkout --quiet '726e1f79b96b0cb3d729d0e55a1c847e0b5353ae' -- 'skills/human_authored/fix-security-bug/jackson-security' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/human_authored/fix-security-bug/jackson-security' ~/.agents/skills/'jackson-security' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'jackson-security' ~/.claude/skills/'jackson-security' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
