HIGHLong base64-encoded blob hidden in the skill documentationSS-SKILL-INJECT-B64-PAYLOAD-01 · Prompt injection · docs/benchmarks/submission/witness.json
HIGHonce decoded by the agent, an encoded payload has the same impact class as plain-text injection.
Why it matters

A base64 string of 128+ characters appears in a documentation file. Encoded prompt injection hides the hostile instruction in base64 — invisible to keyword filters — and relies on the agent's ability to decode it at runtime. There is no normal authoring reason to embed a multi-hundred-byte base64 blob in skill docs.

How to fix
Remove the encoded blob, or decode it and review what it actually contains.
  1. Decode the base64 string and confirm it is not an instruction directed at the agent.
  2. Move any legitimate binary or signature data into a dedicated file (*.sig, SIGNATURES) outside the documentation.

  1. Delete the imperative ("run this", "execute the following") from inside the fence.

Why it matters

The phrase {match} matches a known role-override jailbreak — DAN, "developer mode", "jailbroken", "unrestricted", or an evil/malicious persona. Embedded in a skill, it tries to push the agent into an adversarial role that drops its safety constraints, without the person running the skill realizing it.
