R2ECAP: Stealthy poisoning via reused reasoning KV cache
R2ECAP studies how reused reasoning KV caches can retain adversarial influence after the original text has been discarded. Authors report up to 79% success under exact-cache reuse and 16 to 46% under cross-query reuse, without proving a cross-tenant commercial deployment exploit.

- supportsDiscarded malicious reasoning influences later answers through reused KV cache: The study demonstrates residual influence of an earlier attacker-shaped reasoning trace through subsequent KV cache reuse after the visible trace is removed.
