In every case, if the deputy component has broader authority than any single request should use, a malicious or mistaken request can exploit that excess authority. The damage ranges from data corruption to unauthorized access to system compromise. The confused deputy problem is one of the most common and least understood security flaws in multi-component systems.","status":"active","vx_hash":"ed7d26b568beea95beb4600d06288909cd2f3a8ff281a92ff2b51c1e714937ef","semantic_hash":null,"version_hash":null,"version":1,"sources":[],"falsifiers":[],"tier":null,"backed":null,"transcludes":null,"chain_head":"66807b2d67abcd9358e6c16a1310e995705fb1da7126e3774714497ff0baa086","chain_length":1,"chain":[{"n":1,"op":"genesis","ts":"2026-07-17T02:43:37.094Z","actor":"owner","text_sha":"9a3f68f7364cbcf9b479fc6b499589a320fdbc50a8e8d8cc71303f9771da26d1","detail":{"divided_from":"body","block":10,"kind":"p"},"prev":"genesis","hash":"66807b2d67abcd9358e6c16a1310e995705fb1da7126e3774714497ff0baa086"}],"claim_ids":[],"last_op":{"op":"genesis","actor":"owner","ts":"2026-07-17T02:43:37.094Z"},"consolidated_into":null,"stable_url":"https://miscsubjects.com/i/div/what-is-confused-deputy/d10"},{"id":"d11","kind":"h","type":null,"order":11,"text":"### The Key Idea","status":"active","vx_hash":"ccd9fad37ced5ee5272cc265ca0d6420c4fa09500cd91576b890ad6ec1d3233c","semantic_hash":null,"version_hash":null,"version":1,"sources":[],"falsifiers":[],"tier":null,"backed":null,"transcludes":null,"chain_head":"db33c0d2161854567d82d7ac97c8c6844e89e229dcbd5179f84039d1d7be75d6","chain_length":1,"chain":[{"n":1,"op":"genesis","ts":"2026-07-17T02:43:37.094Z","actor":"owner","text_sha":"441af1806499f3c61d7189137057d9d38e063ccdca01d669193809ee90c0ef2d","detail":{"divided_from":"body","block":11,"kind":"h"},"prev":"genesis","hash":"db33c0d2161854567d82d7ac97c8c6844e89e229dcbd5179f84039d1d7be75d6"}],"claim_ids":[],"last_op":{"op":"genesis","actor":"owner","ts":"2026-07-17T02:43:37.094Z"},"consolidated_into":null,"stable_url":"https://miscsubjects.com/i/div/what-is-confused-deputy/d11"},{"id":"d12","kind":"p","type":null,"order":12,"text":"The problem is not that the deputy has authority.
