The `get_error<E>` operation also performed an unchecked cast to a\ncaller-selected type. Finally, concurrent replacement or clearing could free a\nvalue while another thread cloned it. Ordinary safe Rust could therefore cause\nmismatched deallocation, type confusion, and use-after-free. Crates that\nre-exported this API are affected transitively.\n\nVersion 2.0.0 replaces the raw pointers with owned `Box<dyn Any + Send>` values\nbehind a mutex, performs checked downcasts, and uses a mutation generation so\nconcurrent stores and clears win safely. There is no reliable workaround while\ncalling the affected registry API. Upgrade to 2.0.0 or later and avoid\nprocess-global error state where possible.","state":0,"publishedAt":"2026-08-09T12:00:00+00:00","modifiedAt":"2026-10-12T18:00:14.905022+00:00","affected":[{"ecosystem":"crates.io","name":"dcrypt-api","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0.0.0-0"},{"kind":"fixed","version":"2.0.0"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[],"references":["https://crates.io/crates/dcrypt-api","https://rustsec.org/advisories/RUSTSEC-2026-0242.html","https://github.com/ioi-foundation/dcrypt/commit/c99cc86f0ee353010cd202cbcd2c310371b0bbb8","https://github.com/ioi-foundation/dcrypt/releases/tag/v2.0.0"],"sourceUrl":"https://osv.dev/vulnerability/RUSTSEC-2026-0242","license":"OSV · upstream source license applies","key":"osv:RUSTSEC-2026-0242","identifiers":["RUSTSEC-2026-0242","GHSA-7hc7-h3f2-r4j6"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
