7.5 highCVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:HCVE-2020-35711
High (7.5) in arc-swap project arc-swap. EPSS 1.6% chance of exploitation in the next 30 days. Fixed in arc-swap 0.4.8, 1.1.0.
An issue has been discovered in the arc-swap crate before 0.4.8 (and 1.x before 1.1.0) for Rust. Use of arc_swap::access::Map with the Constant test helper (or with a user-supplied implementation of the Access trait) could sometimes lead to dangling references being returned by the map.
