Local code execution via documentation links

Published Apr 28, 2022 · Updated Aug 3, 2024

Code injection in JetBrains Rider before 2022.1 allows local users to execute code by activating a link in ReSharper Quick Documentation. JetBrains identifies link handling in ReSharper Quick Documentation as the vulnerable locus but has not disclosed the improper link-processing operation. Exploitation requires high local privileges and user interaction; resulting code execution can read or alter data in the affected user context.
