Local privilege escalation via missing signature verification
Published Nov 10, 2025 · Updated Nov 10, 2025
Improper signature verification in JetBrains ReSharper before 2025.2.4 allows local users to gain elevated privileges through DPA Collector. DPA Collector omits required cryptographic signature verification, although JetBrains has not disclosed the exact verification locus or untrusted input path. Exploitation requires a low-privileged local user on Windows and crosses a security boundary to expose or modify high-value data, with no reported service interruption.
