CVE-2022-29816

IDE message alteration via HTML injection

Published Apr 28, 2022 · Updated Aug 3, 2024

HTML injection in JetBrains IntelliJ IDEA before 2022.1 allows local users to alter IDE message content through crafted input. JetBrains identifies IDE messages as the affected locus but has not disclosed which message producer accepts the input or which output-encoding operation is missing. Exploitation requires low local privileges and user interaction, and the published impact is limited to modification of message content.
