Description
Warp is an agentic development environment. From 0.2023.10.24.08.03.stable_00 until 0.2026.05.06.15.42.stable_01, Warp may open executable local files through the operating system default file handler. A malicious Markdown document or project can contain a local-file link that appears as normal rendered content. If a user opens the Markdown in Warp and clicks the link, affected builds may route the resolved local file to a platform file opener instead of limiting the action to safe viewer/editor targets. This vulnerability is fixed in 0.2026.05.06.15.42.stable_01.
