## What is CVE-2026-48704?

CVE-2026-48704 is a high-severity vulnerability in warpdotdev warp, published on 24 Jun 2026. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.

### Official 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.

Weakness: CWE-20 (Improper Input Validation)

What it is: CVE-2026-48704 is a high-severity vulnerability in warpdotdev warp, published on 24 Jun 2026. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of CVE-2026-48704 in the wild and no public exploit code.

Affected product: warpdotdev warp. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
