warp: Improper Neutralization of Special Elements used in an OS Command

CVE-2026-48731 is a high-severity improper neutralization of special elements used in an OS command vulnerability in warp from Warpdotdev, with a CVSS 3.1 base score of 7.8 out of 10. It can be exploited with local access to the system by an unauthenticated attacker, but only if a user takes part, for example by opening a link or file. There is no confirmed exploitation so far. EPSS estimates a 0.89% chance of exploitation within 30 days, higher than 60% of scored CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Check which version of warp you run against the affected versions below, and install the vendor's latest release.
  2. Read the advisory on github.com for workarounds and exact fixed builds.
  3. Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.

Official description

Warp is an agentic development environment. From 0.2024.02.20.08.01.stable_01 until 0.2026.05.06.15.42.stable_01, Warp contains a command injection issue in the Linux external editor launcher. Warp expanded freedesktop .desktop Exec templates for affected editor integrations and executed the expanded command through a shell. A user who opens an attacker-controlled local file path through an affected external editor or system-default editor route can cause shell syntax embedded in that path to execute as the local user. This vulnerability is fixed in 0.2026.05.06.15.42.stable_01.

The underlying weakness: Improper Neutralization of Special Elements used in an OS Command

The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command before it is sent to a downstream component.

How developers prevent this class of flaw

  • If at all possible, use library calls rather than external processes to recreate the desired functionality.
  • For any data that will be used to generate a command to be executed, keep as much of that data out of external control as possible. For example, in web applications, this may require storing the data locally in the session's state instead of sending it out to the client in a hidden form field.
  • For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.
