SCA: security update for github.com/tilt-dev/tilt (GHSA-c73q-8xxr-rgqm)

critical Tenable Self-Hosted Container Security Plugin ID 443606

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Tilt defines dev environments as code for microservice apps on Kubernetes. From 0.20.8 through 0.37.3, the
 Tilt HUD HTTP server registers handlers on a gorilla/mux router with no authenticating middleware. When
 the HUD is bound to a non-loopback address, an unauthenticated network caller can trigger developer-
 defined resources, tamper with Tiltfile arguments, read full engine state including the session token, and
 invoke apiserver resources through the token-attaching /proxy handler. This issue is fixed in version
 0.37.4. (CVE-2026-55884)

Solution

Update the github.com/tilt-dev/tilt library and its related packages to version 0.37.4 or later.
