## What is CVE-2026-55882?

CVE-2026-55882 is a high-severity vulnerability in tilt-dev tilt, published on 10 Jul 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

Tilt defines dev environments as code for microservice apps on Kubernetes. From 0.19.5 through 0.37.3, the Tilt HUD server mounts Go net/http/pprof handlers under /debug with no access control. When the HUD or apiserver listener is network-exposed, an unauthenticated caller can read process memory through /debug/pprof/heap and /debug/pprof/goroutine, including session and apiserver tokens, and degrade performance through /debug/pprof/profile or /debug/pprof/trace. This issue is fixed in version 0.37.4.

Weakness: CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor)

What it is: CVE-2026-55882 is a high-severity vulnerability in tilt-dev tilt, published on 10 Jul 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2026-55882 in the wild and no public exploit code.

Affected packages and fixed versions:
- github.com/tilt-dev/tilt (Go): affected from 0.19.5; fixed in 0.37.4
- github.com/tilt-dev/tilt (Go): affected from 0.19.5; fixed in 0.37.4
- github.com/tilt-dev/tilt (Go): affected from 0.19.5; fixed in 0.37.4

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.
