When the HUD is network-exposed, an attacker can read process memory — including session and apiserver tokens — and hold the process under profiling.\n\n## Details\nA blank import of `net/http/pprof` registers its handlers on `http.DefaultServeMux`, which the HUD controller mounts under `/debug` on both the web router and the apiserver listener. `/debug/pprof/heap` and `/goroutine` expose process memory, including the session token (also issued in the `Tilt-Token` cookie) and the apiserver loopback bearer token; `/profile` and `/trace` let a caller sample the process for an arbitrary duration.\n\n## Impact\nAn unauthenticated caller who can reach the listener can extract process memory — including the session and apiserver tokens — and degrade performance by holding the process under CPU profiling or tracing. The leaked tokens compound the missing-authentication finding on the same server.\n\n### Conditions for exploitation\n- Affected version in `>= 0.19.5, <= 0.37.3`.\n- HUD (or apiserver) listener bound to a non-loopback address (`tilt up --host 0.0.0.0`, or `TILT_HOST` set).\n- Network reachability to the listener (default port `10350`).\n\n### Not affected\n- The default loopback-only bind is not reachable from the network.\n\n## Workarounds\nUse the default loopback bind (omit `--host`, unset `TILT_HOST`) so `/debug` is not remotely reachable. No complete workaround short of upgrading for non-loopback deployments.","state":0,"publishedAt":"2026-06-19T13:52:17+00:00","modifiedAt":"2026-06-25T23:11:06.0880198+00:00","affected":[{"ecosystem":"Go","name":"github.com/tilt-dev/tilt","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0.19.5"},{"kind":"fixed","version":"0.37.4"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V4","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:N/VA:L/SC:N/SI:N/SA:N","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"HIGH"}],"references":["https://github.com/tilt-dev/tilt/security/advisories/GHSA-p749-9w62-w533","https://github.com/tilt-dev/tilt/pull/6776","https://github.com/tilt-dev/tilt","https://github.com/tilt-dev/tilt/releases/tag/v0.37.4"],"sourceUrl":"https://github.com/advisories/GHSA-p749-9w62-w533","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-p749-9w62-w533","identifiers":["GHSA-p749-9w62-w533","CVE-2026-55882","GO-2026-5533"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
