{"id":"GHSA-p749-9w62-w533","summary":"Tilt: Unauthenticated pprof debug endpoints on the Tilt HUD server","details":"## Summary\nThe Tilt HUD server mounts Go's `net/http/pprof` handlers under `/debug` with no access control. 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 `\u003e= 0.19.5, \u003c= 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.","aliases":["CVE-2026-55882","GO-2026-5533"],"modified":"2026-06-25T23:11:37.125815980Z","published":"2026-06-19T13:52:17Z","database_specific":{"nvd_published_at":null,"cwe_ids":["CWE-200"],"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2026-06-19T13:52:17Z"},"references":[{"type":"WEB","url":"https://github.com/tilt-dev/tilt/security/advisories/GHSA-p749-9w62-w533"},{"type":"WEB","url":"https://github.com/tilt-dev/tilt/pull/6776"},{"type":"PACKAGE","url":"https://github.com/tilt-dev/tilt"},{"type":"WEB","url":"https://github.com/tilt-dev/tilt/releases/tag/v0.37.4"}],"affected":[{"package":{"name":"github.com/tilt-dev/tilt","ecosystem":"Go","purl":"pkg:golang/github.com/tilt-dev/tilt"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0.19.5"},{"fixed":"0.37.4"}]}],"database_specific":{"last_known_affected_version_range":"\u003c= 0.37.3","source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/06/GHSA-p749-9w62-w533/GHSA-p749-9w62-w533.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"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"}]}
