From 0.24.0 through 0.37.3, the Tilt HUD WebSocket at /ws/view is gated by a CSRF token, but the token is served by the unauthenticated /api/websocket_token endpoint and the upgrader accepts clients that omit an Origin header. When the HUD is network-exposed, an attacker who can reach the listener can open the HUD WebSocket and receive the full view stream, including session state, Tiltfile contents, resource statuses, and continued updates. This issue is fixed in version 0.37.4.","state":0,"publishedAt":"2026-07-10T22:16:44.287+00:00","modifiedAt":"2026-07-14T15:17:04.873+00:00","affected":[],"metrics":[{"system":"CVSS 4.0 · security-advisories@github.com · Secondary","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:L/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","score":8.3,"severity":"HIGH"}],"references":["https://github.com/tilt-dev/tilt/commit/47393fba7f6ef5e305d5e814551feef8e4acbc0a","https://github.com/tilt-dev/tilt/pull/6776","https://github.com/tilt-dev/tilt/releases/tag/v0.37.4","https://github.com/tilt-dev/tilt/security/advisories/GHSA-6m68-r693-78qx"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-55883","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Deferred","weaknesses":["CWE-345"],"productCriteria":[],"sourceDates":{"published":"2026-07-10T22:16:44.287","lastModified":"2026-07-14T15:17:04.873"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
