{"id":"CVE-2026-55884","summary":"Tilt: Missing authentication on the network-exposed Tilt HUD server","details":"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.","aliases":["GHSA-c73q-8xxr-rgqm","GO-2026-5317"],"modified":"2026-07-14T03:55:51.285336977Z","published":"2026-07-10T21:36:18.861Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-306"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/55xxx/CVE-2026-55884.json"},"references":[{"type":"WEB","url":"https://github.com/tilt-dev/tilt/releases/tag/v0.37.4"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/55xxx/CVE-2026-55884.json"},{"type":"ADVISORY","url":"https://github.com/tilt-dev/tilt/security/advisories/GHSA-c73q-8xxr-rgqm"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-55884"},{"type":"FIX","url":"https://github.com/tilt-dev/tilt/commit/47393fba7f6ef5e305d5e814551feef8e4acbc0a"},{"type":"FIX","url":"https://github.com/tilt-dev/tilt/pull/6776"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/tilt-dev/tilt","events":[{"introduced":"640fd1bdce052755388446d776e31de5ff7199e2"},{"fixed":"0b591662e013ba2d551d4861009d7b3c2276c90e"}],"database_specific":{"extracted_events":[{"introduced":"0.20.8"},{"fixed":"0.37.4"}],"source":"AFFECTED_FIELD"}}],"versions":["v0.37.3","v0.37.2","v0.37.1","v0.37.0","v0.36.3","v0.36.2","v0.36.1","v0.36.0","v0.35.2","v0.35.1","v0.35.0","v0.34.5","v0.34.4","v0.34.3","v0.34.2","v0.34.1","v0.34.0","v0.33.22","v0.33.21","v0.33.20","v0.33.19","v0.33.18","v0.33.17","v0.33.16","v0.33.15","v0.33.14","v0.33.13","v0.33.12","v0.33.11","v0.33.10","v0.33.9","v0.33.8","v0.33.7","v0.33.6","v0.33.5","v0.33.4","v0.33.3","v0.33.2","v0.33.1","v0.33.0","v0.32.4","v0.32.3","v0.32.2","v0.32.1","v0.32.0","v0.31.2","v0.31.1","v0.31.0","v0.30.13","v0.30.12","v0.30.11","v0.30.10","v0.30.9","v0.30.8","v0.30.7","v0.30.6","v0.30.5","v0.30.4","v0.30.3","v0.30.2","v0.30.1","v0.30.0","v0.29.0","v0.28.1","v0.28.0","v0.27.3","v0.27.2","v0.27.1","v0.27.0","v0.26.3","v0.26.2","v0.26.1","v0.26.0","v0.25.3","v0.25.2","v0.25.1","v0.25.0","v0.24.0","v0.23.9","v0.23.8","v0.23.7","v0.23.6","v0.23.5","v0.23.4","v0.23.3","v0.23.2","v0.23.1","v0.23.0","v0.22.15","v0.22.14","v0.22.13","v0.22.12","v0.22.11","v0.22.10","v0.22.9","v0.22.8","v0.22.7","v0.22.6","v0.22.5","v0.22.4","v0.22.3","v0.22.2","v0.22.1","v0.22.0","v0.21.3","v0.21.1","v0.21.0","v0.20.9","v0.20.8"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-55884.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:L/SC:N/SI:N/SA:N"}]}
