{"cve":"CVE-2026-55884","nvd":{"published":"2026-07-10T22:16:44.423","modified":"2026-10-25T15:10:00.147","status":"Deferred","description":"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.","cvss_v4":{"vector":"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","score":9.2},"cvss_v3":null,"cwes":["CWE-306"],"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-c73q-8xxr-rgqm"],"products":[],"source":"nvd","synced_at":"2026-10-25T17:50:06.907763985+00:00"},"epss":{"cve":"CVE-2026-55884","score":0.00496,"percentile":0.42274,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-c73q-8xxr-rgqm","url":"https://osv.dev/vulnerability/GHSA-c73q-8xxr-rgqm","summary":"Tilt: Missing authentication on the network-exposed Tilt HUD server","modified":"2026-06-25T19:56:17.448713522Z","packages":[{"ecosystem":"Go","name":"github.com/tilt-dev/tilt","purl":"pkg:golang/github.com/tilt-dev/tilt","ranges":[">=0.20.8 <0.37.4"],"fixed":["0.37.4"]}]},{"id":"GO-2026-5317","url":"https://osv.dev/vulnerability/GO-2026-5317","summary":"Tilt: Missing authentication on the network-exposed Tilt HUD server in github.com/tilt-dev/tilt","modified":"2026-06-25T19:45:28.876892806Z","packages":[{"ecosystem":"Go","name":"github.com/tilt-dev/tilt","purl":"pkg:golang/github.com/tilt-dev/tilt","ranges":[">=0.20.8 <0.37.4"],"fixed":["0.37.4"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
