{"id":"CVE-2026-55884","aliases":["GHSA-c73q-8xxr-rgqm","GO-2026-5317"],"url":"https://o3.security/vulnerability/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.","published":"2026-07-10T21:36:18.861Z","modified":"2026-08-12T03:51:30.612414116Z","cvss":null,"epss":{"score":0.00496,"percentile":0.40295,"asOf":"2026-08-24"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/tilt-dev/tilt","fixedVersion":"0.37.4"}],"fix":{"url":"https://github.com/tilt-dev/tilt/commit/47393fba7f6ef5e305d5e814551feef8e4acbc0a","label":"tilt-dev/tilt@47393fb"},"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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:30.612414116Z"}}
