{"id":"CVE-2026-53649","aliases":["GHSA-xqhv-chqm-fhcc","GO-2026-5947"],"url":"https://o3.security/vulnerability/CVE-2026-53649","summary":"Joro: Unauthenticated Cross-Origin Plugin Upload Leads to RCE","details":"Joro is a web exploitation framework. Prior to version 1.1.1, Joro's default proxy mode exposes a local API on 127.0.0.1:9090 that performs no authentication and applies a wildcard CORS policy. Because plugin uploads use the CORS-safelisted multipart/form-data content type, cross-origin JavaScript on any page the operator visits can reach privileged endpoints - including uploading a native plugin and triggering a restart - directly through the operator's browser, with no preflight or credentials. Since plugins execute on load, this yields unauthenticated remote code execution as the operator's user from a single page visit. This issue has been patched in version 1.1.1.","published":"2026-09-02T17:21:39.908Z","modified":"2026-09-05T03:30:33.812085378Z","cvss":{"score":9.6,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H"},"epss":{"score":0.00215,"percentile":0.11778,"asOf":"2026-09-08"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/BishopFox/joro","fixedVersion":"0.0.0-20260601151442-5c0ca35db828"}],"fix":null,"references":[{"type":"WEB","url":"https://github.com/BishopFox/joro/releases/tag/1.1.1"},{"type":"ADVISORY","url":"https://github.com/BishopFox/joro/security/advisories/GHSA-xqhv-chqm-fhcc"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53649.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53649"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-05T03:30:33.812085378Z"}}
