{"cve":"CVE-2026-44985","nvd":{"published":"2026-05-26T22:16:43.587","modified":"2026-07-24T12:10:00.210","status":"Analyzed","description":"Dozzle is a realtime log viewer for docker containers. Prior to 10.5.2, he WebSocket upgrader for the /exec and /attach endpoints uses CheckOrigin: func(r *http.Request) bool { return true }, accepting upgrade requests from any origin. Combined with the JWT cookie using SameSite: Lax, this enables Cross-Site WebSocket Hijacking (CSWSH). An attacker hosting a page on a same-site origin (e.g., a sibling subdomain, or another service on localhost) can initiate a WebSocket connection to the exec endpoint that carries the victim's valid JWT cookie, gaining interactive shell access in any container the victim is authorized to access. This vulnerability is fixed in 10.5.2.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N","score":8.7},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H","score":9.6},"cwes":["CWE-346"],"references":["https://github.com/amir20/dozzle/releases/tag/v10.5.2","https://github.com/amir20/dozzle/security/advisories/GHSA-j643-x8pv-8m67","https://github.com/amir20/dozzle/security/advisories/GHSA-j643-x8pv-8m67"],"products":["amirraminfar:dozzle"],"source":"nvd","synced_at":"2026-10-19T22:36:28.938604137+00:00"},"epss":{"cve":"CVE-2026-44985","score":0.00209,"percentile":0.11145,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-j643-x8pv-8m67","url":"https://osv.dev/vulnerability/GHSA-j643-x8pv-8m67","summary":"Dozzle's Cross-Site WebSocket Hijacking (CSWSH) on exec/attach endpointsbypasses authentication","modified":"2026-06-25T23:11:43.528516296Z","packages":[{"ecosystem":"Go","name":"github.com/amir20/dozzle","purl":"pkg:golang/github.com/amir20/dozzle","ranges":["<=10.5.1"],"fixed":[]}]},{"id":"GO-2026-5449","url":"https://osv.dev/vulnerability/GO-2026-5449","summary":"Dozzle's Cross-Site WebSocket Hijacking (CSWSH) on exec/attach endpointsbypasses authentication in github.com/amir20/dozzle","modified":"2026-06-25T23:01:14.563568268Z","packages":[{"ecosystem":"Go","name":"github.com/amir20/dozzle","purl":"pkg:golang/github.com/amir20/dozzle","ranges":["all versions"],"fixed":[]}]}],"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).
