{"cve":"CVE-2026-44895","nvd":{"published":"2026-05-26T22:16:42.730","modified":"2026-07-24T11:10:00.170","status":"Deferred","description":"GitLab MCP Server lets an AI agent talk directly to GitLab. Prior to 0.6.0, the HTTP transport in src/transport.ts ships with no authentication layer at all and a wildcard Access-Control-Allow-Origin: * on every response. The structural defect is that the SSE server stands up a stateful, mutation-capable RPC endpoint that is backed by the operator's GITLAB_PERSONAL_ACCESS_TOKEN without any inbound credential check, then advertises itself to every cross-origin browser context via the wildcard CORS header. The httpServer.listen(port) call at line 97 also passes no host argument, so the bind defaults to 0.0.0.0 and exposes the auth-less surface on every interface. This vulnerability is fixed in 0.6.0.","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","CWE-942"],"references":["https://github.com/yoda-digital/mcp-gitlab-server/security/advisories/GHSA-8jr5-6gvj-rfpf","https://github.com/yoda-digital/mcp-gitlab-server/security/advisories/GHSA-8jr5-6gvj-rfpf"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:36:28.938604137+00:00"},"epss":{"cve":"CVE-2026-44895","score":0.00445,"percentile":0.38758,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-8jr5-6gvj-rfpf","url":"https://osv.dev/vulnerability/GHSA-8jr5-6gvj-rfpf","summary":"@yoda.digital/gitlab-mcp-server's SSE transport has no authentication and wildcard CORS, exposing all 86 GitLab tools","modified":"2026-09-10T03:51:05.053995575Z","packages":[{"ecosystem":"npm","name":"@yoda.digital/gitlab-mcp-server","purl":"pkg:npm/%40yoda.digital/gitlab-mcp-server","ranges":["<0.6.0"],"fixed":["0.6.0"]}]}],"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).
