In affected versions when the application being run by linkerd is susceptible to SSRF, an attacker could potentially trigger a denial-of-service (DoS) attack by making requests to localhost:4191/shutdown. Linkerd could introduce an optional environment variable to control a token that must be passed as a header. Linkerd should reject shutdown requests that do not include this header. This issue has been addressed in release version edge-24.6.2 and all users are advised to upgrade. There are no known workarounds for this vulnerability.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L","score":3.7},"cwes":["CWE-918"],"references":["https://github.com/linkerd/linkerd2-proxy/blob/46957de49f25fd4661af7b7c52659148f4d6dd27/linkerd/app/admin/src/server.rs","https://github.com/linkerd/linkerd2/commit/35fb2d6d11ef6520ae516dd717790529f85224fa","https://github.com/linkerd/linkerd2/security/advisories/GHSA-6v94-gj6x-jqj7","https://github.com/linkerd/linkerd2-proxy/blob/46957de49f25fd4661af7b7c52659148f4d6dd27/linkerd/app/admin/src/server.rs","https://github.com/linkerd/linkerd2/commit/35fb2d6d11ef6520ae516dd717790529f85224fa"],"products":[],"source":"nvd","synced_at":"2026-10-19T21:52:42.518321223+00:00"},"epss":{"cve":"CVE-2024-40632","score":0.00444,"percentile":0.38671,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GO-2024-2984","url":"https://osv.dev/vulnerability/GO-2024-2984","summary":"Linkerd potential access to the shutdown endpoint in github.com/linkerd/linkerd2","modified":"2025-10-15T11:42:28.655831Z","packages":[{"ecosystem":"Go","name":"github.com/linkerd/linkerd2","purl":"pkg:golang/github.com/linkerd/linkerd2","ranges":["<0.5.1-0.20240614165515-35fb2d6d11ef"],"fixed":["0.5.1-0.20240614165515-35fb2d6d11ef"]}]}],"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).
