{"cve":"CVE-2022-41925","nvd":{"published":"2022-11-23T19:15:12.487","modified":"2026-06-17T05:04:04.467","status":"Modified","description":"A vulnerability identified in the Tailscale client allows a malicious website to access the peer API, which can then be used to access Tailscale environment variables. In the Tailscale client, the peer API was vulnerable to DNS rebinding. This allowed an attacker-controlled website visited by the node to rebind DNS for the peer API to an attacker-controlled DNS server, and then making peer API requests in the client, including accessing the node’s Tailscale environment variables. An attacker with access to the peer API on a node could use that access to read the node’s environment variables, including any credentials or secrets stored in environment variables. This may include Tailscale authentication keys, which could then be used to add new nodes to the user’s tailnet. The peer API access could also be used to learn of other nodes in the tailnet or send files via Taildrop. All Tailscale clients prior to version v1.32.3 are affected. Upgrade to v1.32.3 or later to remediate the issue.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H","score":8.8},"cwes":["CWE-352"],"references":["https://emily.id.au/tailscale","https://github.com/tailscale/tailscale/security/advisories/GHSA-qccm-wmcq-pwr6","https://tailscale.com/security-bulletins/#ts-2022-005","https://emily.id.au/tailscale","https://github.com/tailscale/tailscale/security/advisories/GHSA-qccm-wmcq-pwr6"],"products":["tailscale:tailscale"],"source":"nvd","synced_at":"2026-10-19T21:37:28.463369388+00:00"},"epss":{"cve":"CVE-2022-41925","score":0.00566,"percentile":0.46971,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-qccm-wmcq-pwr6","url":"https://osv.dev/vulnerability/GHSA-qccm-wmcq-pwr6","summary":"Tailscale daemon is vulnerable to information disclosure via CSRF","modified":"2024-08-21T16:28:57.767895Z","packages":[{"ecosystem":"Go","name":"tailscale.com/cmd","purl":"pkg:golang/tailscale.com/cmd","ranges":["<1.32.3"],"fixed":["1.32.3"]}]},{"id":"GO-2022-1119","url":"https://osv.dev/vulnerability/GO-2022-1119","summary":"Tailscale daemon is vulnerable to information disclosure via CSRF in tailscale.com","modified":"2026-03-03T04:52:44.788252Z","packages":[{"ecosystem":"Go","name":"tailscale.com","purl":"pkg:golang/tailscale.com","ranges":["<1.32.3"],"fixed":["1.32.3"]}]}],"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).
