Prior to 0.26.3, the identified vulnerability allows creating or deleting an object via the APIExport VirtualWorkspace in any arbitrary target workspace for pre-existing resources. By design, this should only be allowed when the workspace owner decides to give access to an API provider by creating an APIBinding. With this vulnerability, it is possible for an attacker to create and delete objects even if none of these requirements are satisfied, i.e. even if there is no APIBinding in that workspace at all or the workspace owner has created an APIBinding, but rejected a permission claim. A fix for this issue has been identified and has been published with kcp 0.26.3 and 0.27.0.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:N","score":9.6},"cwes":["CWE-285"],"references":["https://github.com/kcp-dev/kcp/commit/614ecbf35f11db00f65391ab6fbb1547ca8b5d38","https://github.com/kcp-dev/kcp/pull/3338","https://github.com/kcp-dev/kcp/security/advisories/GHSA-w2rr-38wv-8rrp"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:00:28.034033815+00:00"},"epss":{"cve":"CVE-2025-29922","score":0.00377,"percentile":0.31686,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-w2rr-38wv-8rrp","url":"https://osv.dev/vulnerability/GHSA-w2rr-38wv-8rrp","summary":"kcp allows unauthorized creation and deletion of objects in arbitrary workspaces through APIExport Virtual Workspace","modified":"2025-03-25T20:22:07.507783Z","packages":[{"ecosystem":"Go","name":"github.com/kcp-dev/kcp","purl":"pkg:golang/github.com/kcp-dev/kcp","ranges":["<0.26.3"],"fixed":["0.26.3"]}]},{"id":"GO-2025-3538","url":"https://osv.dev/vulnerability/GO-2025-3538","summary":"kcp allows unauthorized creation and deletion of objects in arbitrary workspaces through APIExport Virtual Workspace in github.com/kcp-dev/kcp","modified":"2026-03-03T04:56:25.483045Z","packages":[{"ecosystem":"Go","name":"github.com/kcp-dev/kcp","purl":"pkg:golang/github.com/kcp-dev/kcp","ranges":["<0.26.3"],"fixed":["0.26.3"]}]}],"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).
