Prior to 2.42.3 and 2.40.3, a bug in the GRPC authorization middleware of the \"Reva\" component of OpenCloud allows a malicious user to bypass the scope verification of a public link. By exploiting this via the the \"archiver\" service this can be leveraged to create an archive (zip or tar-file) containing all resources that this creator of the public link has access to. This vulnerability is fixed in 2.42.3 and 2.40.3.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","score":8.1},"cwes":["CWE-863"],"references":["https://github.com/opencloud-eu/reva/commit/95aa2bc5d980eaf6cc134d75782b4f5ac7b36ae1","https://github.com/opencloud-eu/reva/security/advisories/GHSA-9j2f-3rj3-wgpg"],"products":["heinlein:opencloud_reva"],"source":"nvd","synced_at":"2026-10-19T22:22:27.261130201+00:00"},"epss":{"cve":"CVE-2026-23989","score":0.00304,"percentile":0.2323,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-9j2f-3rj3-wgpg","url":"https://osv.dev/vulnerability/GHSA-9j2f-3rj3-wgpg","summary":"OpenCloud Reva has a Public Link Exploit","modified":"2026-02-19T20:41:16.163826Z","packages":[{"ecosystem":"Go","name":"github.com/opencloud-eu/reva/v2","purl":"pkg:golang/github.com/opencloud-eu/reva/v2","ranges":["<2.40.3"],"fixed":["2.40.3"]},{"ecosystem":"Go","name":"github.com/opencloud-eu/reva/v2","purl":"pkg:golang/github.com/opencloud-eu/reva/v2","ranges":[">=2.41.0 <2.42.3"],"fixed":["2.42.3"]}]},{"id":"GO-2026-4444","url":"https://osv.dev/vulnerability/GO-2026-4444","summary":"OpenCloud Reva has a Public Link Exploit in github.com/opencloud-eu/reva","modified":"2026-02-19T20:41:16.163826Z","packages":[{"ecosystem":"Go","name":"github.com/opencloud-eu/reva","purl":"pkg:golang/github.com/opencloud-eu/reva","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"github.com/opencloud-eu/reva/v2","purl":"pkg:golang/github.com/opencloud-eu/reva/v2","ranges":["<2.40.3",">=2.41.0 <2.42.3"],"fixed":["2.40.3","2.42.3"]}]}],"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).
