{"cve":"CVE-2026-52812","nvd":{"published":"2026-06-24T21:16:57.223","modified":"2026-06-26T00:16:53.583","status":"Deferred","description":"Gogs is an open source self-hosted Git service. Prior to 0.14.3, Git LFS storage is content-addressed by OID alone (<LFS-root>/<oid[0]>/<oid[1]>/<oid>) but per-repo authorization lives in the lfs_object table keyed (repo_id, oid). serveUpload skips re-uploading when the OID file already exists on disk and inserts a new (repo_id, oid) row pointing at it without verifying the request body hashes to the OID being claimed. Any user with write access to one repo can bind their repo to an OID owned by a private repo and download the original bytes via their own download endpoint. This vulnerability is fixed in 0.14.3.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:L/SI:N/SA:N","score":7.1},"cvss_v3":null,"cwes":["CWE-345","CWE-639","CWE-862"],"references":["https://github.com/gogs/gogs/commit/f35a767af74e05342bafc6fdda02c791816426f8","https://github.com/gogs/gogs/pull/8333","https://github.com/gogs/gogs/releases/tag/v0.14.3","https://github.com/gogs/gogs/security/advisories/GHSA-6p9m-q3jp-47h4","https://github.com/gogs/gogs/security/advisories/GHSA-6p9m-q3jp-47h4"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:41:17.107060303+00:00"},"epss":{"cve":"CVE-2026-52812","score":0.00236,"percentile":0.14699,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-6p9m-q3jp-47h4","url":"https://osv.dev/vulnerability/GHSA-6p9m-q3jp-47h4","summary":"Gogs: LFS dedupe path leaks private repo content across tenants","modified":"2026-07-21T13:45:26.553627708Z","packages":[{"ecosystem":"Go","name":"gogs.io/gogs","purl":"pkg:golang/gogs.io/gogs","ranges":["<0.14.3"],"fixed":["0.14.3"]}]},{"id":"GO-2026-5184","url":"https://osv.dev/vulnerability/GO-2026-5184","summary":"Gogs: LFS dedupe path leaks private repo content across tenants in gogs.io/gogs","modified":"2026-06-25T19:45:12.714020634Z","packages":[{"ecosystem":"Go","name":"gogs.io/gogs","purl":"pkg:golang/gogs.io/gogs","ranges":["all versions"],"fixed":[]}]}],"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).
