Prior to 0.14.3, an open redirect vulnerability exists in Gogs where attacker-controlled redirect_to parameters can bypass validation, allowing redirection to arbitrary external sites. All redirects in Gogs that are validated via the IsSameSite function are vulnerable. The function only inspects the first two characters of the URL string. This check fails to account for directory traversal sequences followed by backslashes. This vulnerability is fixed in 0.14.3.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N","score":5.4},"cwes":["CWE-601"],"references":["https://github.com/gogs/gogs/commit/c5da9631dc75f692f313373ae229c4d47ba6517f","https://github.com/gogs/gogs/pull/8322","https://github.com/gogs/gogs/releases/tag/v0.14.3","https://github.com/gogs/gogs/security/advisories/GHSA-xxhq-69mf-w8cr","https://github.com/gogs/gogs/security/advisories/GHSA-xxhq-69mf-w8cr"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:41:17.107060303+00:00"},"epss":{"cve":"CVE-2026-52802","score":0.00554,"percentile":0.46288,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-xxhq-69mf-w8cr","url":"https://osv.dev/vulnerability/GHSA-xxhq-69mf-w8cr","summary":"Gogs has an Open Redirect via redirect_to","modified":"2026-07-21T13:45:25.136410002Z","packages":[{"ecosystem":"Go","name":"gogs.io/gogs","purl":"pkg:golang/gogs.io/gogs","ranges":["<0.14.3"],"fixed":["0.14.3"]}]},{"id":"GO-2026-5773","url":"https://osv.dev/vulnerability/GO-2026-5773","summary":"Gogs has an Open Redirect via redirect_to in gogs.io/gogs","modified":"2026-06-25T23:01:17.154375339Z","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).
