{"schema":"threatline.record/2","record":{"id":"CVE-2026-70406","aliases":["GHSA-m78w-jjjx-gp8r"],"summary":"Gitea private comparison disclosure with public-only tokens","details":"Gitea's shared comparison helper omits the token repository-access check used when updating pull requests. A public-only token with read:repository scope can route a comparison or pull request creation through a public base repository and retrieve commit history and diffs from a private head repository accessible to the token owner. This bypasses the token's public-only restriction; it does not remove the account's underlying repository permission checks.","categories":["Unclassified"],"product":"Gitea","vendor":"Gitea","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-70406","source_modified_at":"2026-10-14T15:03:17.796Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Gitea","vendor":"Gitea","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.27.2","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":6.5,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00341,"percentile":0.26449,"score_date":"2026-10-23"},"published_at":"2026-10-14T14:36:53.729Z","modified_at":"2026-10-14T15:03:17.796Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-70406","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-14T15:03:17.796Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-70406","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/go-gitea/gitea/security/advisories/GHSA-m78w-jjjx-gp8r","tags":["vendor-advisory"]},{"source":"CVE List","url":"https://blog.gitea.com/release-of-1.27.3/","tags":["release-notes"]},{"source":"CVE List","url":"https://github.com/go-gitea/gitea/pull/39006","tags":["patch"]},{"source":"CVE List","url":"https://github.com/go-gitea/gitea/pull/39013","tags":["patch"]},{"source":"CVE List","url":"https://github.com/go-gitea/gitea/releases/tag/v1.27.3","tags":["release-notes"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CISA ADP","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-14T14:54:29.357945Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-14T15:03:17.796Z","content_hash":"d66252c250dc36874dea3be666388b2135684abe4fe1392a5eb0cde208c946a1"}}
