That copy did not check whether the user may read the base repository's code. A user who had forked a repository and later lost access to it, for example after it was made private or they were removed as a collaborator, could keep copying its current branches into their fork and read them. The copy now requires read access to the code of the base repository."}], "affected": [{"vendor": "Gitea", "product": "Gitea", "packageName": "gitea.dev", "defaultStatus": "unaffected", "versions": [{"version": "1.25.0", "status": "affected", "lessThan": "28.4.0", "versionType": "semver"}]}], "references": [{"url": "https://github.com/go-gitea/gitea/security/advisories/GHSA-9vh6-6hgj-j5m5", "name": "GitHub Security Advisory GHSA-9vh6-6hgj-j5m5", "tags": ["vendor-advisory"]}, {"url": "https://github.com/go-gitea/gitea/pull/40131", "name": "Fix: go-gitea/gitea pull request #40131", "tags": ["patch"]}, {"url": "https://github.com/go-gitea/gitea/pull/40281", "name": "Fix backport to release/v28: go-gitea/gitea pull request #40281", "tags": ["patch"]}, {"url": "https://blog.gitea.com/release-of-28.4.0/", "name": "Gitea 28.4.0 release announcement", "tags": ["release-notes"]}, {"url": "https://github.com/go-gitea/gitea/releases/tag/v28.4.0", "name": "go-gitea/gitea v28.4.0 release", "tags": ["release-notes"]}], "problemTypes": [{"descriptions": [{"lang": "en", "type": "CWE", "cweId": "CWE-284", "description": "CWE-284: Improper Access Control"}, {"lang": "en", "type": "CWE", "cweId": "CWE-863", "description": "CWE-863: Incorrect Authorization"}]}], "credits": [{"lang": "en", "value": "https://github.com/adamyordan", "type": "reporter"}, {"lang": "en", "value": "https://github.com/silverwind", "type": "remediation developer"}]}}}
