{"id":"CVE-2026-50162","summary":"oras-go: file store write outside workingDir via symlink traversal","details":"oras-go is a Go library for managing OCI artifacts. Prior to 2.6.1, resolveWritePath() in content/file/file.go uses a lexical filepath.Rel check for workingDir and does not account for symlink traversal, so when AllowPathTraversalOnWrite=false an attacker-controlled blob title through ocispec.AnnotationTitle such as out/pwn.txt can follow a workingDir symlink out -\u003e /some/outside/dir and cause pushFile() to create /some/outside/dir/pwn.txt outside workingDir. This issue is fixed in version 2.6.1.","aliases":["GHSA-8xwf-rjm4-xvhv","GO-2026-5879"],"modified":"2026-07-25T03:32:06.578631983Z","published":"2026-07-17T19:39:28.847Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-73"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/50xxx/CVE-2026-50162.json"},"references":[{"type":"WEB","url":"https://github.com/oras-project/oras-go/releases/tag/v2.6.1"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/50xxx/CVE-2026-50162.json"},{"type":"ADVISORY","url":"https://github.com/oras-project/oras-go/security/advisories/GHSA-8xwf-rjm4-xvhv"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-50162"},{"type":"FIX","url":"https://github.com/oras-project/oras-go/commit/cc323e564d90c6b5b4bdd71d3c8d2ee2713b37e5"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/oras-project/oras-go","events":[{"introduced":"0"},{"fixed":"cc323e564d90c6b5b4bdd71d3c8d2ee2713b37e5"},{"fixed":"47b7c804cb38a4af659ec735e473d3854c63a3c0"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"0"},{"fixed":"2.6.1"}]}}],"versions":["v2.6.0","v2.5.0","v2.4.0","v2.3.0","v2.2.0","v2.1.0","v2.0.2","v2.0.1","v2.0.0","v2.0.0-rc.6","v2.0.0-rc.5","v2.0.0-rc.4","v2.0.0-rc.3","v2.0.0-rc.2","v2.0.0-rc.1","v2.0.0-alpha","v0.5.0","v0.4.0","v0.3.0","v0.2.0","v0.1.0"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-50162.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N"}]}
