{"id":"AZL-95487","summary":"CVE-2026-71557 affecting package packer 1.9.5-18","details":"go-git is an extensible git implementation library written in pure Go. Prior to 5.19.2 and 6.0.0-alpha.5, reference names are not sanitized before being used to construct on-disk paths under the reference storage directory, so a maliciously crafted reference name (for example containing directory-traversal sequences) can cause go-git to write files outside the intended reference storage directory. Versions 5.19.2 and 6.0.0-alpha.5 fix the issue.","modified":"2026-08-30T05:26:50Z","published":"2026-08-07T17:17:10Z","upstream":["CVE-2026-71557"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-71557"}],"affected":[{"package":{"name":"packer","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/packer"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"1.9.5-18"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-95487.json"}}],"schema_version":"1.9.0"}
