{"id":"CVE-2026-28407","summary":"malcontent's nested archive extraction failure can drop content from scan inputs","details":"malcontent is software for discovering supply-chain compromises through context, differential analysis, and YARA. Prior to version 1.21.0, malcontent would remove nested archives which failed to extract which could potentially leave malicious content. A better approach is to preserve these archives so that malcontent can attempt a best-effort scan of the archive bytes. Version 1.21.0 fixes the issue.","aliases":["GHSA-945p-3jhm-6rcp","GO-2026-4577"],"modified":"2026-04-02T13:23:44.827359Z","published":"2026-02-27T21:28:06.258Z","related":["SUSE-SU-2026:1042-1"],"database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-703"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/28xxx/CVE-2026-28407.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/28xxx/CVE-2026-28407.json"},{"type":"ADVISORY","url":"https://github.com/chainguard-dev/malcontent/security/advisories/GHSA-945p-3jhm-6rcp"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-28407"},{"type":"FIX","url":"https://github.com/chainguard-dev/malcontent/commit/356c56659ccfcad0b249a97de8cf71f151ed3ee9"},{"type":"FIX","url":"https://github.com/chainguard-dev/malcontent/pull/1383"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/chainguard-dev/malcontent","events":[{"introduced":"0"},{"fixed":"d092575932e7d9b41c2507b7c1c4445c67f591fd"}]}],"versions":["v0.1.0","v0.10.0","v0.11.0","v0.12.0","v0.13.0","v0.13.1","v0.13.2","v0.14.0","v0.15.0","v0.15.1","v0.16.0","v0.16.1","v0.16.2","v0.17.0","v0.17.1","v0.18.0","v0.18.1","v0.18.2","v0.19.0","v0.2.0","v0.3.0","v0.4.0","v0.4.1","v0.5.0","v0.6.0","v0.7.0","v0.8.0","v0.9.0","v1.0.0","v1.0.1","v1.1.0","v1.1.1","v1.10.0","v1.10.1","v1.10.2","v1.10.3","v1.10.4","v1.11.0","v1.11.1","v1.11.2","v1.11.3","v1.12.0","v1.12.1","v1.12.2","v1.13.0","v1.13.1","v1.14.0","v1.14.1","v1.15.0","v1.15.1","v1.16.0","v1.16.1","v1.16.2","v1.16.3","v1.16.4","v1.16.5","v1.16.6","v1.17.0","v1.17.1","v1.17.2","v1.17.3","v1.17.4","v1.17.5","v1.18.0","v1.18.1","v1.18.2","v1.18.3","v1.19.0","v1.19.1","v1.19.2","v1.19.3","v1.19.4","v1.2.0","v1.20.0","v1.20.1","v1.20.2","v1.20.3","v1.20.4","v1.20.5","v1.3.0","v1.4.0","v1.5.0","v1.5.1","v1.6.0","v1.7.0","v1.7.1","v1.8.0","v1.8.1","v1.8.2","v1.8.3","v1.8.4","v1.8.5","v1.8.6","v1.8.7","v1.8.8","v1.9.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-28407.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"}]}
