Apko prior to version 1.2.9, corresponding to melange prior to version 0.50.4, verified the control section hash (`.PKGINFO` etc.) against the signed `APKINDEX`, but never verified the data section hash (the actual package files that get installed). An attacker who could compromise a mirror, poison a cache, or MITM a package fetch could substitute arbitrary file contents while the control hash check still passed. Apko version 1.2.9 and melange version 0.50.4 contain a fix.","state":0,"publishedAt":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H","score":8.3,"severity":null}],"references":["https://github.com/chainguard-dev/melange/security/advisories/GHSA-fpg8-7664-jc5q"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-76767","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Sep 11, 2026, 9:05:30 PM","dateUpdated":"Sep 14, 2026, 4:19:01 PM"},"relatedAdvisories":[{"id":"openSUSE-SU-2026:11829-1","title":"apko-1.4.4-1.1 on GA media","vulnerabilityIds":["CVE-2026-54174"]}],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
