{"id":"CVE-2026-54577","state":"PUBLISHED","title":"mport audit can inspect the wrong package when options are present","description":"mport is the MidnightBSD Package Manager. Prior to 2.7.8, the audit command in mport/mport.c computed option-adjusted local_argv and local_argc values but passed the original argument entry to audit_package(). When an operator or automation used an option such as -r before a package name, stale optind state and the unadjusted argument could cause mport to audit the option token instead of the requested package, producing a false-negative or useless result that could leave a vulnerable package unidentified. The corrected parsing resets optind and optreset before using the adjusted local arguments. This issue is fixed in version 2.7.8.","publishedAt":"2026-09-17T16:49:48.323Z","updatedAt":"2026-09-24T20:55:22.326Z","severity":{"score":2,"label":"Low","version":"4.0","vector":"CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["MidnightBSD mport"],"affected":[{"vendor":"MidnightBSD","product":"mport","versions":[{"version":"< 2.7.8","status":"affected"}]}],"references":["https://github.com/MidnightBSD/mport/security/advisories/GHSA-h3m9-vj4v-c35h","https://github.com/MidnightBSD/mport/pull/149","https://github.com/MidnightBSD/mport/commit/b897240dc8181c53fbee231e77f88657c1edb9a0","https://github.com/MidnightBSD/mport/releases/tag/2.7.8"],"weaknesses":["CWE-20","CWE-693"],"ingestedAt":"2026-10-29T20:12:24.861Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/54xxx/CVE-2026-54577.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-54577","state":"PUBLISHED","datePublished":"2026-09-17T16:49:48.323Z","dateUpdated":"2026-09-24T20:55:22.326Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-06-15T19:15:27.344Z"},"containers":{"cna":{"title":"mport audit can inspect the wrong package when options are present","descriptions":[{"lang":"en","value":"mport is the MidnightBSD Package Manager.
