Attackers can place a crafted package under the prime-mover-export-files directory so that the malicious value renders unescaped in the column_site_title() method of PrimeMoverBackupMenuListTable.php, triggering script execution in an administrator's browser when they view the Prime Mover Packages list table without needing to restore the package.","categories":["Unclassified"],"product":"Prime Mover","vendor":"Codexonics","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-101890","source_modified_at":"2026-10-01T21:44:58.019Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"Prime Mover","vendor":"Codexonics","versions":[{"status":"affected","version":"0","versionType":"semver","lessThan":"2.2.1"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-101890","source_modified_at":"2026-10-01T21:44:58.019Z","fetched_at":"2026-10-23T18:52:38.922436Z","package":{"name":"Prime Mover","ecosystem":null},"version":"2.2.1","basis":"first unaffected version stated in the CVE record"}],"cvss":5.1,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00163,"percentile":0.05225,"score_date":"2026-10-23"},"published_at":"2026-10-01T16:22:08.087Z","modified_at":"2026-10-01T21:44:58.019Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-101890","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-10-01T21:44:58.019Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-101890","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://wordpress.org/plugins/prime-mover/#developers","tags":["release-notes","patch"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/prime-mover-stored-xss-via-package-metadata","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-01T18:07:43.250398Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-01T21:44:58.019Z","content_hash":"17c84b3eb3699a845c4194bc146336c2cdec4e0513a22b9d3342930edc8f710b"}}
