{"schemaVersion":3,"id":"CVE-2026-112955","aliases":["GHSA-9g7p-m758-rp72"],"status":"published","duplicateOf":null,"title":null,"description":"ApostropheCMS is an open-source Node.js content management system. Prior to 3.7.1 of the import-export module, an authenticated importer can submit archives whose decompressed bytes, entry count, and entry sizes are not bounded before document-type authorization, and extraction or parsing failures can leave staging and extracted artifacts without unconditional cleanup. The already-hardened pre-authentication and write-error paths are separate, and current end-to-end denial-of-service impact from this residual path remains subject to maintainer validation. This issue is fixed in version 3.7.1.","dates":{"published":"2026-10-20T15:53:04.154Z","modified":"2026-10-20T15:53:04.154Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":6.5,"severity":"medium","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":6.5,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":6.5,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"OSV · Npm","score":6.5,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","exploitability":7.2,"impact":6,"computed":true}]},"epss":{"probability":0.00445,"percentile":0.37632,"severity":"low","asOf":"2026-10-21T00:00:00.000Z","change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[{"date":"2026-10-21T00:00:00.000Z","score":0.00445,"percentile":0.37632}],"last30":[{"date":"2026-10-21T00:00:00.000Z","score":0.00445,"percentile":0.37632}]},"kev":{"state":"not-listed","entries":[],"listedCount":0,"totalCatalogs":3,"catalogs":[{"source":"cisa","label":"CISA","listed":false,"entry":null},{"source":"enisa","label":"ENISA","listed":false,"entry":null},{"source":"circl","label":"CIRCL","listed":false,"entry":null}]},"ransomware":{"state":"none-recorded","sources":[]},"exploits":[],"exploitCount":0,"weaknesses":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption","description":"The product does not properly control the allocation and maintenance of a limited resource.","type":"weakness","status":"Draft","abstraction":"Class","likelihoodOfExploit":"High","url":"https://cwe.mitre.org/data/definitions/400.html"}],"affected":[{"vendor":"apostrophecms","product":"apostrophe","name":"apostrophe","label":"apostrophe","ecosystem":null,"cpePart":"a","purl":null,"purlType":null,"versions":[{"text":"< 4.34.0","noFixRecorded":false,"fixedIn":null}],"versionsText":"< 4.34.0","eol":null,"hubHref":"/vendor/apostrophecms/apostrophe"},{"vendor":"@apostrophecms","product":"import-export","name":"import-export","label":"import-export","ecosystem":null,"cpePart":"a","purl":null,"purlType":null,"versions":[{"text":"< 3.7.1","noFixRecorded":false,"fixedIn":null}],"versionsText":"< 3.7.1","eol":null,"hubHref":"/vendor/apostrophecms/import-export"},{"vendor":"@apostrophecms","product":"import-export","name":"@apostrophecms/import-export","label":"import-export","ecosystem":"Npm","cpePart":null,"purl":"pkg:npm/@apostrophecms/import-export","purlType":"npm","versions":[{"text":"< 3.7.1","noFixRecorded":false,"fixedIn":null}],"versionsText":"< 3.7.1","eol":null,"hubHref":null}],"affectedCount":3,"eol":{"hasEol":false,"count":0},"references":[{"url":"https://github.com/apostrophecms/apostrophe/security/advisories/GHSA-9g7p-m758-rp72","label":"github.com/apostrophecms/apostrophe/security/advisories/GHSA-9g7p-m758-rp72","hostname":"github.com","tags":["X Refsource CONFIRM","WEB"]},{"url":"https://github.com/apostrophecms/apostrophe/commit/06e4b377f3c360f9e89c32dccd7e505ad5ddf498","label":"github.com/apostrophecms/apostrophe/commit/06e4b377f3c360f9e89c32dccd7e505ad5ddf498","hostname":"github.com","tags":["X Refsource MISC","WEB"]},{"url":"https://github.com/apostrophecms/apostrophe/commit/40b989b1a9dd23d30029b8ce7668634265cfe5ea","label":"github.com/apostrophecms/apostrophe/commit/40b989b1a9dd23d30029b8ce7668634265cfe5ea","hostname":"github.com","tags":["X Refsource MISC","WEB"]},{"url":"https://github.com/apostrophecms/apostrophe/releases/tag/@apostrophecms/import-export@3.7.1","label":"github.com/apostrophecms/apostrophe/releases/tag/@apostrophecms/import-export@3.7.1","hostname":"github.com","tags":["X Refsource MISC","WEB"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-112955","label":"nvd.nist.gov/vuln/detail/CVE-2026-112955","hostname":"nvd.nist.gov","tags":["Advisory"]},{"url":"https://github.com/apostrophecms/apostrophe","label":"github.com/apostrophecms/apostrophe","hostname":"github.com","tags":["PACKAGE"]}],"lineage":{"upstream":[],"downstream":[],"duplicates":[],"related":[]},"timeline":[{"kind":"published","date":"2026-10-20T15:53:04.154Z","label":"Published","detail":"Vulnerability first disclosed.","source":null}],"risk":{"score":26,"level":"medium","profile":"Default","thresholds":{"critical":75,"high":50,"medium":25,"low":10}},"meta":{"dataAsOf":"2026-10-22T05:31:09.257Z","stale":false,"partial":false}}
