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."}],"affected":[{"source":"security-advisories@github.com","affectedData":[{"vendor":"apostrophecms","product":"apostrophe","versions":[{"version":"< 4.34.0","status":"affected"}]},{"vendor":"@apostrophecms","product":"import-export","versions":[{"version":"< 3.7.1","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","baseScore":6.5,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":2.8,"impactScore":3.6}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Primary","description":[{"lang":"en","value":"CWE-400"}]}],"references":[{"url":"https://github.com/apostrophecms/apostrophe/commit/06e4b377f3c360f9e89c32dccd7e505ad5ddf498","source":"security-advisories@github.com"},{"url":"https://github.com/apostrophecms/apostrophe/commit/40b989b1a9dd23d30029b8ce7668634265cfe5ea","source":"security-advisories@github.com"},{"url":"https://github.com/apostrophecms/apostrophe/releases/tag/@apostrophecms/import-export@3.7.1","source":"security-advisories@github.com"},{"url":"https://github.com/apostrophecms/apostrophe/security/advisories/GHSA-9g7p-m758-rp72","source":"security-advisories@github.com"}]}
