From 0.21.0 until 0.95.0, any authenticated workspace member with edit rights to a space can upload an archive to the page-import feature whose ZIP extraction routine does not limit total uncompressed size, per-entry size, or entry count. The extractor writes entries to the server temp directory and automatically extracts one nested ZIP, allowing an outer upload within the default 200 MB limit to expand by multiple GB. The resulting disk exhaustion can crash the import worker and degrade or take down the instance for all tenants. This issue is fixed in version 0.95.0.","state":0,"publishedAt":"2026-09-24T18:28:36.809+00:00","modifiedAt":"2026-09-24T19:22:12.94+00:00","affected":[{"ecosystem":"Vendor product","name":"docmost","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"docmost\",\n                    \"product\": \"docmost\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 0.21.0, < 0.95.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":6.5,"severity":"MEDIUM"}],"references":["https://github.com/docmost/docmost/security/advisories/GHSA-frjw-66gr-799m","https://github.com/docmost/docmost/commit/04110884b4e90a43cc5b337e063d0b7493be5da7","https://github.com/docmost/docmost/releases/tag/v0.95.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-65827","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-65827","identifiers":["CVE-2026-65827"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
