Docmost is open-source collaborative wiki and documentation software. 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.
CVE-2026-65827
MEDIUMPre-NVD 6.56.5
EchelonGraph scoreLOW confidence
This medium-severity CVE scores 6.5 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit-prediction score not yet available (the EPSS model rescores nightly; freshly-published CVEs typically appear within 48 hours). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
