A use after free issue discovered in ONLYOFFICE DocumentServer 4.0.3 through 7.3.2 allows remote attackers to run arbitrary code via crafted JavaScript file.
Security readout for executives and security teams
CVE-2023-30186 is a memory-safety flaw in ONLYOFFICE DocumentServer. Public CVE text says versions 4.0.3 through 7.3.2 can allow remote attackers to run arbitrary code using a crafted JavaScript file. This matters most where the server processes untrusted or externally supplied documents/content. Organizations using ONLYOFFICE DocumentServer versions 4.0.3 through 7.3.2 are the stated exposed population. Risk is higher if DocumentServer is internet-accessible or processes files/content from untrusted users. The supplied affected-product metadata is incomplete, so confirm against deployed ONLYOFFICE components. Prioritize assessment where ONLYOFFICE handles external documents or user-supplied content. Remote code execution can threaten document infrastructure and connected data. Because CVSS and exploitation evidence are absent, treat as high urgency while confirming actual deployment exposure. Mitigation focus: Inventory ONLYOFFICE DocumentServer deployments and identify versions 4.0.3 through 7.3.2.; Review ONLYOFFICE guidance and upgrade to a vendor-supported fixed release.; Use the referenced upstream fix only through approved, tested vendor packages or builds..
