The ApplyTemplate() function in models/attachment.go processes Office documents as ZIP archives and calls ioutil.ReadAll() on each contained file entry without enforcing size restrictions on uncompressed content, allowing a zip bomb payload to expand to several gigabytes in memory and cause the process to be terminated by the operating system.","state":0,"publishedAt":"2026-06-22T20:11:14.67+00:00","modifiedAt":"2026-10-08T15:22:32.489+00:00","affected":[{"ecosystem":"Vendor product","name":"gophish","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"defaultStatus\": \"affected\",\n                    \"packageURL\": \"pkg:golang/github.com/gophish/gophish\",\n                    \"vendor\": \"gophish\",\n                    \"product\": \"gophish\",\n                    \"repo\": \"https://github.com/gophish/gophish\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"versionType\": \"semver\",\n                            \"lessThanOrEqual\": \"0.12.1\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","score":7.1,"severity":"HIGH"},{"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/ashikmd7/GoPhish-0.12.1/blob/main/Unbounded%20Memory%20Allocation%20in%20Office%20Attachment%20Processing%20Leads%20to%20Server%20DoS/README.md","https://www.vulncheck.com/advisories/gophish-denial-of-service-via-office-document-upload"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-39904","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-39904","identifiers":["CVE-2026-39904"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
