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":"2026-06-22T21:31:00+00:00","modifiedAt":"2026-08-18T15:10:30.4264362+00:00","affected":[{"ecosystem":"Go","name":"github.com/gophish/gophish","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"last_affected","version":"0.12.1"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V3","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":null,"severity":null},{"system":"CVSS_V4","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":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"HIGH"}],"references":["https://nvd.nist.gov/vuln/detail/CVE-2026-39904","https://github.com/ashikmd7/GoPhish-0.12.1/blob/main/Unbounded%20Memory%20Allocation%20in%20Office%20Attachment%20Processing%20Leads%20to%20Server%20DoS/README.md","https://github.com/gophish/gophish","https://www.vulncheck.com/advisories/gophish-denial-of-service-via-office-document-upload"],"sourceUrl":"https://github.com/advisories/GHSA-42jc-v69j-g38f","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-42jc-v69j-g38f","identifiers":["GHSA-42jc-v69j-g38f","CVE-2026-39904","GO-2026-6212"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
