Upgrading to `3.87.0` (or `4.0.0-canary.20` on the `4.x` line) is recommended.","state":0,"publishedAt":"2026-10-07T16:19:57+00:00","modifiedAt":"2026-10-07T16:30:06.3580441+00:00","affected":[{"ecosystem":"npm","name":"@payloadcms/db-mongodb","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"3.87.0"}]}],"versions":[],"rawVersionEvidence":null},{"ecosystem":"npm","name":"@payloadcms/db-mongodb","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"4.0.0-canary.0"},{"kind":"fixed","version":"4.0.0-canary.20"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V3","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:H/A:N","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"HIGH"}],"references":["https://github.com/payloadcms/payload/security/advisories/GHSA-4ww4-68q3-h7g5","https://nvd.nist.gov/vuln/detail/CVE-2026-106100","https://github.com/payloadcms/payload/commit/2a69863deb0e3c87e36c1b3b17ab2d5b02fcb941","https://github.com/payloadcms/payload/commit/8f77dffa9552885ec2710768cfee15b57e389935","https://github.com/payloadcms/payload","https://github.com/payloadcms/payload/releases/tag/v3.87.0"],"sourceUrl":"https://github.com/advisories/GHSA-4ww4-68q3-h7g5","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-4ww4-68q3-h7g5","identifiers":["GHSA-4ww4-68q3-h7g5","CVE-2026-106100"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
