From 1.8.0 until 1.19.4, the parseSubmission future API in packages/conform-dom/formdata.ts repeatedly scans FormData or URLSearchParams entries by each unique field name. An unauthenticated attacker can submit a crafted form containing many unique names, causing excessive synchronous CPU work and denial of service in an application that passes the submission to parseSubmission. Applications should continue to enforce request parsing limits before invoking Conform. This issue is fixed in version 1.19.4.","state":0,"publishedAt":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","score":8.7,"severity":null}],"references":["https://github.com/edmundhung/conform/security/advisories/GHSA-525m-7f82-2mf7","https://github.com/edmundhung/conform/commit/f9a1e696ef950efcada5f06ea2b202da505bf9b0","https://github.com/edmundhung/conform/releases/tag/v1.19.4"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-77679","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Sep 14, 2026, 5:14:08 PM","dateUpdated":"Sep 14, 2026, 7:01:26 PM"},"relatedAdvisories":[],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
