From 0.145.0 until 0.146.0, openapi3filter repeatedly calls regexp.MustCompile for the same parameter-name regular expression inside the per-query-key loop in urlValuesDecoder.DecodeObject used to decode a deepObject query parameter. An unauthenticated remote client can send an affected endpoint a request containing many unrelated query keys, causing ValidateRequest to perform work and allocations proportional to the attacker-controlled key count for every deepObject parameter. The expression itself is fixed and this is not regular expression denial of service; the resource consumption comes from loop-invariant recompilation. This issue is fixed in version 0.146.0.","state":0,"publishedAt":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","score":5.3,"severity":null}],"references":["https://github.com/getkin/kin-openapi/security/advisories/GHSA-h4r5-mxv5-8mjc","https://github.com/getkin/kin-openapi/commit/d090e36b2f1c42c898ba2a687a8f6e25f5ca727f","https://github.com/getkin/kin-openapi/releases/tag/v0.146.0"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-102158","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Oct 15, 2026, 3:37:19 PM","dateUpdated":"Oct 15, 2026, 6:32:57 PM"},"relatedAdvisories":[{"id":"openSUSE-SU-2026:12164-1","title":"hugo-0.168.0-2.1 on GA media","vulnerabilityIds":["CVE-2026-100347","CVE-2026-100348","CVE-2026-100349","CVE-2026-100350","CVE-2026-100351","CVE-2026-100352"]},{"id":"RHSA-2026:76677","title":"Red Hat Security Advisory: Red Hat Hardened Images RPMs bug fix and enhancement update","vulnerabilityIds":["CVE-2024-24786","CVE-2026-56851","CVE-2026-61801","CVE-2026-95502","CVE-2026-97394","CVE-2026-100347","CVE-2026-100348","CVE-2026-100349","CVE-2026-100350","CVE-2026-100351","CVE-2026-101899","CVE-2026-109855"]},{"id":"RHSA-2026:82637","title":"Red Hat Security Advisory: Red Hat Hardened Images RPMs bug fix and enhancement update","vulnerabilityIds":["CVE-2026-97394","CVE-2026-100347","CVE-2026-100348","CVE-2026-100349","CVE-2026-100350","CVE-2026-100351","CVE-2026-100352","CVE-2026-100353","CVE-2026-100354"]}],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
