The new link field introduced in Kirby 4 allows several different link types that each validate the entered link to the relevant URL format. It also includes a \"Custom\" link type for advanced use cases that don't fit any of the pre-defined link formats.  As the \"Custom\" link type is meant to be flexible, it also allows the javascript: URL scheme. In some use cases this can be intended, but it can also be misused by attackers to execute arbitrary JavaScript code when a user or visitor clicks on a link that is generated from the contents of the link field. This vulnerability is patched in 4.1.1.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N","score":5.4},"cwes":["CWE-79"],"references":["https://github.com/getkirby/kirby/commit/cda3dd9a15228d35e62ff86cfa87a67e7c687437","https://github.com/getkirby/kirby/security/advisories/GHSA-63h4-w25c-3qv4","https://github.com/getkirby/kirby/commit/cda3dd9a15228d35e62ff86cfa87a67e7c687437","https://github.com/getkirby/kirby/security/advisories/GHSA-63h4-w25c-3qv4"],"products":["getkirby:kirby"],"source":"nvd","synced_at":"2026-10-19T21:45:59.823092188+00:00"},"epss":{"cve":"CVE-2024-27087","score":0.00348,"percentile":0.28426,"date":"2026-11-01"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
