{"id":"GHSA-4595-7fjw-r3jh","summary":"Tiptap contains an input validation vulnerability resulting in DoS","details":"Tiptap for PHP before version 2.1.1 contains an input validation vulnerability that allows authenticated attackers to cause a denial of service by submitting Tiptap JSON with the attrs.href field set to an array instead of a string, causing an unhandled TypeError in the Link::isAllowedUri() function when passed to preg_match(). Attackers can persist malformed JSON records that permanently crash the server-side HTML rendering pipeline for all subsequent viewers of that record until the database entry is manually repaired.","aliases":["CVE-2026-47110"],"modified":"2026-10-07T14:16:45.716820967Z","published":"2026-06-25T00:33:22Z","database_specific":{"nvd_published_at":"2026-06-24T22:16:47Z","cwe_ids":["CWE-241"],"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2026-10-07T14:01:58Z"},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-47110"},{"type":"WEB","url":"https://github.com/ueberdosis/tiptap-php/pull/94"},{"type":"WEB","url":"https://github.com/ueberdosis/tiptap-php/commit/74bfb7be1c8c6102b240f3879b7f984a6ab87b97"},{"type":"PACKAGE","url":"https://github.com/ueberdosis/tiptap-php"},{"type":"WEB","url":"https://github.com/ueberdosis/tiptap-php/releases/tag/2.1.1"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/tiptap-for-php-dos-via-malformed-href-attribute"}],"affected":[{"package":{"name":"ueberdosis/tiptap-php","ecosystem":"Packagist","purl":"pkg:composer/ueberdosis/tiptap-php"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.1.1"}]}],"versions":["1.0.0","1.1.0","1.2.0","1.3.0","1.4.0","2.0.0","2.1.0"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/06/GHSA-4595-7fjw-r3jh/GHSA-4595-7fjw-r3jh.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"},{"type":"CVSS_V4","score":"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"}]}
