{"id":"CVE-2026-47110","summary":"Tiptap for PHP \u003c 2.1.1 DoS via Malformed href Attribute","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.","modified":"2026-08-12T03:51:10.549254672Z","published":"2026-06-24T21:21:39.655Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/47xxx/CVE-2026-47110.json","cna_assigner":"VulnCheck","cwe_ids":["CWE-241"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/47xxx/CVE-2026-47110.json"},{"type":"ADVISORY","url":"https://github.com/ueberdosis/tiptap-php/releases/tag/2.1.1"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-47110"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/tiptap-for-php-dos-via-malformed-href-attribute"},{"type":"REPORT","url":"https://github.com/ueberdosis/tiptap-php/pull/94"},{"type":"FIX","url":"https://github.com/ueberdosis/tiptap-php/commit/74bfb7be1c8c6102b240f3879b7f984a6ab87b97"},{"type":"PACKAGE","url":"https://github.com/ueberdosis/tiptap-php"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/ueberdosis/tiptap-php","events":[{"introduced":"0"},{"fixed":"74bfb7be1c8c6102b240f3879b7f984a6ab87b97"}],"database_specific":{"source":["AFFECTED_FIELD","DESCRIPTION","REFERENCES"],"extracted_events":[{"introduced":"0"},{"fixed":"2.1.1"}]}}],"versions":["2.1.0","2.0.0","1.4.0","1.3.0","1.2.0","1.1.0","1.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-47110.json"}}],"schema_version":"1.9.0","severity":[{"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"}]}
