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.","published":"2026-06-24T21:21:39.655Z","modified":"2026-10-21T02:58:14.031219007Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"ueberdosis/tiptap-php","fixedVersion":"2.1.1"}],"fix":{"url":"https://github.com/ueberdosis/tiptap-php/commit/74bfb7be1c8c6102b240f3879b7f984a6ab87b97","label":"ueberdosis/tiptap-php@74bfb7b"},"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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-21T02:58:14.031219007Z"}}
