- Affected
- Packagist ueberdosis/tiptap-php < 2.1.1
- Fixed in
- 2.1.1· Vendor fix available
- Issue
- 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 pregmatch(). 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.
Recommended action: Upgrade to 2.1.1 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
