@tiptap/core is vulnerable to Regular Expression Denial of Service (ReDoS)
53
Medium Risk
This Affects:
@tiptap/coreTL;DR
The @tiptap/core Markdown attribute parsers use unanchored regular expressions when reading Pandoc-style block attributes and inline shortcode attributes. Crafted Markdown input with repeated prefixes and no closing quoted value or equals sign triggers quadratic backtracking, leading to Denial of Service. The fix anchors and bounds the attribute matching expressions to remove the backtracking.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and your application parses untrusted or Markdown content.
