lib/common/html_re.js in remarkable 1.7.1 allows Regular Expression Denial of Service (ReDoS) via a CDATA section.

Weakness

The product uses a regular expression with an inefficient, possibly exponential worst-case computational complexity that consumes excessive CPU cycles.

Affected Software

Name Vendor Start Version End Version
Remarkable Remarkable_project 1.7.1 (including) 1.7.1 (including)

Extended Description

	  Attackers can create crafted inputs that
	  intentionally cause the regular expression to use
	  excessive backtracking in a way that causes the CPU
	  consumption to spike.
