CVE-2026-66062: Inefficient Regular Expression Complexity

SvelteKit is a framework for rapidly developing robust, performant web applications using Svelte. Prior to 2.70.2, the content negotiation header parser used by SvelteKit's request handling for headers such as Accept uses a regular expression vulnerable to quadratic backtracking, so a maliciously...

CVE-2026-68749 Quadratic regex backtracking in the html_sanitize_ex CSS scrubber allows CPU-exhaustion denial of service

Inefficient Regular Expression Complexity vulnerability in the CSS scrubber in rrrene htmlsanitizeex allows an unauthenticated remote attacker to exhaust server CPU via a long CSS declaration in sanitized HTML. The declaration regex in HtmlSanitizeEx.Scrubber.CSS.scrub/1 matches the property name...

CVE-2026-68749

The vulnerability CVE-2026-68749 affects the html_sanitize_ex Ruby gem (versions before 1.5.3; affected range includes 0.3.1–1.5.2). It stems from an inefficient greedy regex in HtmlSanitizeEx.Scrubber.CSS.scrub/1 that backtracks on long CSS declarations, causing quadratic CPU consumption and pot...
