CVE-2026-61848
Description
A flaw was found in crass. This vulnerability allows a remote attacker to cause a Denial of Service (DoS) through excessive CPU resource consumption. When parsing input containing non-ASCII characters, inefficiencies in tracking the positions of multi-byte characters result in disproportionately long processing times. An attacker can exploit this issue by submitting specially crafted Cascading Style Sheets (CSS) input with many non-ASCII characters, causing the application to hang or become unresponsive.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
