CVE-2026-68749 is a high-severity vulnerability in the rrrene html_sanitize_ex library that causes inefficient regular expression complexity in its CSS scrubber. An unauthenticated remote attacker can exploit this by sending a long CSS declaration that triggers excessive CPU usage during HTML sanitization, leading to denial of service. The vulnerability arises from a regex pattern that matches property names greedily without length limits, causing quadratic time complexity. This results in CPU exhaustion but does not lead to data disclosure or modification. The affected versions are from 0.3.1 up to but not including 1.5.3, including 1.5.0-rc.0. No patch information is provided in the source data.
