CVE-2026-68749: CWE-1333 Inefficient Regular Expression Complexity in rrrene html_sanitize_exCVE-2026-68749 0 CVE-2026-68749 is a high-severity vulnerability in the rrrene html_sanitize_ex library affecting versions from 0.3.1 up to but not including 1.5.3. It involves inefficient regular expression complexity in the CSS scrubber component, allowing an unauthenticated remote attacker to cause CPU exhaustion by sending a long CSS declaration in sanitized HTML. The vulnerability results in quadratic processing time due to a regex pattern that retries matching inefficiently on long runs of characters without a colon. The impact is limited to denial of service via CPU resource exhaustion; no data is disclosed or modified.
