High [CVE-2026-15308] CPU Denial of Service in HTML parser via repeated unterminated markup declarations
CVE-2026-15308Source published Source updated
The incremental HTML parser (html.parser.HTMLParser) allows for CPU denial-of-service through repeated unterminated markup declarations when processing uncontrolled data. A flaw was found in Python. Its incremental HTML parser can be exploited by a remote attacker. By sending specially crafted, uncontrolled data with repeated, incomplete markup declarations, the attacker can cause the system to consume excessive central processing unit (CPU) resources. This leads to a denial of service, making the affected system unresponsive. This Important vulnerability in Python's `html.parser.HTMLParser` can lead to a denial of service. Red Hat products utilizing this parser to process untrusted HTML content are susceptible to resource exhaustion. Red Hat severity: Important — CVSS 7.5…
