ETK-2026-2518Zero's internal tracking ID, independent of the CVE number.
validatedZero produced an exploit or a check.description
turbohtml versions 1.1.0 through 1.13.1 can consume excessive CPU while resolving XML namespace prefixes. An attacker who can supply XML to parsing, schema-compilation, or XML inner-HTML paths can stall the process, including other Python threads, with relatively small input.
mitigation
Upgrade turbohtml to version 1.14.0 or later. Until upgraded, restrict untrusted XML input and enforce input-size and processing limits on XML-handling paths.
fixed in 1.14.0
outcome
Contextual check: a technique exists and was validated, but no deterministic check could cover this one.
