ETK-2026-2520Zero's internal tracking ID, independent of the CVE number.
waiting for further signalsZero needs more public information before it can validate it.description
turbohtml versions 1.0.0 through 1.13.1 mishandle certain invalid JavaScript inputs during minification. An attacker may crash a service that processes untrusted JavaScript, or untrusted HTML with JavaScript minification enabled; the reported out-of-bounds read does not place read bytes in output.
mitigation
Upgrade turbohtml to version 1.14.0 or later. Until upgraded, avoid minifying untrusted JavaScript and disable JavaScript minification for untrusted HTML where feasible.
fixed in 1.14.0
outcome
Contextual: an exploit technique exists, but no deterministic check could cover this one.
