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
