CVE-2026-57435 (opens in a new tab)How to fix?
Upgrade nokogiri to version 1.19.4 or higher.
Overview
Affected versions of this package are vulnerable to Expired Pointer Dereference when replacing an XML attribute's value via value= or content= after previously accessing the attribute's child node. An attacker can cause invalid memory access or application crashes by manipulating attribute values and child nodes in a specific sequence.
Note: This is only exploitable if the application directly accesses an attribute's child node and then mutates the same attribute's value without intervening safeguards.
Workaround
This vulnerability can be mitigated by avoiding direct access to attribute child nodes before mutating the same attribute's value.
