HIGH

Uncontrolled recursion leads to abort in HTML serialization

Published April 27, 2019Updated November 8, 2023Source: osv

Summary

Affected versions of this crate did use recursion for serialization of HTML DOM trees. This allows an attacker to cause abort due to stack overflow by providing a pathologically nested input. The flaw was corrected by serializing the DOM tree iteratively instead.
