The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-109800 advisory. Element.findall and fully-consumed Element.iterfind exhibit On^2 time complexity when using XPath index predicates e.g. 1, last, last-N on XML documents with many...

CVE-2026-6879: Inefficient Algorithmic Complexity

Element.findall and fully-consumed Element.iterfind exhibit On^2 time complexity when using XPath index predicates e.g. 1, last, last-N on XML documents with many same-tag siblings. Element.find is only affected when the first match is near the end of the sibling list, such as with last or...

CVE-2026-13311

shell-quote prior to 1.8.5 finalizes parsed tokens in parse using Array.prototype.concat as a reduce accumulator, which reallocates and copies the entire growing array on every iteration. As a result parse runs in On^2 time relative to the number of input tokens. An attacker who can supply an...
