Summary

rubygem-nokogiri security update

Details

Nokogiri parses and searches XML/HTML very quickly, and also has correctly implemented CSS3 selector support as well as XPath support. Nokogiri also features an Hpricot compatibility layer to help ease the change to using correct CSS and XPath.

Security Fix(es):

Nokogiri is an open source XML and HTML library for Ruby. Nokogiri less than v1.13.4 contains an inefficient regular expression that is susceptible to excessive backtracking when attempting to detect encoding in HTML documents. Users are advised to upgrade to Nokogiri >= 1.13.4. There are no known workarounds for this issue.(CVE-2022-24836)

Severity

9.8 (Critical)

Detection rules are retrieved from Rulezet.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
