CVE-2022-29181

Estado: ModificadaAlta (8.2)—

Nokogiri es una biblioteca XML y HTML de código abierto para Ruby. En versiones anteriores a 1.13.6, Nokogiri no comprobaba todas las entradas en los analizadores SAX de XML y HTML4, lo que permitía que entradas no confiables especialmente diseñadas causaran errores de acceso a memoria ilegales (segfault) o lecturas de memoria no relacionadas. La versión 1.13.6 contiene un parche para este problema. Como mitigación, asegúrese de que la entrada no confiable es una "String" llamando a "#to_s" o su equivalente

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
