      "value": "@octokit/request sends parameterized requests to GitHub’s APIs with sensible defaults in browsers and Node. Starting in version 1.0.0 and prior to versions 9.2.1 and 8.4.1, the regular expression `/<([^>]+)>; rel=\"deprecation\"/` used to match the `link` header in HTTP responses is vulnerable to a ReDoS (Regular Expression Denial of Service) attack. This vulnerability arises due to the unbounded nature of the regex's matching behavior, which can lead to catastrophic backtracking when processing specially crafted input. An attacker could exploit this flaw by sending a malicious `link` header, resulting in excessive CPU usage and potentially causing the server to become unresponsive, impacting service availability. Versions 9.2.1 and 8.4.1 fix the issue."

A partir de la versión 1.0.0 y antes de la versión 9.2.1, la expresión regular `/&lt;([^&gt;]+)&gt;; rel=\"deprecation\"/` utilizada para hacer coincidir el encabezado `link` en las respuestas HTTP es vulnerable a un ataque ReDoS (denegación de servicio de expresión regular). Esta vulnerabilidad surge debido a la naturaleza ilimitada del comportamiento de coincidencia de la expresión regular, que puede provocar un retroceso catastrófico al procesar una entrada especialmente manipulada. Un atacante podría explotar esta falla enviando un encabezado `link` malicioso, lo que resultaría en un uso excesivo de la CPU y potencialmente causaría que el servidor dejara de responder, lo que afectaría la disponibilidad del servicio. La versión 9.2.1 corrige el problema."
