  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2024-7592
There is a LOW severity vulnerability affecting CPython, specifically the 'http.cookies' standard library module. When parsing cookies that contained backslashes for quoted characters in the cookie value, the parser would use an algorithm with quadratic complexity, resulting in excess CPU resources being used while parsing the value.

Summary
  • (es) Existe una vulnerabilidad de gravedad BAJA que afecta a CPython, específicamente al módulo de librería estándar 'http.cookies'. Al analizar cookies que contenían barras invertidas para caracteres entrecomillados en el valor de la cookie, el analizador usaría un algoritmo con complejidad cuadrática, lo que resultaría en un exceso de recursos de CPU que se usarían al analizar el valor.
