The report released on Friday detailed a litany of alleged atrocities, including killings, sexual crimes and the forced displacement of civilians.
"Violence involves incredibly brutal attacks on communities," said commission chairperson Yasmin Sooka, highlighting the severity of the situation.
Sooka pointed out the "escalating abduction of women and children" and stressed the need for urgent action to address the rights violations.
Despite the commitments outlined in the 2018 peace deal that ended the country's civil war, progress toward meaningful change has been slow.
In response to the report's findings, South Sudan's government issued a warning, threatening to terminate the mandate of the U.N. Human Rights Commission.
"Despite South Sudan having made enormous progress on human rights issues, the government is experiencing a difficult relationship with the commission," Information Minister Michael Makuei said.
He emphasized the need for the commission to share evidence and names of accused individuals and entities for the government's evaluation.
Makuei indicated that the government would consider extending the mandate of the rights group after stripping some of its powers.
"The government accepts that the commission monitors and reports on human rights situations, but its powers of investigation should be relinquished to the government and UNMISS," he stated.
However, human rights activists are skeptical and question the government's sincerity in addressing these issues.
Manyang Gatwech of the Center for Peace and Advocacy noted the lack of government resources allocated for investigations.
Gatwech noted that reports prepared by South Sudan's own rights commission would "disappear simply because the government is not interested in handling the issue of human rights in the country."
