The woman met Abaaoud because she was a friend of his cousin, Hasna Ait Boulahcen, who died alongside Abaaoud in the police raid.
The woman said she learned from Abaaoud himself and further conversations with his cousin of his plans to imminently launch new attacks on a creche, police station and shopping mall in the La defence business district of Paris. She says that made her decide to call a special hot line.
"She tells me that it's for Thursday and I say to myself I'm going to stop them," the woman said, referring to the moment when her friend Ait Boulahcen told her the precise attack date.
Hours later, police laid siege to the flat where Abaaoud was holed up with Ait Boulhacen and a third person who took part in the attacks.
The Paris prosecutor's office said it was investigating a potential breach of secrecy laws in response to the interview broadcast on Thursday.
The woman complained of having no social life, no job and no psychological support more than two months after the attacks, and said she still had no new identity papers to match the false name she was now obliged to use.
Speaking of Abaaoud's lack of remorse and determination to kill more people, the woman said: "He's proud of himself. He tells it as if he'd gone shopping and found a pack of cut-price washing powder. He's happy."
She said he also told her of how he and 90 others - Syrians, Iraqis, Germans, French and Britons - entered the country from Syria without any official papers ahead of the attacks.
