- Whatsapp has resolved bug that had exposed the phone numbers of around 29,000 to 300,000 users online.
- WhatsApp has removed leaked links from http://api.whatsapp.com in the Google search engine.
- The numbers were exposed due to Whatsapp's click to chat feature.
A glitch in WhatsApp had accidentally exposed the phone numbers of some users on Google but now the company has resolved the issue. A day after researcher Athul Jayaram unearthed the bug that leaked many phone numbers due to a click to chat feature on WhatsApp, the company fixed the issue.
As per the researcher, WhatsApp's click to chat feature, which had exposed the numbers of users, allows users to create a link through which users can get in touch with them directly. Jayaram claims that WhatsApp doesn't encrypt the phone number so when you share the link, you also accidentally expose the phone number in plaintext
However, in a statement issued by the company, WhatsApp has said that the feature was created for users to connect better. "Our Click to Chat feature, which lets users create a URL with their phone number so that anyone can easily message them, is used widely by small and microbusinesses around the world to connect with their customers. While we appreciate this researcher's report and value the time that he took to share it with us, it did not qualify for a bounty since it merely contained a search engine index of URLs that WhatsApp users chose to make public. All WhatsApp users, including businesses, can block unwanted messages with the tap of a button," a WhatsApp spokesperson said.

Jayaram, who discovered the bug in WhatsApp, has also confirmed that WhatsApp has removed leaked links from http://api.whatsapp.com in the Google search engine. As per him, 400000 Whatsapp numbers that were exposed due to click to chat features have been removed from the Google search engine. "Web is a safer place today," he tweeted.
