description: A vulnerability in the expo.io framework allows an attacker to take over accounts and steal credentials on an application/website that configured the "Expo AuthSession Redirect Proxy" for social sign-in. This can be achieved once a victim clicks a malicious link. The link itself may be sent to the victim in various ways (including email, text message, an attacker-controlled website, etc).
problem types: The use of AuthSession modules’s useProxy in Expo below SDK 48 may allow OAuth hijacking, which leads to credentials theft and Account Takeover.
affected:
{
vendor: Expo.io
product: Expo AuthSession module
versions:
version: All versions prior to SDK 48.* (Affected SDK 45.*, 46.* and 47.*), status: affected
}
