A now-patched high-severity security vulnerability in WhatApp’s image filter feature could have been abused to send a malicious image over the messaging app to read sensitive information from the app’s memory.

Tracked as CVE-2020–1910 (CVSS score: 7.8), the flaw concerns an out-of-bounds read/write and stems from applying specific image filters to a rogue image and sending the altered image to an unwitting recipient, thereby enabling an attacker to access valuable data stored the app’s memory.
