Users of WhatsApp are advised to review their settings and ensure they have the most recent version of the app installed following the identification of two security vulnerabilities by security researchers. These vulnerabilities affect how media files and attachments are managed, as well as WhatsApp for Windows users, potentially making it easier for cybercriminals to conduct social engineering attacks or exploit other vulnerabilities for more severe threats, according to Malwarebytes experts.
The vulnerabilities, known as CVE-2026-23866 and CVE-2026-23863, were uncovered through Meta’s Bug Bounty program. While there is no evidence of these flaws being exploited in real-world attacks or used to infect devices, WhatsApp has released an update to address the issues. The company strongly recommends that users verify their settings and ensure their WhatsApp app is up to date to stay protected.
To update WhatsApp on Android devices, users can access the Google Play Store, search for WhatsApp Messenger, and select “Update.” iPhone users should open the App Store, tap their profile icon, find WhatsApp, and choose “Update.” Once the update is completed, devices will be safeguarded against potential future attacks.
In related news, older Android devices may soon lose access to WhatsApp as the messaging service plans to cease support for devices running versions older than Android 6 starting from September 8, 2026, as reported by WABetaInfo. Affected users may receive a notification stating that WhatsApp will no longer function on their device later this year. However, the impact is expected to be minimal as Android 6 is now outdated and rarely used on modern smartphones.
