WhatsApp’s Image “View Once” Feature Flaw Allowing Unlimited Views

WhatsApp’s “View Once” option is one of the privacy features in the instant messaging space that is intended to provide users with a sense of security.

This feature allows users to send photos or videos that disappear after being viewed once, ensuring sensitive content does not remain. 

However, recent discovery have revealed vulnerabilities in this feature, challenging its effectiveness and raising concerns about user privacy.

The Discovery of a Vulnerability

The “View Once” feature is intended to work as follows:

• A sender shares a photo or video marked as “View Once.”
• The recipient opens the media, views it, and it automatically deletes itself after closing.

Cybersecurity Professional Ramshath has discovered ways to bypass this functionality. 

A “View Once” image was sent to the researcher, who opened it as directed. The image was meant to vanish after viewing. 

However, by navigating to Settings > Storage and Data > Manage Storage within WhatsApp, the image was still accessible under the sender’s chat storage. 

Instead of being deleted immediately after viewing, the media remained stored temporarily in WhatsApp’s file management system.

Meta’s Response

The researcher reported the vulnerability through Meta’s bug bounty program.

“Our investigations show that we have already been aware of this issue internally, and the relevant teams are currently working on a fix to address it. Since we are already in the process of mitigating this issue, we won’t be able to qualify this report for a reward under our bug bounty program”, Meta

Implications for Privacy

The ability to bypass “View Once” undermines user trust in WhatsApp’s privacy features. Key concerns include:

Misuse of Sensitive Content: Media intended for one-time viewing can be saved or shared without the sender’s consent.

False Sense of Security: Users may rely on features like “View Once,” believing their content is safe from unauthorized access or retention.

Risk to the other party: The recipient’s device or third-party tools can compromise the sender’s intent for privacy.

These vulnerabilities highlight a broader issue with digital privacy features: they are only as strong as their implementation and the ecosystem they operate within.

Key Takeaways

Technical Limitations: Even with encryption and deletion mechanisms, digital media can often be intercepted or saved by determined recipients using tools like screen recorders or rooted devices.

Transparency is Crucial: Companies must clearly communicate the limitations of their privacy features to avoid misleading users.

While Meta has taken steps to address some of these issues, such as blocking screenshots for “View Once” media on certain devices, these measures are not foolproof.

The persistence of these vulnerabilities underscores the need for more robust solutions and continuous testing.

For users seeking greater privacy, experts recommend being cautious about sharing sensitive content online, even with features like “View Once.” 

Ultimately, true privacy requires a combination of secure technology and responsible usage practices.

As we navigate an increasingly digital world, features promising privacy must deliver on their assurances or risk eroding user trust in the platforms that provide them.
