Arc Raiders Patched Critical Bug That Saved Discord DMs Locally

Privacy Bug Fixed in Latest Patch#

According to Dexerto, Embark Studios has patched a critical privacy issue in ARC Raiders where players' private Discord direct messages were being saved in plaintext to local game log files on their PCs. The problem was discovered by Timothy Meadows and fixed on March 5, 2026.

The issue affected PC players using the integrated Discord app within Arc Raiders. Private DM conversations between two users were being written directly to local game log files, creating an unintended privacy risk. This wasn't just metadata or usernames - actual message content was being dumped into text files that anyone with access to the PC could potentially read.

For context, Arc Raiders launched its Discord integration to let players coordinate raids and communicate without alt-tabbing out of the game. It's the kind of quality-of-life feature that sounds great on paper, but this incident shows how even well-intentioned integrations can create unexpected vulnerabilities.

Embark Studios clarified that the data never left players' machines: "Rest assured that your private and/or personal data was not sent outside your machine and Embark has (and will not) review or keep such information." While that's reassuring from a data breach perspective, it doesn't eliminate the risk entirely. Anyone sharing a PC, anyone with physical access to your machine, or malware that scans local files could theoretically access those logs.

Root Cause and Response#

The problem stemmed from debugging features in Discord's Social SDK intended for developers. Essentially, tools meant to help developers troubleshoot integration issues were left active in the production build, quietly logging everything that passed through the Discord connection. It's the kind of oversight that happens when debug code doesn't get properly stripped out before release - a mistake that's embarrassingly common in software development, but particularly damaging when it involves private communications.

Discord responded by stating it will provide additional guidance to developers and update the Social SDK with new protections to prevent similar issues in the future. This suggests Discord recognizes that relying on developers to remember to disable debug features isn't sufficient. The updated SDK will likely include safeguards that prevent verbose logging by default or require explicit opt-in for detailed debugging.

While the saved data remained local and required direct access to the device or files to view, the severity of accidentally logging private conversations prompted swift action from both Embark and Discord. The gaming community has become increasingly sensitive to privacy issues, especially after high-profile breaches and controversies involving player data. Embark likely understood that even a local-only issue could seriously damage trust if left unaddressed.

What This Means for Players#

Players can now safely use the Discord integration again following the patch. Those who prefer can also remove the integration entirely through the game's settings. If you're concerned about what might already be in your log files, you can manually delete them - they're typically found in your Arc Raiders installation directory under a logs or debug folder.

The incident highlights the risks that can emerge from third-party SDK implementations, even when developers have no malicious intent. Every external library or service a game integrates represents a potential attack surface or privacy concern. Discord's SDK, Unity's analytics, anti-cheat systems - they all require a degree of trust that the implementation is secure and respects player privacy.

This also raises questions about what other games might have similar issues lurking unnoticed. Arc Raiders only caught this because someone specifically looked for it. How many other titles are using Discord's Social SDK with the same debug features enabled? It's a reminder that privacy audits and security reviews need to be standard practice, not afterthoughts.

Have you been using the Discord integration in Arc Raiders, or does this make you more cautious about in-game social features? It's worth thinking about which integrations you actually need versus which ones just add unnecessary risk to your setup.
