🚨 New advisory was just published!
An independent security researcher working with SSD Secure Disclosure has identified a critical vulnerability in vBulletin that allows an unauthenticated attacker to execute arbitrary code on a remote server. The vulnerability has been assigned CVE-2026-61511. Read our full advisory:

Summary A vulnerability in vBulletin has been identified, the vulnerability allows an unauthenticated user to cause the vBulletin to execute arbitrary code (PHP) on the remote server. Vendor Response The vendor has issued a fix available at: https://forum.vbulletin.com/forum/vbulletin-announcements/...

A vulnerability in Cisco Unified Communications Manager can allow unauthenticated attackers to arbitrarily write files to the server. Under the right conditions, this can be leveraged to achieve remote code ex*****on.

Our latest advisory covers the technical details, exploitation path, and remediation guidance:

Finding a 0-day is rarely a matter of luck. It requires understanding complex systems well enough to spot the assumptions, edge cases, and design gaps that escape routine scrutiny. That's precisely what stood out at TyphoonPWN 2026, where researchers uncovered previously unknown vulnerabilities across a diverse set of targets.

Last month, during TyphoonCon 2026, 34 researchers participated in TyphoonPWN, with 13 of them joining remotely from around the world. Over the course of the competition, we saw successful exploitation across a diverse set of targets, including Windows, Linux, LG webOS, and HP printers.

Every submission underwent live technical verification by the SSD team before being accepted. No theoretical reports. No "works on my machine." Exploit chains had to reliably reproduce against the designated targets under competition conditions before payouts were approved.

By the end of the event, SSD had awarded $300,000 USD onsite.

We've seen researchers take techniques developed for a competition environment and later apply the same methodology to uncover vulnerabilities in enterprise software, embedded devices, operating systems, and products that affect millions of users. The line between "competition research" and "real-world research" is often much thinner than people think.

At SSD, we see the same pattern every day through our disclosure program.
Many of the most impactful vulnerabilities don't fit neatly into existing bug bounty ecosystems. Some vendors don't operate public programs. Others have restrictive scopes, low rewards, or lengthy response cycles. Yet the technical quality of the research remains high.

Our goal is simple: provide researchers with another path.
If you've found a novel exploitation technique, an interesting RCE chain, a sandbox escape, an embedded device vulnerability, or a bug that you believe has meaningful security impact, we'd like to review it. Our team handles technical validation, vendor coordination, and disclosure management, while researchers retain the option to stay anonymous throughout the process.

See how a single race condition led to renderer RCE.

In our new article, we examine a high-severity TOCTOU bug between Blink and V8's WebAssembly compiler that allowed a benign module to pass validation while a malicious one was compiled. Because the Wasm JIT pipeline resides outside the V8 heap sandbox, this resulted in renderer RCE without requiring a V8 sandbox escape.

🚨 New advisory was just published!

A pre-auth remote code ex*****on vulnerability was found in the CWMP implementation of ipTIME routers, allowing unauthenticated attackers to execute arbitrary code remotely. This vulnerability was found by Park Minchan from SSD Labs Korea:

Summary An unauthenticated attacker can remotely execute arbitrary code via the CWMP protocol on the ipTIME router. Vendor Response We have tried to reach out to the vendor through multiple channels (email and via KISA) but have not been able to receive any response. Credit The vulnerabilities have....

Want to know how a “small” WebAssembly issue can become a big security problem?

In our new article, SSD Labs researcher, Aaron Cho, analyzes CVE-2024-12053. An arbitrary WebAssembly type confusion vulnerability leading to an RCE. Read about it here:

Summary CVE -2024 -12053 is an arbitrary WebAssembly type confusion vulnerability stemming from a mix-up between the canonical and relative indices of WebAssembly types. The Chromium team noted that this vulnerability was reported to have been exploited in the wild, combined with a sandbox escape te...
