Over the past few months, the TFSec team has been digging deep into Adobe's ecosystem as part of their Public Bug Bounty Program. Our focus was primarily on the Content Credentials SDK and Adobe Commerce (Magento).
Through systematic fuzzing, code review, and deep vulnerability analysis, we identified a total of 25 vulnerabilities that were recently patched by Adobe.
Here is a breakdown of the research and the assigned CVEs.
Target 1: Content Credentials SDK
Bulletins: APSB26-61 & APSB26-53
The Content Credentials SDK is a critical component for content authenticity. We spent significant time analyzing how it parses and validates inputs.
@bau1u identified 20 vulnerabilities in this SDK, primarily consisting of:
- Uncontrolled Resource Consumption (CWE-400)
- Improper Input Validation (CWE-20)
- Integer Overflows/Underflows (CWE-190/191)
These vulnerabilities could be leveraged by an attacker to trigger Application Denial-of-Service (DoS) conditions. Some of these were rated Critical (CVSS 7.5).
@m411 discovered a more severe logic flaw:
- Path Traversal (CWE-22) - CVE-2026-34657
This vulnerability allowed for an Arbitrary File System Write, an Important finding (CVSS 5.5) that required immediate remediation.
Target 2: Adobe Commerce (Magento)
Bulletin: APSB26-49
Adobe Commerce is a massive target. During our analysis, @bau1u and @e0x1337 collaborated to find a cluster of critical vulnerabilities related to resource management.
Note: While Adobe and NIST officially credited only @bau1u in the public bulletin, this was a joint effort. Massive credit goes to @e0x1337 for their crucial help in this research.
- Uncontrolled Resource Consumption (CWE-400) - CVE-2026-34648, CVE-2026-34649, CVE-2026-34650, CVE-2026-34651
These four Critical (CVSS 7.5) vulnerabilities allowed an unauthenticated attacker to cause an Application Denial-of-Service.

Conclusion
All vulnerabilities have been responsibly disclosed and patched by Adobe. We highly recommend all users of these products update to the latest versions as outlined in the respective security bulletins.
We will be releasing deeper technical write-ups and Proof of Concepts (PoCs) for some of these specific vulnerabilities in the future.
