Tommaso Bona

IT & Security Consultant | AI Security Researcher | ADHD & Autism Advocate

Welcome

As a passionate cybersecurity professional and researcher, I currently serve as an IT & Security Consultant at Tralerighe Service and an Independent AI Security Researcher, specializing in LLMs and AI Model vulnerability discovery. My career is built on a foundation of technical leadership and innovation; as the former Co-Founder and CTO of Voyxa, I led a cross-functional team of 20+ PhD students, consultants and engineers to develop our AI-driven vocal Helpdesk solution. Under my technical steering, Voyxa was recognized as a finalist at Digithon (Italy's largest pitch event) and, among other things, i also served as the technical spokesperson, bringing Voyxa from 0 to a 500k$ evaluation, in only 10 months.

My transition from a SOC Analyst and Cybersecurity Specialist, to a CTO, and now a specialized Consultant, has allowed me to blend deep technical expertise with strategic business development. I also worked as a Business Development Advisor and Marketing Strategist for StationX, where I proposed and helped guide the creation of their new white papers platform, all of which started, with me working remotely for StationX as a "simple" Cybersecurity Writer, for a bit more than a year. Beyond the corporate world, I am a volunteer OSINT Analyst for the Guardian Group's PURSUIT® Team, helping fight child exploitation, together with law enforcement, as well as i've had the privilege of contributing to the Python Software Foundation in multiple ways, and i'm a proud advocate for ADHD and Autism awareness, considering neurodiversity as a vital asset for innovation, in the current cybersecurity landscape.

🛡️ Core Security Contributions

Title Description CVE ID Links
NoSQL injection in Openwhyd controller(): request.body leads to Private Information Disclosure Discovered and responsibly disclosed a Medium severity NoSQL Injection in Openwhyd, leading to Info Disclosure CVE-2026-123617 CVE.org record
GitHub Advisory
Unauthenticated Server-Side Template Injection leading to RCE in LMFDB Discovered and responsibly disclosed a Critical (CVSS4: 10.0) unauthenticated SSTI (CWE-94, CWE-1336) in the L-functions and Modular Forms Database (LMFDB). The /knowledge/render/<ID> endpoint spliced request data, including every query-string key and value, directly into a Jinja template rendered in an unsandboxed environment. A single unauthenticated GET request was enough to achieve OS-level Remote Code Execution, confirmed against the live lmfdb.org production instance with a non-destructive id call. Patched in commit 01829bd. CVE-2026-123198 CVE.org record
GitHub Advisory
Disabled TLS Certificate Verification in OpenAlgo Found by my pyspector-monitor pipeline at SatoriCI. OpenAlgo's SMTP code (versions >= 1.0.0.29, < 2.0.3.1) disabled both hostname and certificate verification (CWE-295), allowing Man-in-the-Middle attacks to capture SMTP credentials and intercept password reset links (account takeover primitive). Medium severity (CVSS4: 6.0). Fixed in v2.0.3.1. CVE-2026-120250 Read the full writeup
CVE.org record
GitHub Advisory
Argument Injection in Red Hat's Ansible-core leading to RCE Found and responsibly disclosed a High severity (CVSS: 7.8) Argument Injection in Red Hat's Ansible-core, leading to Remote Code Execution. CVE-2026-11332 Read the full writeup
NIST NVD
Red Hat Advisory
0-click RCE in psf/black's GitHub Action Discovered and responsibly disclosed a High severity (CVSS4: 8.7) RCE in the official psf/black GitHub Action (2.2B downloads). A permissive regex in action/main.py allowed direct URL references to bypass version validation, enabling arbitrary code execution on CI runners via a malicious pyproject.toml, triggered by the creation of a new pull request with no maintainer interaction required. Patched in v26.3.0. CVE-2026-31900 Read the full writeup
NIST NVD
GitHub Advisory
Remote Code Execution (RCE) in AI Framework Identified and responsibly disclosed a critical RCE vulnerability in a widely used AI library, by leveraging my own SAST framework, PySpector. N/A Research & Proof of Concept
Public Acknowledgement from the U.S. Department of Commerce Discovered and reported a Critical, High-Impact Error-based SQLi, leading to a full database takeover on a US Department of Commerce subdomain. N/A Official acknowledgement
Requests (Python Software Foundation) Reported what was initially thought to be a minor security flaw in the Requests library, which was ultimately classified as a bug and fixed upstream. N/A PR #7308
CPython (Python Programming Language) Contributed to the CPython core test suite by addressing a Path Traversal vulnerability (minor impact, since it only affected the dev test suite). N/A PR #138158
Lead Dev and Maintainer of PySpector State-of-the-art hybrid Rust/Python graph-based SAST framework, made for CI/CD and large Python codebases. Engineered for high-speed, high-accuracy vulnerability scanning, performing 2.1x faster than Bandit and 3.7x faster than Semgrep. N/A GitHub: PySpector
