The Zero Day Disclosure Engineer's Advisory Authoring Course

Write the CVE writeup, the vendor timeline, and the customer advisory the way an offensive research lab actually ships them.

The bug is reproduced, the vendor is patched, and the advisory still has to be written before the embargo lifts.

$199 one-time
Tailored to your situation. Access within 24 hours. 30-day money-back.

Includes a hand-built implementation playbook delivered alongside course access, generated for your specific situation.

Why this course

A disclosure engineer's day is bracketed by two artefacts that look nothing like the exploit work in the middle. On one side, the inbound submission triage note that decides whether a researcher gets paid. On the other side, the public advisory that the vendor, the press, and every downstream customer will read on disclosure day. The middle, the reverse engineering, the PoC harness, the CWE mapping, is the part the engineer trained for. The bracketing artefacts are the part that gets graded by everyone outside the lab, and they are usually drafted in the last two hours before the embargo, against a vendor-comms log that does not flatter the timeline. This is the authoring sequence the role actually needs, broken down to the paragraph.

What you walk away with

  • Draft a CVE writeup that holds up to vendor pushback, press scrutiny, and downstream customer questions.
  • Justify a CVSS v3.1 and v4.0 vector in a paragraph a non-technical reader can follow.
  • Sequence vendor communications so the disclosure timeline reads cleanly even when responses were late.
  • Redact a proof of concept so the technique is documented without handing operational capability to copycats.
  • Author customer mitigation guidance that names compensating controls a defender can actually deploy.

The 12 modules

Module 1. The submission triage note that gets a researcher paid
The inbound submission lands with a PoC, a CVSS guess, and a reproduction note. The triage paragraph the disclosure engineer writes back is what sets the bounty tier, the vendor priority, and the researcher's willingness to disclose with the program again. Module one breaks down the four sentences that paragraph has to contain, with worked examples from memory-corruption and logic-bug submissions, and a short editorial pass on what to remove.
Module 2. Reproducing on the lab harness without contaminating the timeline
The reproduction step is where the disclosure clock starts ticking publicly. This module covers harness setup that produces a clean PoC artefact, captures versioned target metadata, and timestamps reproduction in a way the vendor cannot later dispute. Walks through Windows kernel, Linux user-space, embedded firmware, and browser sandbox harness patterns, and the paragraph that documents each one for the eventual advisory.
Module 3. CWE mapping and root-cause paragraphs
The CWE field on the advisory is read by every downstream scanner vendor and every customer GRC team. Picking the wrong CWE produces an entire downstream chain of misclassified findings. Module three covers the root-cause taxonomy across memory safety, deserialisation, authorisation logic, cryptography, and supply-chain insertion, and the one-paragraph root-cause statement that justifies the CWE selection without leaking exploitation detail.
Module 4. CVSS v3.1 and v4.0 justification paragraphs
A score without a justification paragraph is a score that gets argued down. This module covers writing the AV, AC, PR, UI, S, C, I, A justifications for v3.1 and the new v4.0 supplemental metrics in plain English, so a customer security manager who has never run a vector calculator can defend the score in their own risk register. Worked examples on a high-severity SCADA bug and a low-severity browser cache bug.
Module 5. The redacted proof of concept
The PoC paragraph is the most-read part of the advisory and the most-litigated. This module walks through what to include, what to abstract, what to remove entirely, and how to write the missing steps so a defender can still build detection logic without an attacker getting a ready-to-run exploit. Covers PoCs for use-after-free, type confusion, SQL injection, server-side request forgery, and authentication bypass.
Module 6. Vendor communications and the disclosure timeline
The disclosure timeline section of the advisory is a public artefact about a private negotiation. This module covers the email cadence with vendor PSIRT, what to send in writing versus phone, how to log non-responses, how to handle a vendor that asks for a 30 day extension on day 88, and how to write the resulting timeline so it reads as cooperative even when it was not.
Module 7. Press-safe summary paragraph
The summary paragraph is what reporters copy. If it is wrong, the bug gets a name the engineer did not pick and a severity the engineer did not assign. Module seven covers writing a forty-word summary that survives being quoted in a Reuters wire, a vendor press release, and a security newsletter, without overstating impact or understating prerequisites.
Module 8. Customer mitigation guidance that a defender can deploy
Most advisories end with a patch link and nothing else. Customers running unpatched estates need compensating controls they can put in place this afternoon. This module covers writing detection rules, network segmentation guidance, EDR query language snippets, and configuration changes that buy a defender time before the patch lands in change control.
Module 9. Memory safety case studies
Three worked advisories across a Windows kernel pool overflow, a Linux user-space heap UAF, and a browser renderer type confusion. Each is taken from triage note to public advisory, with the redacted PoC, the CVSS justification paragraph, the press-safe summary, and the customer mitigation guidance shown in full. Comparison of how the same root-cause class is written for three different audiences.
Module 10. Deserialisation and supply-chain case studies
Two worked advisories on Java deserialisation in an enterprise middleware product and a malicious package in a public registry. Covers the additional CWE and CVSS subtleties when the bug is in a transitive dependency, the vendor-comms wrinkle when there are three vendors in the chain, and the customer guidance paragraph for downstream consumers who do not know they are exposed.
Module 11. OT and SCADA case studies
Two worked advisories on a PLC firmware bug and a HMI protocol implementation flaw. Covers the additional language the OT customer base needs in the mitigation paragraph, the longer disclosure timeline expected by ICS-CERT and vendor coordination, and the specific CVSS environmental metric considerations when downtime cost dwarfs data confidentiality.
Module 12. The advisory editorial pass
The last module is the editorial checklist a disclosure engineer runs before pressing publish. Cross-checks between the triage note, the CWE, the CVSS vector, the PoC, the timeline, the summary, and the customer guidance, with the specific contradictions and omissions that tend to slip through, and the templates the implementation playbook provisions on day one.

Before and after

Before

Advisories drafted in the last two hours before embargo, with the CVSS justification, the press-safe summary, and the customer mitigation paragraph all written from scratch under pressure, against a vendor-comms log that does not flatter the timeline.

After

Each paragraph of the advisory has a template, an editorial checklist, and a worked example to lean on, so the engineer's hours go into the bug and the redaction call, not into reinventing the writeup for every submission.

What happens if you do not address this

The next high-severity submission ships with a summary paragraph the press misquotes, a CVSS justification the vendor argues down, and a customer mitigation section that just links to the patch. The bug is real and the program loses a quarter of its credibility on the writeup.

Who it is for

A security researcher working inside a coordinated disclosure program. Comfortable with the bug, less comfortable with the press-safe paragraph and the customer mitigation guidance that have to ship alongside it. Drafts advisories under embargo pressure, against vendor responses that arrive late and partially redacted.

Who this is NOT for. Not for bug bounty hunters who only need to write a Hackerone submission and walk away. Not for vendor-side PSIRT engineers whose advisories are governed by an internal legal template. Not for academic researchers writing for a conference paper.

How it arrives

Text-based course in the Art of Service learning environment, plus downloadable templates and worked examples for every module, plus the hand-built implementation playbook delivered alongside course access.

Time investment. About 8 to 10 hours across the twelve modules, plus the time the engineer would already spend on the next advisory drafting cycle.

Why $199 is the right number

Internal disclosure-team wikis assume the engineer already knows how to write the customer paragraph. Conference talks on coordinated disclosure cover the policy, not the paragraph-by-paragraph authoring. Free CVSS calculators score the bug but do not justify it. This course is the authoring sequence the role's day actually runs on.

FAQ

Is this aligned to a specific program's disclosure policy?
No. The modules are built so the engineer can apply them inside whatever coordinated disclosure program they sit in, and the implementation playbook is tailored to that program.
Does this cover the bug discovery side?
No. The course assumes the bug is already reproduced. It covers the authoring sequence around the bug, from triage note to public advisory.
Is there an option for the wider research team?
The single-seat course is 199 USD. Team licensing for a research lab is available on request after enrolment.

30-day money-back guarantee. If after a week of working through the materials this is not what you needed, reply to the receipt email and a full refund is processed. No questions, no forms.
