Disclosure Agent Skill

Disclosure: Finding -> CVE

Turn a proven, novel vulnerability into a coordinated disclosure and a published CVE. Pairs with the research skill (a finding in findings.md) or an engagement FIND. Read [[responsible-disclosure]] first.

Gate (READ FIRST)

• The finding must be proven + reproducible (minimal PoC, affected versions, impact) and novelty-checked (not an existing CVE). If not, go back to the research skill.
• Confirm you are authorised / in safe-harbor for the target. No authorization -> do not proceed (CFAA / Computer Misuse Act). Research on public software you can lawfully analyze is fine; testing live third-party systems needs permission.

Procedure

• Package the report from the finding: title, affected + fixed/tested versions, CWE class, CVSS vector + score, clear repro steps, minimal PoC, impact, suggested remediation, your contact. Redact any real data.
• Find the contact (in order): /.well-known/security.txt, SECURITY.md, security@<vendor>, vendor PSIRT, a bug-bounty platform if they run one, GitHub private vulnerability reporting for OSS, else CERT/CC.
• Report privately over that channel; PGP-encrypt if a key is published. Professional, specific, non-extortive. Offer to validate the fix.
• Coordinate a timeline - propose ~90 days; track it; escalate to CERT/CC if the vendor goes dark past the deadline.
• Request the CVE: vendor CNA assigns it; for OSS open a GitHub Security Advisory (GitHub issues the CVE); otherwise MITRE CVE request form (CNA of last resort). Supply product, versions, CWE, impact, reference.
• Publish the advisory after fix/deadline: CVE ID, affected/fixed versions, CWE, CVSS, description, PoC, impact, remediation, timeline, credit. Mirror to the researcher's blog/GitHub for the portfolio.

Output

• A ready-to-send disclosure report (draft) and a public advisory (draft) saved under the project: raw/research/<project>/advisory.md (and the contact + timeline tracked in findings.md).
• Update the finding status: candidate -> reported -> CVE-<id> -> published.

Wiki feedback

Reusable disclosure lesson (vendor process quirk, CNA tip) -> update [[responsible-disclosure]]. The vuln technique itself -> the matching wiki/techniques/ page via research-ingest.

Report: report + advisory drafts, contact channel, and the disclosure timeline.
