# Publish a vulnerability disclosure policy

For AI agents: the [site map](https://agentwranglers.se/llms.txt) lists everything here, and this page sits under [Errors, logs and vulnerabilities](https://agentwranglers.se/playbook/application-security/errors-logs-and-vulnerabilities.md).

By [Agent Wranglers](https://agentwranglers.se/authors/agent-wranglers.md). Updated 2026-10-27.

- ID: APS-107
- Level: Recommended
- Chapter: [Errors, logs and vulnerabilities](https://agentwranglers.se/playbook/application-security/errors-logs-and-vulnerabilities.md)
- Rule: Publish a vulnerability disclosure policy at a fixed address and link it from `security.txt`. It names what is in scope, how to report, how fast you answer, and that you will not take legal action against good-faith research.
- Check: The policy page answers 200, and the `Policy:` line of `security.txt` names it. A script reads the page and fails unless it holds the words scope, report, safe harbour and a number of days. A test report sent through the channel gets a reply from a person within the promised time.
- How: A policy tells a finder what to expect, so they report to you instead of posting the hole. State the systems in scope and the tests you do not allow, such as floods or reading other people's data. Give one reporting channel, such as a form or a monitored mailbox. Promise to acknowledge each report within the triage time in [Fix each finding within the time its severity allows](https://agentwranglers.se/playbook/application-security/errors-logs-and-vulnerabilities/fix-deadlines.md). Say when you will publish details, such as 90 days after the report or when the fix ships, whichever comes first. Point the `Policy:` field of [security.txt](https://agentwranglers.se/playbook/website/standard-addresses/security-txt.md) at it. A product under the EU Cyber Resilience Act must have such a policy, as [Handle vulnerabilities for the whole support period](https://agentwranglers.se/playbook/compliance/security-laws/cra-support-period.md) says. Open source projects follow [Send private reports to at least two people](https://agentwranglers.se/playbook/open-source/vulnerabilities-and-advisories/security-contacts.md).

## Examples

**Using these examples:** they show one way to follow this rule. Keep the behaviour and the check, not the syntax. Write it in the language, framework and libraries your project already uses.

### Markdown example

```markdown
# Vulnerability disclosure policy

Scope: example.com, api.example.com and our mobile apps.
Not allowed: denial of service, social engineering, reading other customers' data.
Report: https://example.com/security/report
We reply within 2 working days and publish details 90 days after your report, or when the fix ships if sooner.
Safe harbour: we will not take legal action for good-faith research that follows this policy.
```
