Before you report a vulnerability, first take the following steps:

• Ensure you are using the latest version of ImageMagick 7 or 6
• Attempt to mitigate the vulnerability using a properly curated security policy
  • Verify your policy using the validation tool
  • Confirm that the security policy mitigation steps did not resolve the issue

If you have completed the above steps and confirmed that the security policy does not address the vulnerability, report the vulnerability as a security advisory. Please include the following information:

• Each user may have no more than three advisories in triage at any one time.
• A description of the vulnerability, including the version of ImageMagick affected.
• Steps to reproduce the vulnerability:
  • Operating system and version (e.g., Ubuntu 20.04, Windows 11, macOS 13.2)
  • Compiler information and build configuration (if building from source)
  • Minimal code sample or command line that demonstrates the vulnerability (if applicable)
  • An input file that can be used to demonstrate the vulnerability (if applicable)
• Any relevant logs or error messages.

Once a vulnerability is reported we will take the following steps:

CVE requests: Reporters should not request or assign a CVE. After validating a report, ImageMagick maintainers will determine whether a CVE is appropriate. If warranted, maintainers will request the CVE through GitHub's Security Advisories. Please do not request a CVE from another CVE Numbering Authority (CNA).

Timelines: The timelines in the incident response plan are targets, not guarantees. Actual remediation dates may vary depending on the complexity of the vulnerability and maintainer availability.
