⚠️ We urge security researchers not to publish vulnerabilities in issue trackers or discuss them publicly (e.g. on Slack or Twitter).
The TYPO3 Security Team coordinates the process with the TYPO3 core developers, extension maintainers and other affected parties. Once a security fix is available, we prepare a new release and publish the fixed version. At the same time, we communicate the vulnerability and the fix to the public by using various communication channels such as:
- TYPO3 Security Advisories
- TYPO3 Security Team on Twitter
- #announce channel on Slack
- TYPO3 Announce Mailing List
The TYPO3 Security Team takes care of requesting CVE IDs (Common Vulnerabilities and Exposures identifiers).
We aim to publish TYPO3 maintenance releases on Tuesdays as a general rule. However, exceptions apply (e.g. public holidays). Release dates of maintenance releases are scheduled in advance. These releases can contain security fixes.
