TYPO3 12 Support: Frequently Asked Questions

Is the TYPO3 12 still supported?

Yes. The TYPO3 12 is currently supported by TYPO3, and third-party support is available as an alternative — issue management, vulnerability remediation, and compliance help independent of the vendor contract.

When is the TYPO3 12 end of service life (EOSL) date?

TYPO3 lists the end of service life for the TYPO3 12 as Apr 30, 2029.

Can I keep using the TYPO3 12 after its EOSL date?

Yes. EOSL means TYPO3 stops issuing patches and support — the software itself keeps running. Third-party support covers it from there: issue management, security vulnerability remediation, and the compliance documentation auditors ask for, for as long as you choose to run it.

How much does third-party support for the TYPO3 12 cost?

Typically 40-70% below the OEM maintenance renewal price. Exact pricing depends on quantity, service level and location — request a quote and we respond within 24 hours.

CVE-2023-24814HIGH8.8Feb 7, 2023TYPO3 is a free and open source Content Management Framework released under the GNU General Public License. In affected versions the TYPO3 core component `GeneralUtility::getIndpEnv()` uses the unfiltered server environment variable `PATH_INFO`, which allows attackers to inject malicious content. In combination with the TypoScript setting `config.absRefPrefix=auto`, attackers can inject malicious HTML code to pages that have not been rendered and cached, yet. As a result, injected values would b
CVE-2024-55921HIGH7.5Jan 14, 2025TYPO3 is a free and open source Content Management Framework. A vulnerability has been identified in the backend user interface functionality involving deep links. Specifically, this functionality is susceptible to Cross-Site Request Forgery (CSRF). Additionally, state-changing actions in downstream components incorrectly accepted submissions via HTTP GET and did not enforce the appropriate HTTP method. Successful exploitation of this vulnerability requires the victim to have an active session o
CVE-2022-23503HIGH7.5Dec 14, 2022TYPO3 is an open source PHP based web content management system. Versions prior to 8.7.49, 9.5.38, 10.4.33, 11.5.20, and 12.1.1 are vulnerable to Code Injection. Due to the lack of separating user-submitted data from the internal configuration in the Form Designer backend module, it is possible to inject code instructions to be processed and executed via TypoScript as PHP code. The existence of individual TypoScript instructions for a particular form item and a valid backend user account with ac
CVE-2025-47941HIGH7.2May 20, 2025TYPO3 is an open source, PHP based web content management system. In versions on the 12.x branch prior to 12.4.31 LTS and the 13.x branch prior to 13.4.2 LTS, the multifactor authentication (MFA) dialog presented during backend login can be bypassed due to insufficient enforcement of access restrictions on all backend routes. Successful exploitation requires valid backend user credentials, as MFA can only be bypassed after successful authentication. Users should update to TYPO3 version 12.4.31 L
CVE-2025-47940HIGH7.2May 20, 2025TYPO3 is an open source, PHP based web content management system. Starting in version 10.0.0 and prior to versions 10.4.50 ELTS, 11.5.44 ELTS, 12.4.31 LTS, and 13.4.12 LTS, administrator-level backend users without system maintainer privileges can escalate their privileges and gain system maintainer access. Exploiting this vulnerability requires a valid administrator account. Users should update to TYPO3 version 10.4.50 ELTS, 11.5.44 ELTS, 12.4.31 LTS, or 13.4.12 LTS to fix the problem.
CVE-2024-22188HIGH7.2Mar 5, 2024TYPO3 before 13.0.1 allows an authenticated admin user (with system maintainer privileges) to execute arbitrary shell commands (with the privileges of the web server) via a command injection vulnerability in form fields of the Install Tool. The fixed versions are 8.7.57 ELTS, 9.5.46 ELTS, 10.4.43 ELTS, 11.5.35 LTS, 12.4.11 LTS, and 13.0.1.
CVE-2025-59022HIGH7.1Jan 13, 2026Backend users who had access to the recycler module could delete arbitrary data from any database table defined in the TCA - regardless of whether they had permission to that particular table. This allowed attackers to purge and destroy critical site data, effectively rendering the website unavailable. This issue affects TYPO3 CMS versions 10.0.0-10.4.54, 11.0.0-11.5.48, 12.0.0-12.4.40, 13.0.0-13.4.22 and 14.0.0-14.0.1.
CVE-2025-59018HIGH7.1Sep 9, 2025Missing authorization checks in the Workspace Module of TYPO3 CMS versions 9.0.0‑9.5.54, 10.0.0‑10.4.53, 11.0.0‑11.5.47, 12.0.0‑12.4.36, and 13.0.0‑13.4.17 allow backend users to directly invoke the corresponding AJAX backend route to disclose sensitive information without having access.
CVE-2024-25121HIGH7.1Feb 13, 2024TYPO3 is an open source PHP based web content management system released under the GNU GPL. In affected versions of TYPO3 entities of the File Abstraction Layer (FAL) could be persisted directly via `DataHandler`. This allowed attackers to reference files in the fallback storage directly and retrieve their file names and contents. The fallback storage ("zero-storage") is used as a backward compatibility layer for files located outside properly configured file storages and within the public web r
CVE-2007-6381MEDIUM6.5Dec 15, 2007SQL injection vulnerability in the indexed_search system extension in TYPO3 3.x, 4.0 through 4.0.7, and 4.1 through 4.1.3 allows remote authenticated users to execute arbitrary SQL commands via unspecified vectors.
CVE-2025-59015MEDIUM6.3Sep 9, 2025A deterministic three‑character prefix in the Password Generation component of TYPO3 CMS versions 12.0.0–12.4.36 and 13.0.0–13.4.17 reduces entropy, allowing attackers to carry out brute‑force attacks more quickly.
CVE-2022-23501MEDIUM5.9Dec 14, 2022TYPO3 is an open source PHP based web content management system. In versions prior to 8.7.49, 9.5.38, 10.4.33, 11.5.20, and 12.1.1 TYPO3 is vulnerable to Improper Authentication. Restricting frontend login to specific users, organized in different storage folders (partitions), can be bypassed. A potential attacker might use this ambiguity in usernames to get access to a different account - however, credentials must be known to the adversary. This issue is patched in versions 8.7.49 ELTS, 9.5.38
CVE-2022-23504MEDIUM5.7Dec 14, 2022TYPO3 is an open source PHP based web content management system. Versions prior to 9.5.38, 10.4.33, 11.5.20, and 12.1.1 are subject to Sensitive Information Disclosure. Due to the lack of handling user-submitted YAML placeholder expressions in the site configuration backend module, attackers could expose sensitive internal information, such as system configuration or HTTP request messages of other website visitors. A valid backend user account having administrator privileges is needed to exploit
CVE-2025-47939MEDIUM5.4May 20, 2025TYPO3 is an open source, PHP based web content management system. By design, the file management module in TYPO3’s backend user interface has historically allowed the upload of any file type, with the exception of those that are directly executable in a web server context. This lack of restriction means it is possible to upload files that may be considered potentially harmful, such as executable binaries (e.g., `.exe` files), or files with inconsistent file extensions and MIME types (for example

Exploiting this vulnerability requires a valid backend user account with access to file entities. TYPO3 versions 9.5.48 ELTS, 10.4.45 ELTS, 11.5.37 LTS, 12.4.15 LTS, 13.1.1 fix th
CVE-2024-34356MEDIUM5.4May 14, 2024TYPO3 is an enterprise content management system. Starting in version 9.0.0 and prior to versions 9.5.48 ELTS, 10.4.45 ELTS, 11.5.37 LTS, 12.4.15 LTS, and 13.1.1, the form manager backend module is vulnerable to cross-site scripting. Exploiting this vulnerability requires a valid backend user account with access to the form module. TYPO3 versions 9.5.48 ELTS, 10.4.45 ELTS, 11.5.37 LTS, 12.4.15 LTS, and 13.1.1 fix the problem described.
CVE-2022-23502MEDIUM5.4Dec 14, 2022TYPO3 is an open source PHP based web content management system. In versions prior to 10.4.33, 11.5.20, and 12.1.1, When users reset their password using the corresponding password recovery functionality, existing sessions for that particular user account were not revoked. This applied to both frontend user sessions and backend user sessions. This issue is patched in versions 10.4.33, 11.5.20, 12.1.1.
CVE-2025-59021MEDIUM5.3Jan 13, 2026Backend users with access to the redirects module and write permission on the sys_redirect table were able to read, create, and modify any redirect record without restriction to the user’s own file-mounts or web-mounts. This allowed attackers to insert or alter redirects pointing to arbitrary URLs – facilitating phishing or other malicious redirect attacks. This issue affects TYPO3 CMS versions 10.0.0-10.4.54, 11.0.0-11.5.48, 12.0.0-12.4.40, 13.0.0-13.4.22 and 14.0.0-14.0.1.
CVE-2025-59020MEDIUM5.3Jan 13, 2026By exploiting the defVals parameter, attackers could bypass field‑level access checks during record creation in the TYPO3 backend. This gave them the ability to insert arbitrary data into prohibited exclude fields of a database table for which the user already has write permission for a reduced set of fields. This issue affects TYPO3 CMS versions 10.0.0-10.4.54, 11.0.0-11.5.48, 12.0.0-12.4.40, 13.0.0-13.4.22 and 14.0.0-14.0.1.
