Drupal 9.1 Support: Frequently Asked Questions

Is the Drupal 9.1 still supported?

Drupal ended support for the Drupal 9.1 on Dec 8, 2021 — no more patches or fixes from the vendor. Third-party support keeps it covered: our engineers manage issues, remediate vulnerabilities, and help you maintain compliance for as long as you run it.

When is the Drupal 9.1 end of service life (EOSL) date?

Drupal lists the end of service life for the Drupal 9.1 as Dec 8, 2021.

Can I keep using the Drupal 9.1 after its EOSL date?

Yes. EOSL means Drupal 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 Drupal 9.1 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-2023-5256HIGH7.5Sep 28, 2023In certain scenarios, Drupal's JSON:API module will output error backtraces. With some configurations, this may cause sensitive information to be cached and made available to anonymous users, leading to privilege escalation. This vulnerability only affects sites with the JSON:API module enabled, and can be mitigated by uninstalling JSON:API. The core REST and contributed GraphQL modules are not affected.
CVE-2022-25275HIGH7.5Apr 26, 2023In some situations, the Image module does not correctly check access to image files not stored in the standard public files directory when generating derivative images using the image styles system. Access to a non-public file is checked only if it is stored in the "private" file system. However, some contributed modules provide additional file systems, or schemes, which may lead to this vulnerability. This vulnerability is mitigated by the fact that it only applies when the site sets (Drupal 9)
CVE-2022-25273HIGH7.5Apr 26, 2023Drupal core's form API has a vulnerability where certain contributed or custom modules' forms may be vulnerable to improper input validation. This could allow an attacker to inject disallowed values or overwrite data. Affected forms are uncommon, but in certain cases an attacker could alter critical or sensitive data.
CVE-2022-39261HIGH7.5Sep 28, 2022Twig is a template language for PHP. Versions 1.x prior to 1.44.7, 2.x prior to 2.15.3, and 3.x prior to 3.4.3 encounter an issue when the filesystem loader loads templates for which the name is a user input. It is possible to use the `source` or `include` statement to read arbitrary files from outside the templates' directory when using a namespace like `@somewhere/../some.file`. In such a case, validation is bypassed. Versions 1.44.7, 2.15.3, and 3.4.3 contain a fix for validation of such temp
CVE-2022-24775HIGH7.5Mar 21, 2022guzzlehttp/psr7 is a PSR-7 HTTP message library. Versions prior to 1.8.4 and 2.1.1 are vulnerable to improper header parsing.

CVE-2020-13677HIGH7.5Feb 11, 2022Under some circumstances, the Drupal core JSON:API module does not properly restrict access to certain content, which may result in unintended access bypass. Sites that do not have the JSON:API module enabled are not affected.
CVE-2020-36193HIGH7.5Jan 18, 2021Tar.php in Archive_Tar through 1.4.11 allows write operations with Directory Traversal due to inadequate checking of symbolic links, a related issue to CVE-2020-28948.
CVE-2012-2306HIGH7.5Jul 25, 2012SQL injection vulnerability in the Addressbook module for Drupal 6.x-4.2 and earlier allows remote attackers to execute arbitrary SQL commands via unspecified vectors.
CVE-2022-25277HIGH7.2Apr 26, 2023Drupal core sanitizes filenames with dangerous extensions upon upload (reference: SA-CORE-2020-012) and strips leading and trailing dots from filenames to prevent uploading server configuration files (reference: SA-CORE-2019-010). However, the protections for these two vulnerabilities previously did not work correctly together. As a result, if the site were configured to allow the upload of files with an htaccess extension, these files' filenames would not be properly sanitized. This could allow
CVE-2009-4066MEDIUM6.8Nov 24, 2009Multiple cross-site request forgery (CSRF) vulnerabilities in the "My Account" feature in PHPList Integration module 5 before 5.x-1.2 and 6 before 6.x-1.1 for Drupal allow remote attackers to hijack the authentication of arbitrary users via vectors related to (1) subscribing or (2) unsubscribing to mailing lists.
