Drupal core - Moderately critical - Information disclosure - SA-CORE-2025-008

View online: https://www.drupal.org/sa-core-2025-008 Project: Drupal core [1] Date: 2025-November-12 Security risk: *Moderately critical* 10 ∕ 25 AC:Complex/A:None/CI:Some/II:None/E:Theoretical/TD:Uncommon [2] Vulnerability: Information disclosure Affected versions: >= 8.0.0 < 10.4.9 || >= 10.5.0 < 10.5.6 || >= 11.0.0 < 11.1.9 || >= 11.2.0 < 11.2.8 CVE IDs: CVE-2025-13083 Description: The core system module handles downloads of private and temporary files. Contrib modules can define additional kinds of files (schemes) that may also be handled by the system module. In some cases, files may be served with the HTTP header Cache-Control: public when they should be uncacheable. This can lead to some users getting cached versions of files with information they should not be able to access. For example, files may be cached by Varnish or a CDN. This vulnerability is mitigated by the following: 1) Drupal must be configured to handle non-public files using a custom or contributed module providing an additional file scheme. 2) An attacker must know to request a file that has previously been requested by a more-privileged user, and that file must still be cached. Solution: Install the latest version: * If you are using Drupal 10.4, update to Drupal 10.4.9 [3]. * If you are using Drupal 10.5, update to Drupal 10.5.6 [4]. * If you are using Drupal 11.1, update to Drupal 11.1.9 [5]. * If you are using Drupal 11.2, update to Drupal 11.2.8 [6]. Drupal 11.0.x, Drupal 10.3.x, and below are end-of-life and do not receive security coverage. (Drupal 8 [7] and Drupal 9 [8] have both reached end-of-life.)

Drupal core - Moderately critical - Gadget chain - SA-CORE-2025-006

View online: https://www.drupal.org/sa-core-2025-006 Project: Drupal core [1] Date: 2025-November-12 Security risk: *Moderately critical* 14 ∕ 25 AC:Complex/A:Admin/CI:All/II:All/E:Theoretical/TD:Uncommon [2] Vulnerability: Gadget chain Affected versions: >= 8.0.0 < 10.4.9 || >= 10.5.0 < 10.5.6 || >= 11.0.0 < 11.1.9 || >= 11.2.0 < 11.2.8 CVE IDs: CVE-2025-13081 Description: Drupal core contains a chain of methods that is exploitable when an insecure deserialization vulnerability exists on the site. This so-called "gadget chain" presents no direct threat, but is a vector that can be used to achieve remote code execution if the application deserializes untrusted data due to another vulnerability. It is not directly exploitable. This issue is mitigated by the fact that in order for it to be exploitable, a separate vulnerability must be present to allow an attacker to pass unsafe input to unserialize(). There are no such known exploits in Drupal core. Solution: Install the latest version: * If you are using Drupal 10.4, update to Drupal 10.4.9 [3]. * If you are using Drupal 10.5, update to Drupal 10.5.6 [4]. * If you are using Drupal 11.1, update to Drupal 11.1.9 [5]. * If you are using Drupal 11.2, update to Drupal 11.2.8 [6].

Drupal core - Moderately critical - Denial of Service - SA-CORE-2025-005

View online: https://www.drupal.org/sa-core-2025-005 Project: Drupal core [1] Date: 2025-November-12 Security risk: *Moderately critical* 13 ∕ 25 AC:Basic/A:None/CI:None/II:Some/E:Theoretical/TD:All [2] Vulnerability: Denial of Service Affected versions: >= 8.0.0 < 10.4.9 || >= 10.5.0 < 10.5.6 || >= 11.0.0 < 11.1.9 || >= 11.2.0 < 11.2.8 CVE IDs: CVE-2025-13080 Description: Drupal Core has a rarely used feature, provided by an underlying library, which allows certain attributes of incoming HTTP requests to be overridden. This functionality can be abused in a way that may cause Drupal to cache response data that it should not. This can lead to legitimate requests receiving inappropriate cached responses (cache poisoning). This could be exploited in various ways: * Broken rendering of some pages * Unstyled or malformatted pages * Adverse impacts on client-side functionality Changes are being made in the underlying library which will mitigate this problem, but in the meantime Drupal core has been hardened to protect against this vulnerability. Solution: Install the latest version: * If you are using Drupal 10.4, update to Drupal 10.4.9 [3]. * If you are using Drupal 10.5, update to Drupal 10.5.6 [4]. * If you are using Drupal 11.1, update to Drupal 11.1.9 [5]. * If you are using Drupal 11.2, update to Drupal 11.2.8 [6].

The module doesn’t sufficiently filter certain user-provided text leading to a cross-site scripting (XSS) vulnerability. This vulnerability is mitigated by the fact that an attacker must have a role with the permission “administer node form display”. Solution: Install the latest version: * If you use the Simple multi step form module for Drupal, upgrade to a release from the 2.x branch [3], as the 8.x-1.x branch is now unsupported Reported By: * Ide Braakman (idebr) [4] Fixed By: * Diosbel Mezquía (dmezquia) [5] * Ide Braakman (idebr) [6] * Vitaliy Bogomazyuk (vitaliyb98) [7] Coordinated By: * Greg Knaddison (greggles) [8] of the Drupal Security Team * Ivo Van Geertruyen (mr.baileys) [9] of the Drupal Security Team * Juraj Nemec (poker10) [10] of the Drupal Security Team ------------------------------------------------------------------------------ Contribution record [11] [1] https://www.drupal.org/project/simple_multistep [2] https://www.drupal.org/security-team/risk-levels [3] https://www.drupal.org/project/simple_multistep/releases/2.1.0 [4] https://www.drupal.org/u/idebr [5] https://www.drupal.org/u/dmezquia [6] https://www.drupal.org/u/idebr [7] https://www.drupal.org/u/vitaliyb98 [8] https://www.drupal.org/u/greggles [9] https://www.drupal.org/u/mrbaileys [10] https://www.drupal.org/u/poker10 [11] https://new.drupal.org/contribution-record?source_link=https%3A//www.drupal…

In certain scenarios, the module does not fully protect all login mechanisms as expected. This issue is mitigated by the fact that an attacker must already have valid user credentials (username and password) to take advantage of the weakness.

Normal Drupal core security window rescheduled for November 12, 2025 due to DrupalCon - PSA-2025-11-03
by security-news＠drupal.org 03 Nov '25

03 Nov '25

View online: https://www.drupal.org/psa-2025-11-03 Date: 2025-November-03 Description: The upcoming Drupal core security release window [1] has been rescheduled from November 19, 2025 to November 12, 2025. As normal, the window will occur between 1600 UTC and 2200 UTC. .... Schedule change for back-to-back DrupalCons This schedule change is due to DrupalCons Vienna [2] and Nara [3] overlapping the October and November core security windows. We do not schedule core security windows during DrupalCons so that site owners and agencies can attend these conferences without having to worry about their sites or clients. December is also not typically used for core security releases due to the quick sequencing of the Drupal core minor releases and the end-of-year holidays. This would mean a period of four months where we could not provide any regularly scheduled security update. .... No special release procedures The schedule change is not due to any highly critical issue that would require special release procedures. As a reminder, a Drupal core security window does not necessarily mean a Drupal security release will occur, only that one is possible. Coordinated By: * catch (catch) [4] of the Drupal Security Team * Damien McKenna (damienmckenna) [5] of the Drupal Security Team * Neil Drumm (drumm) [6] of the Drupal Security Team * Greg Knaddison (greggles) [7] of the Drupal Security Team * Lee Rowlands (larowlan) [8] of the Drupal Security Team * Drew Webber (mcdruid) [9] of the Drupal Security Team * Juraj Nemec (poker10) [10] of the Drupal Security Team * Jess (xjm) [11] of the Drupal Security Team * Cathy Theys (yesct) [12] of the Drupal Security Team ------------------------------------------------------------------------------ Contribution record [13] [1] https://www.drupal.org/drupal-security-team/security-release-numbers-and-re… [2] https://events.drupal.org/vienna2025 [3] https://events.drupal.org/nara2025 [4] https://www.drupal.org/u/catch [5] https://www.drupal.org/u/damienmckenna [6] https://www.drupal.org/u/drumm [7] https://www.drupal.org/u/greggles [8] https://www.drupal.org/u/larowlan [9] https://www.drupal.org/u/mcdruid [10] https://www.drupal.org/u/poker10 [11] https://www.drupal.org/u/xjm [12] https://www.drupal.org/u/yesct [13] https://new.drupal.org/contribution-record?source_link=https%3A//www.drupal…
