CVE-2024-51991 1 Octobercms 1 October 2026-06-17 N/A 4.9 MEDIUM
October is a Content Management System (CMS) and web platform. A vulnerability in versions prior to 3.7.5 affects authenticated administrators with sites that have the `media.clean_vectors` configuration enabled. This configuration will sanitize SVG files uploaded using the media manager. This vulnerability allows an authenticated user to bypass this protection by uploading it with a permitted extension (for example, .jpg or .png) and later modifying it to the .svg extension. This vulnerability assumes a trusted user will attack another trusted user and cannot be actively exploited without access to the administration panel and interaction from the other user. This issue has been patched in v3.7.5.
CVE-2024-45962 1 Octobercms 1 October 2026-06-17 N/A 4.7 MEDIUM
October 3.6.30 allows an authenticated admin account to upload a PDF file containing malicious JavaScript into the target system. If the file is accessed through the website, it could lead to a Cross-Site Scripting (XSS) attack or execute arbitrary code via a crafted JavaScript to the target.
CVE-2024-25837 1 Octobercms 1 October 2026-06-17 N/A 5.4 MEDIUM
A stored cross-site scripting (XSS) vulnerability in October CMS Bloghub Plugin v1.3.8 and lower allows attackers to execute arbitrary web scripts or HTML via a crafted payload into the Comments section.
CVE-2024-25637 1 Octobercms 1 October 2026-06-17 N/A 3.1 LOW
October is a self-hosted CMS platform based on the Laravel PHP Framework. The X-October-Request-Handler Header does not sanitize the AJAX handler name and allows unescaped HTML to be reflected back. There is no impact since this vulnerability cannot be exploited through normal browser interactions. This unescaped value is only detectable when using a proxy interception tool. This issue has been patched in version 3.5.15.
CVE-2024-24764 1 Octobercms 1 October 2026-06-17 N/A 3.5 LOW
October is a self-hosted CMS platform based on the Laravel PHP Framework. This issue affects authenticated administrators who may be redirected to an untrusted URL using the PageFinder schema. The resolver for the page finder link schema (`october://`) allowed external links, therefore allowing an open redirect outside the scope of the active host. This vulnerability has been patched in version 3.5.15.
CVE-2023-44383 1 Octobercms 1 October 2026-06-17 N/A 5.4 MEDIUM
October is a Content Management System (CMS) and web platform to assist with development workflow. A user with access to the media manager that stores SVG files could create a stored XSS attack against themselves and any other user with access to the media manager when SVG files are supported. This issue has been patched in version 3.5.2.
CVE-2023-44382 1 Octobercms 1 October 2026-06-17 N/A 9.1 CRITICAL
October is a Content Management System (CMS) and web platform to assist with development workflow. An authenticated backend user with the `editor.cms_pages`, `editor.cms_layouts`, or `editor.cms_partials` permissions who would normally not be permitted to provide PHP code to be executed by the CMS due to `cms.safe_mode` being enabled can write specific Twig code to escape the Twig sandbox and execute arbitrary PHP. This issue has been patched in 3.4.15.
CVE-2023-44381 1 Octobercms 1 October 2026-06-17 N/A 4.9 MEDIUM
October is a Content Management System (CMS) and web platform to assist with development workflow. An authenticated backend user with the `editor.cms_pages`, `editor.cms_layouts`, or `editor.cms_partials` permissions who would normally not be permitted to provide PHP code to be executed by the CMS due to `cms.safe_mode` being enabled can craft a special request to include PHP code in the CMS template. This issue has been patched in version 3.4.15.
CVE-2023-43876 1 Octobercms 1 October 2026-06-17 N/A 5.4 MEDIUM
A Cross-Site Scripting (XSS) vulnerability in installation of October v.3.4.16 allows an attacker to execute arbitrary web scripts via a crafted payload injected into the dbhost field.
CVE-2023-37692 1 Octobercms 1 October 2026-06-17 N/A 5.4 MEDIUM
An arbitrary file upload vulnerability in October CMS v3.4.4 allows attackers to execute arbitrary code via a crafted file.
CVE-2023-25365 1 Octobercms 1 October 2026-06-17 N/A 7.8 HIGH
Cross Site Scripting vulnerability found in October CMS v.3.2.0 allows local attacker to execute arbitrary code via the file type .mp3
CVE-2022-35944 1 Octobercms 1 October 2026-06-17 N/A 6.2 MEDIUM
October is a self-hosted Content Management System (CMS) platform based on the Laravel PHP Framework. This vulnerability only affects installations that rely on the safe mode restriction, commonly used when providing public access to the admin panel. Assuming an attacker has access to the admin panel and permission to open the "Editor" section, they can bypass the Safe Mode (`cms.safe_mode`) restriction to introduce new PHP code in a CMS template using a specially crafted request. The issue has been patched in versions 2.2.34 and 3.0.66.
CVE-2022-24800 1 Octobercms 1 October 2026-06-17 6.8 MEDIUM 8.1 HIGH
October/System is the system module for October CMS, a self-hosted CMS platform based on the Laravel PHP Framework. Prior to versions 1.0.476, 1.1.12, and 2.2.15, when the developer allows the user to specify their own filename in the `fromData` method, an unauthenticated user can perform remote code execution (RCE) by exploiting a race condition in the temporary storage directory. This vulnerability affects plugins that expose the `October\Rain\Database\Attach\File::fromData` as a public interface and does not affect vanilla installations of October CMS since this method is not exposed or used by the system internally or externally. The issue has been patched in Build 476 (v1.0.476), v1.1.12, and v2.2.15. Those who are unable to upgrade may apply with patch to their installation manually as a workaround.
CVE-2022-23655 1 Octobercms 1 October 2026-06-17 2.6 LOW 4.8 MEDIUM
Octobercms is a self-hosted CMS platform based on the Laravel PHP Framework. Affected versions of OctoberCMS did not validate gateway server signatures. As a result non-authoritative gateway servers may be used to exfiltrate user private keys. Users are advised to upgrade their installations to build 474 or v1.1.10. The only known workaround is to manually apply the patch (e3b455ad587282f0fbcb7763c6d9c3d000ca1e6a) which adds server signature validation.
CVE-2022-21705 1 Octobercms 1 October 2026-06-17 8.5 HIGH 7.2 HIGH
Octobercms is a self-hosted CMS platform based on the Laravel PHP Framework. In affected versions user input was not properly sanitized before rendering. An authenticated user with the permissions to create, modify and delete website pages can exploit this vulnerability to bypass `cms.safe_mode` / `cms.enableSafeMode` in order to execute arbitrary code. This issue only affects admin panels that rely on safe mode and restricted permissions. To exploit this vulnerability, an attacker must first have access to the backend area. The issue has been patched in Build 474 (v1.0.474) and v1.1.10. Users unable to upgrade should apply https://github.com/octobercms/library/commit/c393c5ce9ca2c5acc3ed6c9bb0dab5ffd61965fe to your installation manually.

The issue has been patched in v2.1.12 of the october/october package. There are no workarounds for this issue and all users should update.
CVE-2021-3311 1 Octobercms 1 October 2026-06-17 6.8 MEDIUM 9.8 CRITICAL
An issue was discovered in October through build 471. It reactivates an old session ID (which had been invalid after a logout) once a new login occurs. NOTE: this violates the intended Auth/Manager.php authentication behavior but, admittedly, is only relevant if an old session ID is known to an attacker.
CVE-2021-32650 1 Octobercms 1 October 2026-06-17 6.5 MEDIUM 8.8 HIGH
October CMS is a self-hosted content management system (CMS) platform based on the Laravel PHP Framework.
