CVE-2021-39192ghostghost+2
EPSS score1.02%
Ghost is a Node.js content management system. An error in the implementation of the limits service between versions 4.0.0 and 4.9.4 allows all authenticated users (including contributors) to view admin-level API keys via the integrations API endpoint, leading to a privilege escalation vulnerability. This issue is patched in Ghost version 4.10.0. As a workaround, disable all non-Administrator accounts to prevent API access. It is highly recommended to regenerate all API keys after patching or applying the workaround.CVE-2021-29484ghostghost+2EPSS score7.94%
Ghost is a Node.js CMS. An unused endpoint added during the development of 4.0.0 has left sites vulnerable to untrusted users gaining access to Ghost Admin. Attackers can gain access by getting logged in users to click a link containing malicious code. Users do not need to enter credentials and may not know they've visited a malicious site. Ghost(Pro) has already been patched. We can find no evidence that the issue was exploited on Ghost(Pro) prior to the patch being added. Self-hosters are impacted if running Ghost a version between 4.0.0 and 4.3.2. Immediate action should be taken to secure your site. The issue has been fixed in 4.3.3, all 4.x sites should upgrade as soon as possible. As the endpoint is unused, the patch simply removes it. As a workaround blocking access to /ghost/preview can also mitigate the issue.CVE-2021-32817express_handlebars_projectexpress_handlebars+2EPSS score1.27%
express-hbs is an Express handlebars template engine. express-hbs mixes pure template data with engine configuration options through the Express render API. More specifically, the layout parameter may trigger file disclosure vulnerabilities in downstream applications. This potential vulnerability is somewhat restricted in that only files with existing extentions (i.e. file.extension) can be included, files that lack an extension will have .hbs appended to them. For complete details refer to the referenced GHSL-2021-019 report. Notes in documentation have been added to help users of express-hbs avoid this potential information exposure vulnerability.CVE-2024-43409ghostghost+3EPSS score0.32%
Ghost is a Node.js content management system. Improper authentication on some endpoints used for member actions would allow an attacker to perform member-only actions, and read member information. This security vulnerability is present in Ghost v4.46.0-v5.89.4. v5.89.5 contains a fix for this issue.CVE-2026-105682tryghostghostEPSS score0.24%
Ghost is a Node.js content management system. From 1.18.0 until 6.27.0, an SSRF vulnerability in the webhooks feature allowed staff users to probe internal hosts from the Ghost server. This issue is fixed in version 6.27.0.CVE-2026-105648Npmghost+1EPSS score0.30%
Ghost is a Node.js content management system. From 6.0.9 until 6.65.0, a validation issue allowed some functionality, such as Webmentions, to be abused by an unauthenticated user to make limited HTTP requests to hosts in the Ghost server's internal network on some network configurations. A successful attack would not result in any response data being returned. This issue is fixed in version 6.65.0.CVE-2026-105644Npmghost+1EPSS score0.32%
Ghost is a Node.js content management system. From 4.0.0 until 6.67.0, SVG images included in content imports were stored without sanitization. An attacker who convinced an Administrator to import a crafted file could host scripts on the site's domain, possibly resulting in compromise of staff users' admin sessions. This issue is fixed in version 6.67.0.CVE-2026-105677tryghostghostEPSS score0.52%
Ghost is a Node.js content management system. From 6.10.3 until 6.64.0, a vulnerability in how Ghost loads theme translation files allowed an authenticated Administrator to execute arbitrary code on the server via a crafted theme. This issue is fixed in version 6.64.0.CVE-2026-105681tryghostghostEPSS score0.26%
Ghost is a Node.js content management system. From 5.9.0 until 6.44.1, an input validation issue allowed members to access comments they were not authorized to access. This issue is fixed in version 6.44.1.CVE-2026-105643Npmghost+1EPSS score0.27%
Ghost is a Node.js content management system. From version 6.34.0 until 6.67.0, embed cards in the Ghost editor could bypass protections against stored cross-site scripting. Any staff user, including Contributors, could store scripts in post content that ran when another staff user opened the post in the editor, potentially compromising that user’s admin session. Self-hosted sites should leave the new security.embedPreviewUrl configuration option at its default value. This issue is fixed in version 6.67.0.CVE-2026-105675tryghostghostEPSS score0.39%
Ghost is a Node.js content management system. From 4.39.0 until 6.64.0, staff users with permission to view staff invites were able to discover the secret token of pending invites, including invites for roles with higher privileges than their own. This could allow a staff user to escalate their privileges by accepting a pending invite. This issue is fixed in version 6.64.0.CVE-2026-105678tryghostghostEPSS score0.20%
Ghost is a Node.js content management system. From 0.5.0 until 6.64.0, staff users with the Editor or Super Editor role were able to assign their own role to Author and Contributor users, despite not having permission to assign that role. This issue is fixed in version 6.64.0.CVE-2026-105642Npmghost+1EPSS score0.25%
Ghost is a Node.js content management system. From 6.56.0 until 6.67.0, an image processing library bundled with Ghost contained a vulnerability in its SVG handling. Any staff user, including Contributors, could create a bookmark card for an attacker-controlled website, resulting in arbitrary commands being run on the Ghost server. This issue is fixed in version 6.67.0.CVE-2026-105680Npmghost+1EPSS score0.27%
Ghost is a Node.js content management system. From 5.81.0 until 6.60.0, staff with the Author role could delete posts and pages that they did not author. This issue is fixed in version 6.60.0.CVE-2026-105649Npmghost+1EPSS score0.30%
Ghost is a Node.js content management system. From 4.22.0 until 6.65.0, SVG media thumbnails and SVG images uploaded with a non-SVG file extension were stored without sanitization. This allowed any staff user, including Contributors, to host scripts on the site's domain, possibly resulting in compromise of other staff users' admin sessions. This issue is fixed in version 6.65.0.CVE-2026-105679tryghostghostEPSS score0.24%
Ghost is a Node.js content management system. From 6.22.1 until 6.64.0, Ghost restricted the content type used to serve uploaded files to prevent browsers from executing them. On sites using the default local storage adapter, this restriction was not applied, so files uploaded by any staff user were served with a content type derived from their file extension. This could be used to host scripts on the site's domain, possibly resulting in compromise of other staff users' admin sessions. This issue is fixed in version 6.64.0.CVE-2026-105646Npmghost+1EPSS score0.33%
Ghost is a Node.js content management system. From 4.0.0 until 6.67.0, a crafted content import file could cause excessive CPU usage, making the Ghost server unresponsive. Exploiting this requires Administrator access. This issue is fixed in version 6.67.0.CVE-2026-105652tryghostghostEPSS score0.26%
Ghost is a Node.js content management system. From 0.7.2 until 6.64.0, any staff-level user was able to determine the relative ordering of other staff users' hashed passwords. This does not directly disclose password hashes, and does not provide a practical path to recovering a password. This issue is fixed in version 6.64.0.CVE-2026-105651tryghostghostEPSS score0.30%
Ghost is a Node.js content management system. From 5.94.0 until 6.64.0, when creating a bookmark card, Ghost could store non-image files fetched from an external website as bookmark icons or thumbnails. This allowed any staff user, including Contributors, to host arbitrary HTML on the site's domain, possibly resulting in compromise of other staff users' admin sessions. This issue is fixed in version 6.64.0.CVE-2026-105645Npmghost+1EPSS score0.33%
Ghost is a Node.js content management system. From 5.37.0 until 6.67.0, a crafted request to the external media inliner could cause excessive CPU usage, making the Ghost server unresponsive. Exploiting this requires Administrator access. This issue is fixed in version 6.67.0.
