CVE-2026-111168 (GCVE-0-2026-111168)

Vulnerability from nvd – Published: 2026-10-15 18:57 – Updated: 2026-10-15 19:40

Title

LibreDesk before 2.9.0-rc.8 Stored XSS via SVG Upload Content-Type Parameter

Summary

LibreDesk before 2.9.0-rc.8 contains a stored cross-site scripting vulnerability that allows authenticated agents to execute script by uploading SVGs with malformed Content-Type parameters. Attackers can upload an SVG typed 'image/svg+xml; x' via /api/v1/media so GET /uploads/{uuid} serves it inline without sandbox, running script in any viewing agent's or administrator's session.

** REJECT ** DO NOT USE THIS CANDIDATE NUMBER. ConsultIDs: none. Reason: Upon further research, the maintainer determined that the behavior described by the CVE record is intended behavior. Per the GitHub Security Advisory: "Libredesk is a single-tenant, self-hosted application. Configuring outbound webhook URLs requires an admin-only permission that is not granted by default - the operator must explicitly assign it. Anyone holding this permission already has full administrative control over the application, and outbound HTTP to operator-chosen URLs is the documented purpose of the webhook feature. This is working as designed." Notes: none.

CVE-2025-68927 (GCVE-0-2025-68927)

Vulnerability from nvd – Published: 2025-12-27 00:04 – Updated: 2025-12-29 16:51

Title

Improper Neutralization of HTML Tags in a Web Page in libredesk

Summary

Libredesk is a self-hosted customer support desk. Prior to version 0.8.6-beta, LibreDesk is vulnerable to stored HTML injection in the contact notes feature. When adding notes via POST /api/v1/contacts/{id}/notes, the backend automatically wraps user input in <p> tags. However, by intercepting the request and removing the <p> tag, an attacker can inject arbitrary HTML elements such as forms and images, which are then stored and rendered without proper sanitization. This can lead to phishing, CSRF-style forced actions, and UI redress attacks. This issue has been patched in version 0.8.6-beta.

Severity

7.3 (High)

CVE-2026-111168 (GCVE-0-2026-111168)

Vulnerability from cvelistv5 – Published: 2026-10-15 18:57 – Updated: 2026-10-15 19:40

Title

LibreDesk before 2.9.0-rc.8 Stored XSS via SVG Upload Content-Type Parameter

Summary

LibreDesk before 2.9.0-rc.8 contains a stored cross-site scripting vulnerability that allows authenticated agents to execute script by uploading SVGs with malformed Content-Type parameters. Attackers can upload an SVG typed 'image/svg+xml; x' via /api/v1/media so GET /uploads/{uuid} serves it inline without sandbox, running script in any viewing agent's or administrator's session.

Vulnerability from cvelistv5 – Published: 2025-12-27 00:04 – Updated: 2025-12-29 16:51

Title

Improper Neutralization of HTML Tags in a Web Page in libredesk

Summary

Libredesk is a self-hosted customer support desk. Prior to version 0.8.6-beta, LibreDesk is vulnerable to stored HTML injection in the contact notes feature. When adding notes via POST /api/v1/contacts/{id}/notes, the backend automatically wraps user input in <p> tags. However, by intercepting the request and removing the <p> tag, an attacker can inject arbitrary HTML elements such as forms and images, which are then stored and rendered without proper sanitization. This can lead to phishing, CSRF-style forced actions, and UI redress attacks. This issue has been patched in version 0.8.6-beta.

Severity

7.3 (High)

When adding notes via POST /api/v1/contacts/{id}/notes, the backend automatically wraps user input in \u003cp\u003e tags. However, by intercepting the request and removing the \u003cp\u003e tag, an attacker can inject arbitrary HTML elements such as forms and images, which are then stored and rendered without proper sanitization. This can lead to phishing, CSRF-style forced actions, and UI redress attacks. This issue has been patched in version 0.8.6-beta."
