| CVE-2026-56727 | 1 Zammad | 1 Zammad | 2026-09-26 | N/A |
| Zammad is a web based open source helpdesk/customer support system. Prior to 7.0.2, summary In Zammad's inbound PGP email processing, the return value of the gpg verification call was silently discarded. Regardless of whether gpg reported a valid, invalid, or missing signature, the handler unconditionally wrote sign: { success: true, comment: "Good signature" } to the article's security preferences. Impact Any sender could tamper with the body of a multipart/signed PGP email, or craft a message with an entirely fabricated or mismatched signature, and Zammad would display it to the recipient as cryptographically verified with a "Good signature" label. Users and agents relying on Zammad's signature indicator to confirm message authenticity and integrity would be misled into trusting modified or forged content. The vulnerability affects all inbound PGP-signed emails processed while the PGP integration is enabled. This issue is fixed in version 7.0.2. | ||||

| CVE-2026-56731 | 1 Zammad | 1 Zammad | 2026-09-26 | N/A |
| Zammad is a web based open source helpdesk/customer support system. Prior to 7.0.1, a low-privilege authenticated user may inject arbitrary HTML markup, including JavaScript event handlers, into a ticket title via the standard ticket creation workflow. The title is persisted without sanitization. This issue is fixed in version 7.0.1. | ||||
| CVE-2026-56733 | 1 Zammad | 1 Zammad | 2026-09-26 | N/A |
| Zammad is a web based open source helpdesk/customer support system. Prior to 7.0.2 and 7.1.0, this issue concerns a lack of discursive validation within the authorization cascade. It has been determined that the system-level enforcement of access restrictions during the initialization of new identity objects exhibits a discrepancy: Under specific conditions, the granular restrictions of the access key being used are overridden by the latent authorization authority of the parent account. Consequently, this means that the intended separation of functional areas is nullified, resulting in an uncontrolled expansion of administrative discretion. Due to this potential integrity breach of the entire trust environment, an immediate evaluation of the authorization hierarchies is imperative. Impact An attacker can create new administrator accounts despite token restrictions. This grants full access to all system data (tickets, customers, configuration) and allows the attacker to take complete control of the Zammad instance. Abuse Scenario The vulnerability stems from a lack of synergy between the token-based authorization logic and the target system's functional authorization hierarchy, which allows for iterative escalation of the privileged access context. This issue is fixed in versions 7.0.2 and 7.1.0. | ||||
| CVE-2026-56730 | 1 Zammad | 1 Zammad | 2026-09-26 | N/A |
| Zammad is a web based open source helpdesk/customer support system. Prior to 7.0.2, an authorization bypass vulnerability was found that allows an authenticated agent to read knowledge base answer content they should not be able to access. The vulnerable GraphQL mutation is meant to transform a knowledge base answer suggestion so it can be inserted into the ticket editor, but it only checks if the user has the ticket.agent permission. Checking the authorization to the knowledge base answer itself is missing. This vulnerability is fixed in 7.0.2. | ||||
| CVE-2026-56732 | 1 Zammad | 1 Zammad | 2026-09-26 | N/A |
| Zammad is a web based open source helpdesk/customer support system. Prior to 7.0.2, vulnerability in Zammad's HTML sanitization allows injection of specific HTML elements into ticket bodies. When another user views the crafted ticket, the injected element can trigger a logout request, terminating the viewer's session. This vulnerability is fixed in 7.0.2. | ||||
| CVE-2026-63206 | 1 Zammad | 1 Zammad | 2026-09-26 | N/A |
| Zammad is a web based open source helpdesk/customer support system. Prior to 7.1.2, zammad's HTML sanitizer, which blocks remote images in ticket articles and email views, can be bypassed using a shortened URL format that omits the double slash after the scheme (for example a shortened HTTP URL instead of a shortened HTTP URL). Modern browsers treat both forms as equivalent remote URLs. As a result, an attacker who sends a crafted email or ticket can cause the recipient's browser to silently load an image from an external server, revealing when and by whom the ticket was opened. Zammad's "remote content blocked" warning is not shown because the sanitizer does not recognize the shortened form as remote. This issue is fixed in version 7.1.2. | ||||
| CVE-2026-84458 | 1 Zammad | 1 Zammad | 2026-09-26 | N/A |
| Zammad is a web based open source helpdesk/customer support system. Prior to 7.1.2, when the "Automatic account link on initial logon" setting is enabled, Zammad binds an incoming third-party (SSO) identity to an existing local account by matching the email address the identity provider reports, without verifying that the provider actually confirmed ownership of that email. An attacker who controls any identity at a configured provider, including, by default, any Azure AD tenant via Zammad's multi-tenant Microsoft 365 /common app registration, can set that identity's email to a victim's address, authenticate, and be logged in as the victim. This bypasses the victim's local password entirely and affects any existing account, including agents and administrators. Zammad will honor the xms_edov ID token claim when email verification is required in the Microsoft 365 setting, treating a missing claim as unverified. This issue is fixed in version 7.1.2. | ||||
| CVE-2026-56725 | 1 Zammad | 1 Zammad | 2026-09-26 | N/A |
| Zammad is a web based open source helpdesk/customer support system. Prior to 7.0.2, summary An unauthenticated request to POST /api/v1/import/otrs/import_check blocks a Zammad request worker for roughly two minutes. The import_check and import_status actions are missing the setup_done_response guard that other actions in the same controller carry, so they execute on fully set-up production instances. The action enters a retry loop against a blank OTRS endpoint, sleeping for 30 s + 45 s between attempts. Impact An unauthenticated remote attacker denies service to a production Zammad instance. Each request costs almost nothing and forces ~115 seconds of server-side blocking. A few requests per second saturate the Puma worker pool. The condition persists as long as the traffic continues. No account, valid import configuration, or target knowledge beyond the hostname is needed. CSRF token is trivially obtained from any prior GET response. This issue is fixed in version 7.0.2. | ||||
| CVE-2026-56728 | 1 Zammad | 1 Zammad | 2026-09-26 | N/A |
| Zammad is a web based open source helpdesk/customer support system. Prior to 7.0.2, a broken access control vulnerability exists in Zammad's GraphQL API. An authenticated user can access taskbar item data belonging to another user by crafting a request with the target user's taskbar identifier. The taskbar feature stores transient state for active user sessions, including auto-saved ticket drafts. Under certain conditions, the authorization check for taskbar item access is not enforced, allowing a user to read another user's taskbar item data. This vulnerability is fixed in 7.0.2. | ||||
| CVE-2026-61525 | 1 Zammad | 1 Zammad | 2026-09-26 | N/A |
| Zammad is a web based open source helpdesk/customer support system. In 7.0.2 and 7.1.0, zammad's session management for websocket and long-polling connections is susceptible to a path traversal attack. Session identifiers supplied by the client are insufficiently validated before being used to construct internal file paths. When the file-based session store is active (the default configuration), an authenticated attacker can manipulate the session identifier to reference locations outside the intended storage directory, leading to the deletion of arbitrary files and directories on the server. Exploitation requires only a low-privilege authenticated session and a single crafted request. Instances configured to use the Redis-based session store are not affected. This issue is fixed in versions 7.0.3 and 7.1.1. | ||||
| CVE-2026-65828 | 1 Zammad | 1 Zammad | 2026-09-26 | N/A |
| Zammad is a web based open source helpdesk/customer support system. Prior to 7.1.2, the legacy destroy_form action on AttachmentsController deletes UploadCache Store records based solely on a user-supplied form_id without verifying that the requesting user owns those records. An authenticated attacker who learns another user's pending-upload UUID can silently remove temporary file uploads before the victim submits their ticket or article. This issue is fixed in version 7.1.2. | ||||
| CVE-2026-84462 | 1 Zammad | 1 Zammad | 2026-09-26 | N/A |
| Zammad is a web based open source helpdesk/customer support system. Prior to 7.1.2, a security filter that protects Zammad's AI Agent configuration can be bypassed by entering specially crafted text into one of an AI Agent's fields. An administrator with permission to create or edit AI Agents could exploit this to run arbitrary commands on the server that hosts Zammad, potentially reading, modifying, or destroying all data stored on that server. No interaction from other users is needed; the malicious code runs automatically the next time the affected AI Agent processes a ticket. This issue is fixed in version 7.1.2. | ||||
| CVE-2026-100192 | 1 Yzcheng90 | 1 X-springboot | 2026-09-26 | 6.5 Medium |
| X-SpringBoot through 6.0 exposes appKey and appSecret credentials in the GET /application/manager/select endpoint without authentication or field filtering. Unauthenticated attackers can retrieve these credentials and use them to send arbitrary SMS messages through any tenant's SMS provider, enabling SMS bombing and impersonation attacks. | ||||
| CVE-2026-97060 | 1 Yzcheng90 | 1 X-springboot | 2026-09-26 | 7.2 High |
| X-SpringBoot through 6.0 lacks object-level authorization in user management endpoints, allowing sub-administrators to modify or delete users without ownership verification. Attackers with user-management permissions can reset passwords for any account including the super administrator, rebind roles, or delete users via POST /sys/user/update and POST /sys/user/delete endpoints. | ||||
| CVE-2026-97063 | 1 Yzcheng90 | 1 X-springboot | 2026-09-26 | 9.1 Critical |
| X-SpringBoot through 6.0 returns login verification codes in HTTP responses from unauthenticated endpoints GET /sys/mobile/code and GET /sys/email/code without sending them to account owners. Attackers can request codes using known mobile numbers or email addresses, read them from responses, and authenticate as victims via POST /sys/emailOrMobileLogin/login to hijack accounts. | ||||
| CVE-2026-97064 | 1 Yzcheng90 | 1 X-springboot | 2026-09-26 | 9.1 Critical |
| X-SpringBoot through 6.0 ships with a hardcoded static master login verification code 172839 enabled by default in the database seed. Unauthenticated attackers can authenticate as any user by submitting the public master code to the emailOrMobileLogin endpoint with a known email or mobile number. | ||||
| CVE-2026-63205 | 1 Zammad | 1 Zammad | 2026-09-26 | N/A |
| Zammad is a web based open source helpdesk/customer support system. Prior to 7.1.2, when creating or updating an email signature, Zammad processes inline images referenced in the signature body. If a signature body contains an HTML img tag pointing to any existing attachment, the system copies that attachment into a new signature-owned record, without checking whether the user has permission to access the original attachment. The newly created copy is then downloadable by the same channel-admin user, because attachment access is determined by the copy's owner (the signature), not the original object (e.g., a ticket or knowledge-base article). This allows a user with any of the admin.channel_email, admin.channel_google, admin.channel_microsoft365, or admin.channel_microsoft_graph permissions to read attachments they would otherwise be denied access to, such as ticket attachments belonging to groups they are not a member of. This issue is fixed in version 7.1.2. | ||||
| CVE-2026-100303 | 1 Tduckcloud | 1 Tduck-survey-form | 2026-09-26 | 5.4 Medium |
| TDuck survey form through 6.0 lacks authorization checks on FormThemeController write endpoints for global form themes and categories. Authenticated non-admin users can add, modify, or delete themes and theme categories affecting forms owned by other users. | ||||
| CVE-2026-93682 | 2 Php Group, Redhat | 2 Php, Hummingbird | 2026-09-26 | 5.8 Medium |
| When the HTTP stream wrapper follows a redirect and the response carries a Location header with an empty value, the redirect code reads one byte past the end of the heap buffer holding the location. The value of that out-of-bounds byte decides which redirect target is built, so a malicious server controls whether the client is sent to the host root or to the current directory. | ||||
