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-2026-86066——
———Horilla is an HR and CRM software. Prior to 2.0.0, approve_validate_attendance_request at /attendance/approve-validate-attendance-request/ changes attendance_validated, is_validate_request_approved, approved_by, and related pending-request state through an HTTP GET before calling attendance.save(), so Django does not require CSRF validation for the action. An unauthenticated attacker can cause a logged-in manager with attendance.change_attendance to make a top-level request that carries the manager's SameSite=Lax session cookie, silently approving attendance with the victim's privileges and attributing the approval to the victim in the audit trail. This issue is fixed in version 2.0.0.3hCVE-2026-84463——
———Zammad is a web based open source helpdesk/customer support system. Prior to 7.1.2, a user with Knowledge Base editing rights for a category can embed a video widget in a published answer with a specially crafted value. When the answer is rendered, that value is inserted into the page's HTML without being escaped for its attribute context, allowing it to break out and inject additional HTML into the page. When another user who has permission to switch between user sessions views the affected answer, the injected HTML causes their browser to silently send a request to Zammad's session-switching endpoint using their own active credentials. This results in switching their session to an account chosen by the person who wrote the Knowledge Base answer. No action is required from the viewer beyond opening the published answer. This issue is fixed in version 7.1.2.7hCVE-2026-63206——
———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 7.1.2.6hCVE-2026-84462——
———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 7.1.2.7hCVE-2026-944458.8 ALT—
——0A malicious txtar could escape the intended execution context and force arbitrary writes to the playground host's trusted filesystem.
Disjointly, one of the three possible paths to invoke go vet on the playground host did not correctly restrict the execution environment. This permitted a Go process to make a read for an environment configuration file rooted in the playground host's $HOME.
Together, a well-crafted go env file and the go vet invocation could lead to remote code execution in the playground host itself.
This does not affect users of go.dev/play directly; however, it may affect independent deployments of golang.org/x/playground.8hCVE-2026-67234——
——0RabbitMQ is a messaging and streaming broker. From 4.2.0 until 4.2.8 and 4.3.2, get_auth_mechanism/1 used term_to_binary/1 on the strict_auth_mechanism or preferred_auth_mechanism atom when clearing the corresponding cookie, producing a non-ASCII cookie name that violates RFC 6265 and can prevent the browser from deleting the preference. The issue is not directly exploitable for code execution or data exfiltration; its security relevance is limited to stale authentication-mechanism preferences persisting across logout and login cycles. This issue is fixed in versions 4.2.8 and 4.3.2.6h
