Descripción técnica

Wallos is an open-source, self-hostable personal subscription tracker. From version 2.0.0 to before version 5.0.0, any authenticated Wallos user (no admin rights required) can make the server open arbitrary outbound SMTP connections to internal/link-local addresses, by setting the SMTP host of their personal email notifications to an internal IP. The per-user notification settings endpoint (endpoints/notifications/saveemailnotifications.php) performs no SSRF validation, and the notification cron (endpoints/cronjobs/sendnotifications.php) feeds that user-controlled host straight into PHPMailer ($mail->Host = $email['smtpAddress']). When the user's subscription notification fires, the server connects to the chosen host:port. This issue has been patched in version 5.0.0.

CVE-2026-83548—

—

———A Pre-authentication SSRF vulnerability exists in the SMA1000 Appliance Work Place interface due to an unintended alternate access path. A remote unauthenticated attacker could potentially exploit this vulnerability to gain unauthorized access to sensitive functionality and perform unauthorized operations.5h CVE-2026-76851—

—

———A Server-Side Request Forgery (SSRF) vulnerability was identified in GitHub Enterprise Server that allowed remote code execution on the instance. Insufficient network isolation allowed malicious pre-receive hook code to impersonate an internal service and redirect trusted internal requests to a privileged service, leading to elevated code execution. Exploitation required pre-receive hook networking to be enabled and either site administrator privileges or write access to a repository containing a configured pre-receive hook. This vulnerability affected all versions of GitHub Enterprise Server prior to 3.22 and was fixed in versions 3.17.20, 3.18.14, 3.19.11, 3.20.7, and 3.21.5. This vulnerability was reported via the GitHub Bug Bounty program.5h CVE-2026-18730—

—

———A server-side request forgery (SSRF) vulnerability was identified in GitHub Enterprise Server that allowed an unauthenticated attacker to cause the Manage API to send crafted outbound requests to an attacker-controlled host. An unauthenticated endpoint parsed an attacker-supplied cluster configuration and issued gateway-to-agent requests whose HMAC authenticated only a timestamp, not the request path or body. An attacker positioned to intercept the outbound request could capture this token and replay it against privileged management agent endpoints. High-availability deployments were not affected due to a topology restriction. This vulnerability affected all versions of GitHub Enterprise Server prior to 3.22 and was fixed in versions 3.17.19, 3.18.13, 3.19.10, 3.20.6, and 3.21.4. This vulnerability was reported via the GitHub Bug Bounty program.5h CVE-2026-87128.3 ALT

—

———Wyoming before 1.10.2 contains a server-side request forgery vulnerability that allows unauthenticated attackers with network access to force outbound connections to arbitrary targets by supplying a malicious `uri` query parameter to the HTTP API. Attackers can pass arbitrary `tcp://` or `unix://` URIs to affected endpoints including /api/info, /api/speech-to-text, and /api/text-to-speech to override the server-configured backend and redirect connections to attacker-chosen hosts.8h CVE-2026-842075.4 MED

———Heym before 0.0.98 fails to apply SSRF egress guards to WebSocket Send and WebSocket Trigger nodes, allowing authenticated users to connect to internal services. Attackers can craft workflow nodes with arbitrary URLs and headers to reach internal services and read responses from the WebSocket Trigger node.9h CVE-2026-841997.7 ALT

—

———Kyverno before 1.16.2 contains a server-side request forgery (SSRF) vulnerability in the APICall feature. The URL field in a Policy's ServiceCall configuration is not validated, so a user with namespace-level Policy creation permissions can direct Kyverno to make HTTP requests to arbitrary internal resources (e.g., cloud metadata endpoints such as 169.254.169.254 or other tenants' resources). Because Kyverno executes these requests using its cluster-wide high-privilege ServiceAccount (a Confused Deputy problem), the responses—potentially including other tenants' secrets and cloud IAM credentials—are returned in the PolicyReport and can be read by the attacker, breaking multi-tenant isolation.11h
