In Portainer Community Edition versions 2.33.0 to before 2.33.8, 2.39.2, and 2.41.0 a high severity vulnerability CVE-2026-44848 was detected. This vulnerability allows a standard non-admin user with endpoint access to potentially achieve Remote Code Execution (RCE) on the host system. This occurs because the Docker plugin management endpoints (/plugins/*) lack proper authorization handler registration. As a result, standard users can bypass Resource Control access restrictions and directly call privileged operations, such as installing and enabling plugins, against the underlying Docker daemon. To address this issue, users should upgrade Portainer Community Edition to versions 2.33.8, 2.39.2, or 2.41.0. For more details, visit https://nvd.nist.gov/vuln/detail/CVE-2026-44848.

In MLflow versions prior to 3.11.0 a critical severity vulnerability CVE-2026-4035 was detected. This vulnerability allows an attacker to exfiltrate sensitive server-side environment credentials, such as AWS access keys, to an attacker-controlled endpoint. This occurs because the api_key field in AI Gateway secrets incorrectly resolves environment variable references (e.g., $ENV_VAR) against the MLflow server’s environment during runtime. The resolved secrets are then sent in provider authentication headers to a configured upstream api_base. This can be exploited by unauthenticated users in default deployments or low-privileged users in basic-auth deployments, potentially leading to artifact poisoning and cross-boundary code execution. To address this issue, users should upgrade MLflow to version 3.11.0. For more details, visit https://nvd.nist.gov/vuln/detail/CVE-2026-4035.

In authentik versions prior to 2025.12.6, 2026.2.4, and 2026.5.1 a high severity vulnerability CVE-2026-49443 was detected. This vulnerability allows an attacker to log into any user’s account (Account Takeover). This occurs because an attacker who has the ability to change a source connection and possesses an account in one of the configured sources can exploit improper validation of the source connection to bypass authentication. To address this issue, users should upgrade authentik to versions 2025.12.6, 2026.2.4, or 2026.5.1. For more details, visit https://nvd.nist.gov/vuln/detail/CVE-2026-4944.

In Appsmith versions versions prior to 2.1 a medium severity vulnerability CVE-2026-7299 was detected. This vulnerability allows an authenticated user with Developer privileges to inject a persistent Cross-Site Scripting (XSS) payload, leading to arbitrary code execution in the sessions of other workspace members. This occurs because the SQL query editor’s autocomplete functionality fails to sanitize database object names before rendering them in innerHTML. An attacker can exploit this by creating malicious table or column names, which then trigger the payload when other users interact with the same datasource. To address this issue, users should upgrade Appsmith to version 2.1 and later. For more details, visit https://nvd.nist.gov/vuln/detail/CVE-2026-7299.

In Django versions 6.0 before 6.0.6 and 5.2 before 5.2.15 a low severity vulnerability CVE-2026-6873 was detected. This vulnerability allows a remote attacker to use a signed cookie in a context different from the one where it was originally signed. This occurs because the django.http.HttpRequest.get_signed_cookie function uses a non-injective salt derivation method that simply concatenates the cookie name and the salt argument. An attacker can exploit this by utilizing distinct (name, salt) pairs that produce the exact same string concatenation. To address this issue, users should upgrade Django to versions 6.0.6 or 5.2.15.

In Kibana versions up to and including 8.19.15, prior to 9.3.3, 9.2.8, up to and including 9.4.1 a high severity vulnerability CVE-2026-42398 was detected. This vulnerability allows an authenticated user with connector management privileges to perform a Server-Side Request Forgery (SSRF) attack and bypass operator-configured connection allowlists. This occurs because an attacker can configure a Webhook connector with a specially crafted target, forcing Kibana to issue outbound requests to destinations that were intended to be blocked by egress restriction controls. To address this issue, users should upgrade Kibana to version 9.2.8 or 9.3.2. For more details, visit https://nvd.nist.gov/vuln/detail/CVE-2026-42398.
