In Kubernetes (all versions) a medium severity vulnerability CVE-2020-8554 was detected. This vulnerability allows an attacker to intercept traffic intended for specific IP addresses, resulting in a Man-in-the-Middle (MitM) attack. This occurs because the Kubernetes API server allows users who can create a ClusterIP service to freely set the spec.externalIPs field. Additionally, an attacker with privileged access to patch the status of a LoadBalancer service can set the status.loadBalancer.ingress.ip field to achieve a similar effect. There’s no fix available for this issue at the moment. For more details, visit https://nvd.nist.gov/vuln/detail/CVE-2020-8554.

In Portainer Community Edition versions 2.33.0 to before 2.33.8 and 2.39.1 a medium severity vulnerability CVE-2026-44884 was detected. This vulnerability allows any authenticated user to read the file content of any custom template, potentially exposing sensitive environment-specific values such as connection strings, API tokens, or registry credentials. This occurs due to missing authorization checks in the Custom Template file endpoint (GET /api/custom_templates/{id}/file), enabling users to bypass Resource Control access restrictions by enumerating sequential integer IDs. To address this issue, users should upgrade Portainer Community Edition to versions 2.33.8 or 2.39.1. For more details, visit https://nvd.nist.gov/vuln/detail/CVE-2026-44884.

In authentik versions prior to 2025.12.5 and 2026.2.3 a medium severity vulnerability CVE-2026-41577 was detected. This vulnerability allows an attacker to replay expired SAML assertions or use assertions intended for other service providers, potentially leading to unauthorized access. This occurs because the SAML source response processor (ResponseProcessor.parse()) fails to validate the Conditions element on assertions, improperly ignoring the NotBefore, NotOnOrAfter, and AudienceRestriction restrictions. To address this issue, users should upgrade authentik to versions 2025.12.5 or 2026.2.3. For more details, visit https://nvd.nist.gov/vuln/detail/CVE-2026-41577.

In Budibase versions prior to 3.39.0 a high severity vulnerability CVE-2026-48152 was detected. This vulnerability allows an authenticated attacker with basic permissions to exfiltrate stored REST datasource authentication credentials. This occurs because the single-datasource routes are improperly guarded by generic table permissions rather than specific builder/admin roles. A Basic user can update a REST datasource’s base URL (config.url) while maintaining the original redacted authentication secrets. When a saved query is subsequently executed, the application sends the stored authorization headers to the newly set, attacker-controlled URL, leading to credential disclosure. To address this issue, users should upgrade Budibase to version 3.39.0. For more details, visit https://nvd.nist.gov/vuln/detail/CVE-2026-48152.

In MariaDB Server versions before 11.4.10, 11.5.x through 11.8.x before 11.8.6, and 12.x before 12.2.2 a medium severity vulnerability CVE-2026-35549 was detected. This vulnerability allows an attacker to cause a Denial of Service (DoS) by crashing the server. This occurs because when the caching_sha2_password authentication plugin is enabled and in use, sending a specially crafted large packet triggers a crash due to the unsafe use of the alloca function for memory allocation within sha256_crypt_r. To address this issue, users should upgrade MariaDB Server to versions 11.4.10, 11.8.6, or 12.2.2. For more details, visit https://nvd.nist.gov/vuln/detail/CVE-2026-35549.

In GitLab EE versions 18.8 before 18.10.7, 18.11 before 18.11.4, and 19.0 before 19.0.1 a high severity vulnerability CVE-2026-4868 was detected. This vulnerability allows an authenticated user to cause specific Duo AI workflows to run under another user’s identity. This occurs due to an authorization bypass caused by improper user identity resolution when triggering Duo AI workflow runners. To address this issue, users should upgrade GitLab EE to versions 18.10.7, 18.11.4, or 19.0.1. For more details, visit https://nvd.nist.gov/vuln/detail/CVE-2026-4868.
