Technical description

Semaphore UI is a web interface for managing DevOps tools. Prior to 2.18.19 and from 2.19.0-alpha3 until 2.19.5-beta5, ProjectMiddleware and GetProjectOrGlobalRoleBySlug allow a project manager to use POST /api/project/{id}/roles to create a custom manager role with permission bitmask 15, overriding the built-in manager permissions and granting CanUpdateProject and CanManageProjectUsers owner capabilities. This issue is fixed in versions 2.18.19 and 2.19.5-beta5.

———RustFS is a distributed object storage system built in Rust. RustFS AddServiceAccount in rustfs/src/admin/handlers/service_account.rs accepts an attacker-controlled target_user after only checking CreateServiceAccountAdminAction, passes it to new_service_account, and prepare_service_account_auth sets is_owner for the resulting root-parent service account. This issue is fixed in version 1.0.0-beta.11.7h CVE-2026-687527.2 HIG

——0A flaw was found in the multicloud-operators-channel component of Red Hat Advanced Cluster Management (RHACM). This vulnerability allows a compromised agent from a managed cluster to gain unauthorized access to sensitive information. Specifically, the agent can read all Secrets and ConfigMaps within any Channel namespace on the hub, potentially exposing credentials for other tenants' Git and Helm repositories. This could lead to significant information disclosure.5h CVE-2026-187026.4 MED

——0An issue in MongoDB Server could allow an authenticated user with limited, database-scoped privileges to modify diagnostic logging settings that affect the entire server rather than just the intended database. This could allow suppression of diagnostic logging server-wide, potentially obscuring unauthorized activity, or degrade operational monitoring by causing excessive log volume.1d CVE-2026-154268.8 HIG

——0The AcyMailing – An Ultimate Newsletter Plugin and Marketing Automation Solution for WordPress plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 10.11.1. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to overwrite the BCC field of the acy_notification_cms notification template, causing subsequent WordPress password-reset emails — including those targeting administrator accounts — to be silently copied to an attacker-controlled address, enabling account takeover via the captured reset link. Successful exploitation requires the site administrator to have enabled the "Send website emails with AcyMailing" option, which routes WordPress core notification emails through AcyMailing's templating system.5h CVE-2026-73218—
