CVE-2026-87900

Laravel-Mediable versions 7.0.0 to 7.0.2 contain an incomplete patch for CVE-2026-49972 — the .pht extension is missing from the forbidden_extensions blocklist in config/mediable.php. Apache on Debian and Ubuntu executes .pht files as PHP, allowing an attacker to upload a malicious file and achieve remote code execution.

IBM Concert versions 1.0.0 through 3.0.0 references or accesses memory after it has been freed (use-after-free). An attacker who can influence program execution or input may exploit this condition to corrupt memory, cause application crashes, or execute arbitrary code.

IBM Concert versions 1.0.0 through 3.0.0 is vulnerable to a buffer overflow caused by improper bounds checking. A local user could overflow the buffer and execute arbitrary code on the system.

IBM Concert versions 1.0.0 through 3.0.0 allows an unauthenticated remote attacker to supply specially crafted input that is incorporated into OS commands, resulting in arbitrary command execution. Successful exploitation allows remote code execution with the privileges of the affected application.

RabbitMQ prior to versions 3.13.15, 4.0.20, 4.1.11, 4.2.6, and 4.3.0 — when no CA bundle is available, ssl_options/1 falls back to [{verify, verify_none}] with no warning. An attacker in a man-in-the-middle position can forge the JWKS response, leading the broker to accept arbitrary JWTs.

RabbitMQ prior to versions 3.13.15, 4.0.20, 4.1.11, 4.2.6, and 4.3.0 — the trust-store plugin installs a verify_fun that overrides {bad_cert, unknown_ca} / {bad_cert, selfsigned_peer} when the presented cert "matches" a whitelisted one. The match key relies solely on issuer name and serial number, which can be easily forged, allowing TLS client authentication bypass.

cPanel contains an execution with unnecessary privileges vulnerability that allows remote authenticated users to execute arbitrary code with root privileges.

OS command injection in Plesk allows remote authenticated users to execute arbitrary code with root privileges.

A flaw in the Ansible Automation Platform automation-controller: when copying a WorkflowJobTemplate, the deep-copy permission sanitizer validates only inventory, unified_job_template, and credentials of each cloned node and fails to check instance_groups (and execution_environment and labels) preserved from the original. A user with organization workflow-admin permission but no role on the referenced instance groups can copy a workflow, become its administrator, and launch jobs pinned to instance groups they are not authorized to use — including the control-plane instance group — bypassing the InstanceGroup use_role boundary and causing attacker-influenced automation to run in the control-plane execution context.

A flaw in AWX: the container group pod_spec_override field uses an incomplete blocklist that only restricts automountServiceAccountToken, allowing injection of initContainers, serviceAccountName overrides, and projected service account token volumes. An AAP platform administrator can exploit this to escalate privileges to OpenShift namespace-level access and exfiltrate namespace secrets.
