🚨 CVE-2026-86186
AVideo API fails to enforce rate limits when clients send a bot User-Agent header, allowing attackers to bypass all eight protected operations including login brute-force protection. Attackers can send requests with a bot User-Agent to disable rate limiting and perform unlimited password guessing attempts against any account from a single IP address.

🚨 CVE-2026-86188
AVideo with YPTSocket plugin enabled contains a cross-site scripting vulnerability allowing unauthenticated attackers to execute arbitrary JavaScript in other users' browsers via the websocket callback mechanism. Attackers can send crafted socket messages with callback names resolving to global functions like avideoConfirmHTML that accept untrusted data and assign it to innerHTML, achieving script execution in the victim's origin without authentication or user interaction.

🚨 CVE-2026-86189
WWBN AVideo contains a path traversal vulnerability in notify.ffmpeg.json.php that allows unauthenticated attackers to write files to arbitrary locations by supplying a caller-chosen path in the avideoRelativePath parameter. Attackers can replay any previously issued ciphertext as a notifyCode token, which is decrypted but never validated, to bypass authentication and write files to the application root and subdirectories.

🚨 CVE-2026-86190
WWBN AVideo contains a broken access control vulnerability in videoViewsInfo endpoints that returns complete user records including password hashes, recovery tokens, and live session identifiers to unauthenticated callers when a hash parameter is provided. Attackers can use the disclosed session identifier to hijack viewer sessions, including administrator accounts, and obtain sensitive personal data for all video viewers.

🚨 CVE-2026-86193
grav-plugin-api before 1.0.20 fails to validate group-inherited super permissions in user-management guards, allowing non-super user managers to modify super-admin accounts. Attackers with api.access and api.users.write can patch password fields on group-super accounts to gain full administrative control.

🚨 CVE-2026-86194
Grav Form Plugin before 9.1.22 fails to verify page authorization when resolving forms by name across pages, allowing anonymous visitors to execute form actions defined on login-restricted or unpublished pages. Attackers can POST to any public page with a restricted form's name to trigger save, upload, email, or call actions without authentication.

🚨 CVE-2026-86195
grav-plugin-api versions before 1.0.20 contain a privilege escalation vulnerability in the InvitationsController where the stripSuperFlags() method only removes nested super flags but fails to strip dot-keyed equivalents like api.super. A non-super user manager with api.access and api.users.write permissions can create an invitation with a dot-keyed super flag in the access payload that bypasses the guard and persists to the new account. Attackers can accept the invitation through the public endpoint without real invitee interaction to create a super-admin account and immediately receive a valid JWT for full site control.

🚨 CVE-2026-86196
Grav API plugin versions before 1.0.20 build password reset links from the untrusted Host header in the forgot-password endpoint, allowing unauthenticated attackers to redirect reset tokens to attacker-controlled domains. Attackers can send password reset requests for any account with a malicious Host header, intercept the reset token from victim emails, and complete account takeover including super-admin accounts.

🚨 CVE-2026-86197
Grav before 2.0.20 contains a cross-site scripting vulnerability in the Twig sandbox policy that allowlists addJs and addCss methods on Grav\Common\Assets without proper output escaping. Page editors can inject arbitrary script by registering malicious assets or injecting attributes, which are rendered unescaped into document head tags and executed for all visitors including administrators.

🚨 CVE-2026-4740
A flaw was found in Open Cluster Management (OCM), the technology underlying Red Hat Advanced Cluster Management (ACM). Improper validation of Kubernetes client certificate renewal allows a managed cluster administrator to forge a client certificate that can be approved by the OCM controller. This enables cross-cluster privilege escalation and may allow an attacker to gain control over other managed clusters, including the hub cluster.

🚨 CVE-2026-16242
A flaw was found in the Konnectivity proxy-server configuration for hosted control planes. The agent-facing listener was started without --cluster-ca-cert (and without token-based agent authentication), so client certificates were not validated. A remote attacker who can reach the Konnectivity cluster endpoint could connect as an unauthenticated agent, join the routing pool, and potentially proxy, inspect, modify, or drop control-plane-to-node traffic.

🚨 CVE-2026-10090
A flaw was found in the Application Subscription controller (multicluster-operators-subscription) of Red Hat Advanced Cluster Management for Kubernetes (ACM). A user with namespace-scoped "edit" privileges in an ACM hub namespace can create a Channel resource pointing to a Helm repository they control and a Subscription resource referencing it. The app-subscription controller fetches and applies the Helm chart contents with its own elevated authority, without verifying whether the subscription creator holds the "open-cluster-management:subscription-admin" role and without restricting applied resources to the subscription namespace. This allows the attacker to include cluster-scoped resources in the Helm chart, such as a ClusterRoleBinding granting the attacker's ServiceAccount the "cluster-admin" ClusterRole. Successful exploitation results in full cluster-admin privilege escalation. This contradicts the ACM documentation which states that non-subscription-admin users should have resources deployed into the subscription namespace only.

🚨 CVE-2026-76139
A flaw was found in acm-operator-bundle. The build process for this component downloads and runs a script from a remote source without verifying its authenticity or integrity. This script gains access to sensitive credentials, such as GitHub access tokens and registry passwords, used in the build environment. A remote attacker could exploit this vulnerability to inject malicious code, leading to unauthorized access to build resources and potential compromise of the resulting operator bundle.

🚨 CVE-2026-78408
The nsenter --join-cgroup option opens the target cgroup.procs file as root and leaves that file descriptor open across later namespace and credential changes and across execve(). Because the kernel checks later cgroup migrations using the credentials from the original open, a program run in an attacker-controlled target can inherit root's ability to move host processes between cgroups. After a privileged operator uses --join-cgroup against that target, an unprivileged user can migrate and terminate unrelated root processes.

🚨 CVE-2026-86145
PCRE2 before 10.48 allows a pcre2_dfa_match out-of-bounds write because reuse of a cached workspace block, in a recursive DFA matching workspace, lacks a size check (even though a newly allocated block, for the same purpose, does have a size check). This outcome requires an attacker-controlled regular expression, or a recursive pattern in conjunction with a small heap limit (this can be set through the API).

🚨 CVE-2026-17107
A flaw was found in the cluster-proxy service-proxy component used in Red Hat Advanced Cluster Management for Kubernetes (RHACM) and multicluster-engine (MCE). The service-proxy appends impersonation group headers to proxied requests without first removing caller-supplied values, and the spoke ServiceAccount holds unrestricted impersonation permissions. An authenticated hub principal can inject an Impersonate-Group header to escalate to cluster-admin on every managed cluster.

🚨 CVE-2026-10059
A flaw was found in the Multicluster Engine for Kubernetes ClusterCurator controller. A tenant administrator with namespace-scoped privileges can exploit this vulnerability by creating a namespaced ClusterCurator. This action inadvertently grants the tenant administrator the ability to mint a token for a ServiceAccount with cluster-wide administrative authority. This leads to a privilege escalation, allowing the tenant administrator to gain full control over the cluster.
