🚨 CVE-2026-16529
A signed integer overflow in the PCP __pmGetPDU() function can be exploited via crafted network packets during PDU processing or SASL negotiation. This permanently blinds the affected daemon, resulting in a total denial of service (DoS) for subsequent packet reads.

🚨 CVE-2026-15816
A flaw was found in dracut. The die() error-handling function writes its message into a shell script under the initramfs emergency-hook directory without properly shell-quoting it. When the message contains data derived from the DHCP ROOT_PATH option, an attacker on the adjacent network who controls a rogue DHCP server can inject a command-substitution sequence that executes as root the next time dracut sources its emergency hook scripts during standard boot-failure handling.

🚨 CVE-2026-79654
A flaw was found in Katello where the Content View History API does not properly enforce authorization when accessing a Content View specified by the user. An authenticated user with permission to view Content Views in one organization may be able to access the lifecycle history of a Content View belonging to another organization by supplying its identifier to the affected API endpoint. This can result in unauthorized disclosure of Content View lifecycle information, including publication and promotion events, associated users, and timestamps.

🚨 CVE-2026-12405
A flaw was found in rubygem-foreman_remote_execution. A command injection vulnerability exists in the Red Hat Satellite API (/api/v2/job_invocations). When a job template has the effective_user property marked as overridable: true, the application fails to properly sanitize the effective_user input provided during the API request. The exploitation does not rely on the content or logic of the Job Template/playbook itself; rather, the injection occurs during the instantiation of the job execution environment by the Satellite server. An attacker with permissions to execute job templates can inject arbitrary shell commands into this parameter, which are executed on the target infrastructure with the privileges of the execution user.

🚨 CVE-2026-12423
A flaw was found in Foreman. The Red Hat Satellite /unattended/provision API endpoint is vulnerable to an authentication bypass due to a semantic logic flaw in host_verifier.rb. The application verifies the database state of a provisioning token rather than its actual presence in the incoming HTTP request. Because a host actively undergoing provisioning has an unexpired token in the database, the server's valid_host_token? method evaluates to true, granting access to the kickstart template even if the requester provides no token at all in the URL.

🚨 CVE-2026-12541
A flaw was found in Foreman. OS command injection vulnerabilities exist in the foreman-rake db:dump and db:import_dump tasks. The application fails to properly sanitize user-supplied input in the destination parameter (during backups) and the file parameter (during imports) before passing them to a Ruby system() call for execution. An attacker with permissions to execute foreman-rake (e.g., via a restricted sudo configuration) can append malicious shell commands to the provided file paths.

🚨 CVE-2026-12544
A flaw was found in Foreman. The foreman-rake initialization logic in /usr/share/foreman/config/settings.rb contains a vulnerable code pattern where configuration data is processed through two distinct executable layers. This creates a multi-stage execution chain that allows for both Server-Side Template Injection (SSTI) and insecure deserialization. This vulnerability can lead to remote code execution, total infrastructure compromise and supply chain risk.

🚨 CVE-2026-96658
A flaw was found in Foreman. An authenticated attacker with low-level permissions can achieve remote code execution (RCE) by bypassing the safemode sandbox within the templating engine. Due to improper handling of delegated methods, an attacker can append unauthorized functions to the allowed execution list, enabling them to run arbitrary commands on the hosting server.

🚨 CVE-2026-96659
A flaw was found in Foreman. This vulnerability allows an authenticated user with low-level Viewer permissions to cause unauthorized information disclosure by submitting requests to template preview endpoints. By exploiting this issue, the user can access sensitive data, such as host root passwords. Furthermore, under insecure system configurations where Safemode protections are disabled, the flaw may allow the user to execute arbitrary commands as the Foreman system account.

🚨 CVE-2026-12542
A flaw was found in Foreman. The foreman-tail utility is vulnerable to OS command injection due to the unsafe use of the eval command. The script takes user-supplied arguments and incorporates them directly into a string that is then executed by eval to expand file paths. Because the input is not sanitized or quoted, a local attacker can inject shell metacharacters (e.g., ;, &, |) to execute arbitrary system commands.

🚨 CVE-2026-12545
A flaw was found in rubygem-hammer_cli. A command injection vulnerability exists in Hammer CLI and the Railties (Ruby on Rails) component distributed with Satellite due to the insecure interpolation of the $EDITOR environment variable into the Ruby system() method. By passing a single interpolated string to system(), the application invokes a system shell (/bin/sh) that interprets shell metacharacters (e.g., ;, |, &).

🚨 CVE-2026-56097
A flaw was found in rubygem-katello. An SQL injection vulnerability exists in the Red Hat Satellite Katello Registry Proxy. The application fails to sanitize input parameters used in database queries within the RegistryProxiesController. The methods check_blob_push_org_label and get_matching_products_from_org take user-supplied labels directly from the request path and interpolate them into raw SQL fragments. This flaw is accessible to a user with only the create_personal_access_tokens permission, even if the user access is restricted, with no Organization or Location assigned.

🚨 CVE-2026-56098
A flaw was found in rubygem-katello. The RegistryProxiesController in Katello contains an authorization bypass vulnerability due to an execution fall-through in the registry_authorize filter. While the application identifies unauthorized requests and triggers an error response via the unauthorized method, it fails to halt the execution of the current code path (missing return statement). This failure in the control flow allows the application to proceed into subsequent business logic and database validation filters. Consequently, the application reveals its internal state through differential responses, allowing an unprivileged attacker to enumerate valid Users, Organizations, and Products across the entire instance.

🚨 CVE-2026-103764
Mooncake transfer engine before 0.3.13 contains an untrusted pointer dereference in ServerSession::readHeader that allows unauthenticated attackers to read and write arbitrary process memory via the TCP transport data port. Attackers can send a crafted SessionHeader with arbitrary addr and size values using READ or WRITE opcodes to disclose KV cache contents, prompts and secrets or corrupt memory toward code execution.

🚨 CVE-2026-103765
Mooncake through 0.3.13.post1 contains a missing authentication vulnerability in the HTTP metadata server /metadata handler that allows unauthenticated attackers to read, overwrite, and delete transfer engine metadata keys. Attackers can poison segment descriptors such as tcp_data_port or re-create rpc_meta entries to redirect KV cache transfers to attacker-controlled listeners, or exhaust server memory.

🚨 CVE-2026-103766
ClipBucket v5 through 5.5.3-#197 contains an sql injection vulnerability that allows authenticated users with ad_manager_access permission to inject SQL via the delete parameter in admin_area/ads_manager.php. Attackers can supply time-based blind payloads concatenated into AdsManager::DeleteAd queries to extract user credentials and emails or modify and delete arbitrary records.

🚨 CVE-2026-86345
A flaw was found in 389-ds-base. The server does not discard plaintext bytes already buffered from a client connection when negotiating StartTLS, allowing an on-path attacker to inject a crafted LDAP message that is processed after the TLS upgrade and whose response is delivered to the client in place of the client's own pending operation's response, due to messageID collision. This can cause a client application to treat a failed authentication (bind) attempt as successful.
