CVE-2026-126643
A cleartext storage flaw was found in the AAP Gateway Operator. When reconciling an AutomationController, the operator reads the protected resource-server Secret (Secret/<aap-name>-resource-server, key controller_resource_server_secret) and copies its plaintext value into the generated AutomationController custom resource under spec.extra_settings (RESOURCE_SERVER.SECRET_KEY). Although the operator uses no_log to keep the value out of its own logs, serializing it into the custom resource exposes it to any principal able to read the AutomationController CR without permission to read the backing Kubernetes Secret, breaking the expected OpenShift RBAC separation between the two resources. The value may also propagate into Kubernetes API/etcd storage, GitOps and Argo diffs and history, rendered manifests, support bundles, and audit data. The resource-server secret is intended for trusted Gateway-to-Controller service authentication, and its disclosure may allow a user to impersonate a trusted Controller service and reach privileged service-index APIs.

CVE-2026-118975
In Progress® Telerik® Reporting prior to version 20.3.26.1110, improper restriction of XML external entity references in the SVG processing engine allows an authenticated attacker with low privileges who can supply SVG content to a report to read local or UNC files, or trigger server-side network requests, from the report rendering host. External XML entities in SVG content were resolved without applying the configured strict resource resolver and report path validation. Disclosed content is limited by the permissions of the rendering process and by what the rendered report output exposes.
-
CVE-2026-90908
A vulnerability in the GenericAdminAuthenticator component of Azul Payara Server and Azul Payara Micro allows a remote, unauthenticated attacker to bypass JMX/RMI administrative access restrictions by spoofing the client host address. Successful exploitation can grant administrative access to the MBean server and lead to remote code execution. Azul Payara Micro is affected only when its JMX connector is enabled.
-
CVE-2026-110003
A vulnerability in the administration REST interface of Azul Payara allows a remote, unauthenticated attacker to bypass secure-admin remote-access restrictions by supplying an arbitrary value in the X-GlassFish-authToken HTTP header. The header's presence waives the remote-rejection check before the token is validated, and an invalid token falls through to password-based authentication, which succeeds without credentials on default domains configured with an empty administrative password. Successful exploitation grants execution of arbitrary administrative commands, equivalent to complete compromise of the server.
-
CVE-2026-47832
The vulnerability lies in the way application credentials are handled within the BOSH deployment. bosh-openstack-cpi-release: all versions from v55 to v55.0.4 (inclusive)

CVE-2026-114556
MailEnable Save Directory Traversal Arbitrary File Creation Vulnerability. This vulnerability allows remote attackers to create arbitrary files on affected installations of MailEnable. Authentication is not required to exploit this vulnerability. The specific flaw exists within the implementation of the Save method. The issue results from the lack of proper validation of a user-supplied path prior to using it in file operations. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of SYSTEM. Was ZDI-CAN-29161.
-
CVE-2026-68549
ClickMigrate is a database migration tool for ClickHouse with automatic SQL migration management and version tracking. Prior to version 1.0.3, a path traversal vulnerability in the revision command allowed a crafted migration name supplied via the -m argument to escape the intended migrations directory. Under specific conditions, an attacker could cause the tool to create a .sql file in an arbitrary location writable by the user executing the command. This issue is only exploitable if an attacker can influence the migration name passed to the revision command, such as through an insecure automation or CI/CD pipeline that forwards untrusted input. This issue has been patched in version 1.0.3.
-
CVE-2026-126935
Zipline before 4.8.0 contains a race condition vulnerability in src/server/routes/raw/[id].ts that allows remote attackers to bypass file maxViews limits through non-atomic view counting. Attackers holding a file link can send parallel requests that read the same pre-increment count, viewing view-limited or delete-on-max-views files beyond their limit.
-
CVE-2026-68538
fulgur converts untrusted HTML/CSS into PDF, commonly on a server that processes input supplied by many tenants. From version 0.15.0 to before version 0.27.0, resolving the CSS counters(name, sep) function in generated content was bounded neither in the size of a single expansion nor in the aggregate work across an element tree. An attacker able to submit HTML/CSS to a fulgur-based conversion service can trigger CPU and memory exhaustion with a trivially small payload, denying service to the host and any co-tenants. This issue has been patched in version 0.27.0.
-
CVE-2026-68539
fulgur converts untrusted HTML/CSS into PDF, commonly on a server that processes input supplied by many tenants. From version 0.4.4 to before version 0.29.0, the CSS string-set named-string values resolved from a document were accumulated per element with no memory budget, letting a small crafted document amplify into large retained memory (and the CPU to copy it) — results in a denial of service. This issue has been patched in version 0.29.0.
-
CVE-2026-68540
fulgur converts untrusted HTML/CSS into PDF, commonly on a server that processes input supplied by many tenants. From version 0.6.0 to before version 0.33.0, quadratic style-list reprocessing during containing-block resolution for absolutely-positioned pseudo-elements cause denial of service. This issue has been patched in version 0.33.0.
-
CVE-2026-67544
Heym builds and runs agentic systems and business-process automations on self-hosted infrastructure. Prior to version 0.0.71, Heym's workflow engine accepts an arbitrary Python code string in the playwrightCode field of a Playwright node. This string is written to a temporary .py file and executed directly by the backend process via subprocess.Popen([sys.executable, script_path]) with no sandboxing, AST validation, or role gate. Any authenticated user — including a freshly registered account — can achieve full remote code execution (RCE) on the backend host, running as the service process user (observed as root in the default Docker deployment). This issue has been patched in version 0.0.71.
-
CVE-2026-67543
Heym builds and runs agentic systems and business-process automations on self-hosted infrastructure. Prior to version 0.0.70, heym hardens one untrusted-code path but not its sibling. The Python tool executor (python_tool_executor.py) treats user code as untrusted and mandates a Docker sandbox (no network, read-only fs, non-root, no docker socket), failing closed. The skill executor (skill_python_executor.py) runs skill Python via a local backend subprocess with no Docker isolation — only a 512 MB RLIMIT and a 7-key env denylist — so a skill executes inside the backend execution context, with filesystem access, network egress, and non-denylisted environment variables that should not be exposed to untrusted/shared skills. In the shipped Docker config (backend runs as root + /var/run/docker.sock mounted), this escalates to host root. This issue has been patched in version 0.0.70.
-
CVE-2026-67449
Portabase is a database backup and restore tool for PostgreSQL, MySQL, MsSQL, MariaDB, Firebird SQL, SQLite, MongoDB, Redis, Files and Docker Volume. Prior to version 1.21.2, a path traversal in the TUS upload webhook handler (app/api/tus/hooks/route.ts) allowed an unauthenticated attacker to overwrite arbitrary files under the private data directory, including /data/private/keys/master_key.bin (the AES-256-GCM master key). This issue has been patched in version 1.21.2.
