Multiple Cisco Products Snort 3 Software Hardening Release: October 2026

As part of Cisco's ongoing commitment to proactive security and product quality, the Cisco owned Open Source Snort 3 Software engineering team has conducted a comprehensive internal security review. This review resulted in software hardening releases that address multiple internally discovered vulnerabilities. The vulnerabilities tracked by CVE-2026-20043 are related to issues concerning out-of-bounds writes that are grouped under the Common Weakness Enumeration (CWE) Base CWE-787.

The mobile application was found to contain stored credentials for the network it was developed on. If an attacker retrieved this, and found the physical location of the Wi-Fi network, they could gain unauthorized access to the Wi-Fi network of the vendor. Additionally, if an attacker were located in close physical proximity to the device when it was first set up, they may be able to force the device to auto-connect to an attacker-controlled access point by setting the SSID and password to the same as which was found in the firmware file.

Keycloak-services: keycloak-services: saml redirect binding signature bypass via percent-encoded parameter names

A flaw was found in the SAML HTTP-Redirect binding implementation of Keycloak. The issue occurs because the server processes percent-encoded parameter names (like %53AMLResponse) while the signature verification logic only checks literal parameter names. An attacker can use this discrepancy to provide a crafted, unsigned SAML message that the server processes instead of a legitimately signed one, leading to full account takeover of federated users.

Samba: smbd allows client access to unix domain sockets on the file system as root

A path traversal vulnerability was identified in Samba when processing client pipe names connecting to Unix domain sockets within a private directory. Samba typically uses this mechanism to connect SMB clients to remote procedure call (RPC) services like SAMR LSA or SPOOLSS, which Samba initiates on demand. However, due to inadequate sanitization of incoming client pipe names, allowing a client to send a pipe name containing Unix directory traversal characters (../). This could result in SMB clients connecting as root to Unix domain sockets outside the private directory. If an attacker or client managed to send a pipe name resolving to an external service using an existing Unix domain socket, it could potentially lead to unauthorized access to the service and consequential adverse events, including compromise or service crashes.

Multiple Vulnerabilities in IBM API Connect

IBM API Connect 12.1.0.0 through 12.1.1.2 could allow a remote attacker to obtain sensitive information and modify API configurations due to improper authentication. Identity information supplied in requests is not sufficiently verified, which could allow a caller to impersonate another user.

Multiple Vulnerabilities in IBM API Connect

IBM API Connect 10.0.8.0 through 10.0.8.12 and 12.1.0.0 through 12.1.1.2 could allow a remote authenticated attacker to access and modify other tenants' portal data due to improper neutralization of argument delimiters.

Multiple Vulnerabilities in IBM API Connect

IBM API Connect 10.0.8.0 through 10.0.8.12 and 12.1.0.0 through 12.1.1.2 could allow a remote authenticated attacker to obtain sensitive information due to SQL injection.

Multiple Vulnerabilities in IBM API Connect

IBM API Connect 12.1.0.0 through 12.1.1.2 could allow a remote attacker to gain full administrative control due to the use of hard-coded credentials.

Multiple Vulnerabilities in IBM API Connect

IBM API Connect 12.1.0.0 through 12.1.1.2 could allow a remote attacker to obtain sensitive information due to server-side request forgery. A service that can be reached without authentication could be made to send requests to unintended destinations.

Multiple Vulnerabilities in IBM API Connect

IBM API Connect 12.1.0.0 through 12.1.1.2 could allow a remote attacker to obtain sensitive information due to improper validation of endpoint URLs.

node-opcua: Namespace-Level RBAC Fail-Open - Anonymous Write/Call Bypass via Unbound `DefaultRolePermissions

node-opcua is an OPC UA implementation for TypeScript and Node.js. From 2.42.0 until 2.180.0, namespace-level access control configured through setDefaultRolePermissions is not honored by the runtime enforcement path for nodes without explicit per-node RolePermissions. SessionContext.getApplicableRolePermissions reads a missing or null DefaultRolePermissions metadata value instead of the configured namespace field, and the null result is treated permissively. An anonymous network client can consequently write variables with CurrentWrite access or call bound methods when an operator configured a restrictive namespace default and relied on inheritance. Servers with no declared policy, nodes with explicit per-node permissions, and correctly bound programmatic namespace metadata are outside the authorization-bypass case. This issue is fixed in version 2.180.0.

fastapi-code-generator: Import-time RCE via route path -> unescaped @app.get('...') decorator

fastapi-code-generator creates FastAPI applications from OpenAPI files. Prior to 0.8.1, the generator inserts an OpenAPI path into a generated @app.get(...) route decorator as a single-quoted generated route string without escaping embedded quotes. An attacker-controlled or attacker-influenced OpenAPI path can close the string and inject a valid Python expression into the decorator argument. Syntax-breaking input only causes generation to fail, but syntactically valid generated code executes with the application's or CI process's privileges when the generated module is imported and the decorator is evaluated. This OpenAPI path sink is distinct from the project's separate operation-summary docstring and additional-response-key sinks. This issue is fixed in version 0.8.1.

Elo: Sandbox escape to arbitrary Node.js / browser code execution via unfiltered `.constructor` member access in Elo JavaScript emitter

Elo is a purely functional expression language for no-code tools. Prior to 1.0.1, plain Elo strings supplied to defaultFormats.elo.parse(), bin/elo, or elo-lang.org/try can use .constructor.constructor to reach JavaScript Function because the member_access handler in src/transform.ts does not reject meta-properties, src/compilers/javascript.ts emits the surviving property directly, and src/parser.ts accepts constructor as an ordinary identifier. The resulting generated JavaScript executes attacker-selected code in the host runtime. This permits browser script execution and session compromise on the auto-running playground and arbitrary Node.js code execution on library, CI, or DevOps hosts. This plain-string path is distinct from the programmatic AST-object injection issue. This issue is fixed in version 1.0.1.
