| As part of Cisco's ongoing commitment to proactive security and product quality, the Cisco IOS XR Software engineering team has conducted a comprehensive internal security review. This review resulted in a software hardening releases that address multiple internally discovered vulnerabilities.
The vulnerabilities tracked by CVE-2026-20277 are related to protection mechanism failure issues that are grouped under the Common Weakness Enumeration (CWE) CWE-693. |
| A vulnerability in the Silicon One integration for Cisco Nexus 9000 Series Switches could allow an unauthenticated, remote attacker to execute code with root privileges.
This vulnerability exists because TCP ports 43210 and 43211 are accessible in the default Layer 3 (L3) virtual routing and forwarding (VRF). A successful exploit could allow the attacker to connect to an affected device and send crafted input that could be executed as code with root privileges. The exploitation of this vulnerability could also cause the S1HAL process to crash, which could cause the device to reload. |
| Local privilege-escalation vulnerabilities have been discovered in HPE Networking Fabric Composer. Successful exploitation of these vulnerabilities could allow a local attacker to achieve arbitrary code execution with root privileges on the underlying operating system of the affected system. |
| A sensitive information disclosure vulnerability exists in the API of HPE Networking Fabric Composer. Successful exploitation could allow an authenticated low privilege operator user to access data beyond what is authorized by the user's existing privilege level, potentially leading to further unauthorized access. |
| async-tar is a tar archive reading/writing library for async Rust. Prior to version 0.6.1, async-tar mis-applies a buffered PAX size extension to an intermediary extension header (a GNU longname L, a GNU longlink K, or a PAX x/g header) instead of to the next file entry. POSIX requires a PAX extended-header record set to describe the next file entry, never an intervening extension header. Because poll_next_raw (src/archive.rs) threads the buffered PAX records into the size computation of whatever raw header it reads next — and that header can be an intermediary L — the stream cursor is advanced by an attacker-chosen amount when the L body is consumed. The parser then desyncs relative to a POSIX-correct tar parser (e.g. GNU tar), reading subsequent bytes at the wrong block boundary. This issue has been patched in version 0.6.1. |
| A vulnerability in the API of HPE Networking Fabric Composer could allow an unauthenticated remote attacker to conduct a denial of service attack. Successful exploitation could allow an attacker to disrupt the availability of the affected interface. |
| Looking Glass is a modern, stateless network-diagnostic platform — a single self-contained Go binary that fronts a fleet of routers over SSH and exposes ping / traceroute / BGP lookups through a gRPC (ConnectRPC) API, an embedded SvelteKit web UI, and a lg-cli client. Prior to version 1.3.5, there is an OS Command Injection vulnerability resulting from an unanchored regular expression in the input validation layer. This issue has been patched in version 1.3.5. |
| Only self-managed Grafana instances with Auth Proxy authentication and identity caching enabled (sync_ttl greater than zero) are affected. The Auth Proxy cache key concatenated the username and forwarded identity attributes without a delimiter, so distinct identities could collide on one key. An authenticated user who shapes their own attributes to collide with a higher-privileged user's, while that user's cache entry is live, is authenticated as that user, up to Administrator (authentication bypass by spoofing). |
| When SAML IdP-initiated login is enabled in Grafana Enterprise, the SAML library skips validation of the InResponseTo field on all SAML responses, including SP-initiated logins. This removes anti-replay protection, allowing an attacker who obtains a valid signed SAML assertion to replay it and gain a session as the victim user. Only instances with the allow_idp_initiated SAML setting enabled are affected; this setting is off by default and Grafana OSS is not affected. |
| Jenkins 2.421 through 2.579 (both inclusive), LTS 2.426.1 through 2.568.2 (both inclusive) does not correctly perform permission checks in the Appearance configuration page, allowing attackers with Overall/Manage permission to modify Appearance configuration options they should not have access to. |
| A remote code execution vulnerability exists in the underlying operating system of HPE Networking Fabric Composer that could allow an unauthenticated remote attacker to run arbitrary commands on the underlying host if certain preconditions outside of the attacker's control are met. Successful exploitation could allow an attacker to execute arbitrary commands as a privileged user on the underlying operating system, leading to complete compromise of the HPE Networking Fabric Composer host. |
| An authenticated arbitrary file write vulnerability exists in AOS-CX. Successful exploitation could allow an authenticated malicious actor, under specific conditions outside the attacker's control and following a required action by another user, to create or modify arbitrary files and execute arbitrary commands as a privileged user on the underlying operating system. |
| Buffer overflow vulnerabilities exist in an underlying service of AOS-CX that could lead to an unauthenticated denial-of-service condition by sending specially crafted packets to the affected device. Successful exploitation of these vulnerabilities results in a disruption of normal operation of the underlying operating system. |
| Vulnerabilities have been identified in the API endpoint of AOS-CX switches that could potentially allow an unauthenticated remote actor to circumvent existing authentication controls. |
| Vulnerabilities have been identified in the operating system of AOS-CX switches that could potentially allow an unauthenticated remote actor to circumvent existing authentication controls. Successful exploitation could compromise system integrity and further expose sensitive information. |
| Vulnerability in Drupal Link content parser. This issue affects Link content parser versions: *.*. |
| A command injection vulnerability exists in the web-based management interface of HPE Networking Fabric Composer that could allow an unauthenticated remote attacker to run arbitrary commands on the underlying host if certain preconditions outside of the attacker's control are met. Successful exploitation could allow an attacker to execute arbitrary commands on the underlying operating system leading to complete system compromise. |
| An authenticated user with permission to query a SQL data source can bypass the fix for CVE-2026-33375 by injecting the timeGroup macro through a WHERE clause, which Grafana's regex-based macro parsing does not reject. Evaluating the injected macro causes uncontrolled memory consumption that can terminate the Grafana server process, resulting in a denial of service. The Microsoft SQL Server, PostgreSQL, and MySQL data sources are affected. |
| A flaw was found in insights-client. A compromised managed cluster, referred to as a 'spoke', can inject unencoded data into the Insights API URL path. This occurs because the ClusterID, which is controlled by the spoke, is used directly in the request path without proper validation or URL encoding. This vulnerability allows a malicious spoke to redirect authenticated requests to unintended API endpoints, potentially leading to information disclosure or unauthorized access. |
| A flaw was found in insights-client. When the application receives a non-200 response, it logs the request headers, which can include the cloud.openshift.com pull-secret token. A local user with access to pod logs on the hub could read this long-lived credential. This information disclosure could grant unauthorized access to Red Hat cloud services. |
