CVE-2026-19820 1 Backblaze 1 Backblaze 2026-09-01 N/A
A vulnerability in the Backblaze Client allows a local user to make the system not bootable by creating a link from Backblaze's folder to Windows OS system files during a backup. Successful exploitation requires an administrator-level system change that results in the absence of specific Windows OS security controls. This vulnerability is due to improper link resolution.
CVE-2026-48932 1 Nodejs 1 Nodejs 2026-09-01 N/A
A flaw in Node.js HTTP client can cause a request desynchronization for Node.js-based forwarding proxies that rebuild outbound headers from the visible `IncomingMessage` headers while piping the original body to a reused backend connection. Node.js can omit headers beyond `maxHeadersCount` / `maxHeaderPairs` from `req.headers`, `req.rawHeaders`, and `req.headersDistinct`, while still using those omitted headers internally for HTTP message framing. In particular, `Content-Length` can be hidden from userland while the request body is still delivered. This vulnerability affects all supported release lines: **Node.js 22**, **Node.js 24**, and **Node.js 26**.
CVE-2026-18488 2 Creativethemes, Wordpress 2 Blocksy Companion, Wordpress 2026-09-01 6.4 Medium
The Blocksy Companion plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'tagName' Block Attribute (blocksy/dynamic-data) in all versions up to, and including, 2.1.51 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Sandbox escape in the Remote Settings Client component. This vulnerability was fixed in Firefox 154, Thunderbird 154, Firefox ESR 115.40, Firefox ESR 140.15, and Firefox ESR 153.2.
CVE-2026-84061 1 Zhongyu09 1 Openchatbi 2026-09-01 6.3 Medium
A security flaw has been discovered in zhongyu09 OpenChatBI up to 0.3.0. Affected by this vulnerability is the function _validate_sql_safety of the file openchatbi/text2sql/generate_sql.py. Performing a manipulation results in sql injection. The attack can be initiated remotely. Versions v0.2.0 through v0.2.2 have no SQL safety validation at all, while v0.3.0 introduced a validator and v1.0.0b1/main kept the same incomplete one with an optional stricter mode. The vendor was contacted early about this disclosure but did not respond in any way.
CVE-2026-10579 1 Redhat 2 Jboss Enterprise Application Platform, Jboss Enterprise Application Platform Els 2026-09-01 9.8 Critical
A flaw was found in Picketlink Federation SAML; the unsolcited response handler would accept forged assertions with no verification or validation, permitting an unauthed attacker to authenticate as any principal in any role. This could lead to information disclosure, access to restricted operations, or other flaws.
CVE-2026-18649 1 Redhat 3 Enterprise Linux, Rhel E4s, Rhel Eus 2026-09-01 7.5 High
A flaw was found in the GStreamer gst-plugins-good package. The rtph264depay and rtph265depay RTP depayloader elements do not enforce a maximum size limit on the reassembly buffer used during fragmented RTP packet processing. A remote, unauthenticated attacker can send a continuous stream of RTP fragments without ever transmitting an end-of-fragment marker, causing the reassembly buffer to grow without bound until process memory is exhausted. This results in a denial of service through process termination.
CVE-2026-84200 1 Kyverno 1 Kyverno 2026-09-01 9 Critical
Kyverno versions v1.9.0 through v1.12.7 contain a policy exception handling flaw. When a policy in enforce mode is combined with two PolicyExceptions, the less restrictive exception takes precedence, allowing an attacker to bypass the policy by crafting a resource name that matches the second exception's name pattern (e.g., '*ingress*'). This can be used to circumvent policies such as one blocking hostPath volumes. Fixed in v1.13.0.
CVE-2026-84199 1 Kyverno 1 Kyverno 2026-09-01 7.7 High
Kyverno before 1.16.2 contains a server-side request forgery (SSRF) vulnerability in the APICall feature. The URL field in a Policy's ServiceCall configuration is not validated, so a user with namespace-level Policy creation permissions can direct Kyverno to make HTTP requests to arbitrary internal resources (e.g., cloud metadata endpoints such as 169.254.169.254 or other tenants' resources). Because Kyverno executes these requests using its cluster-wide high-privilege ServiceAccount (a Confused Deputy problem), the responses—potentially including other tenants' secrets and cloud IAM credentials—are returned in the PolicyReport and can be read by the attacker, breaking multi-tenant isolation.
CVE-2026-84196 1 Kyverno 1 Kyverno 2026-09-01 7.7 High
Kyverno before 1.18.0 contains a server-side request forgery vulnerability in apiCall.service.url that allows authenticated users to send arbitrary HTTP requests by injecting user-controlled input through variable substitution. Attackers can target internal services, cloud metadata endpoints, and loopback addresses, with response data reflected in admission error messages enabling non-blind data exfiltration.
CVE-2026-84194 1 Librenms 1 Librenms 2026-09-01 N/A
LibreNMS versions >= 23.10.0 and < 26.2.0 (fixed in 26.4.0) contain an authenticated OS command injection vulnerability in libvirt discovery. When libvirt support is enabled (enable_libvirt=true), the device hostname ($this->getDevice()->hostname) is concatenated into shell commands (ssh, virsh list/dumpxml/domstate) in VminfoLibvirt.php and passed to exec() without escapeshellarg() or argument separation. An authenticated admin can set a crafted device hostname to inject arbitrary OS commands, leading to remote code execution in the discovery worker context.
CVE-2026-84193 1 Librenms 1 Librenms 2026-09-01 N/A
LibreNMS through 26.2.0 contains a stored cross-site scripting vulnerability in legacy PHP template pages that render unescaped SNMP-sourced data fields including BGP peer descriptions, VRF names, process information, and SLA tags. Attackers with device management access or network access to enroll a rogue SNMP device can inject malicious JavaScript that executes when admins view affected routing and device pages, enabling credential theft and CSRF token exfiltration.
CVE-2026-84192 1 Librenms 1 Librenms 2026-09-01 7.1 High
LibreNMS before 26.3.1 contains a stored cross-site scripting vulnerability in legacy PHP templates that output SNMP-sourced and syslog-sourced data without escaping. An attacker who controls a monitored network device can inject arbitrary JavaScript through SNMP interface descriptions or syslog program fields that executes when authenticated users view affected pages.
CVE-2026-84191 1 Librenms 1 Librenms 2026-09-01 6.1 Medium
LibreNMS before 26.5.0 contains stored cross-site scripting vulnerabilities in VRF display pages where mplsVpnVrfDescription, vrf_name, and mplsVpnVrfRouteDistinguisher fields from SNMP polling are rendered without sanitization. Attackers controlling a monitored network device can inject arbitrary JavaScript through SNMP responses that executes in the browser of any user viewing VRF-related pages.
CVE-2026-84189 1 Librenms 1 Librenms 2026-09-01 8.1 High
LibreNMS through 26.4.0 renders JSON fields (name, ip, model, author, commit message) returned by the admin-configurable Oxidized integration URL (oxidized.url) into the device showconfig page without applying htmlspecialchars(). An administrator who points the Oxidized URL at an attacker-controlled server (SSRF) can cause it to return malicious JSON, resulting in stored/persistent cross-site scripting affecting all users who view any device's showconfig tab. Fixed in 26.7.0.
CVE-2026-84188 1 Librenms 1 Librenms 2026-09-01 4.8 Medium
LibreNMS versions <= 26.4.0 contain a stored cross-site scripting vulnerability in the graph_descr.<graphtype> configuration settings, which are echoed verbatim without HTML escaping in includes/html/pages/graphs.inc.php. An administrator can store a malicious HTML payload that executes in the browser of any authenticated user who views the affected graph type. The issue is fixed in version 26.7.0.
CVE-2026-84187 1 Wwbn 1 Avideo 2026-09-01 8.2 High
AVideo contains a missing authentication vulnerability in plugin/Live/on_publish.php that allows unauthenticated attackers to mark arbitrary scheduled broadcasts as failed by sending crafted POST requests with schedule identifiers. Attackers can exploit the unguarded RTMP callback endpoint to modify scheduled broadcast status fields by supplying fabricated stream keys matching the pattern -ps-<N>, silently canceling any scheduled live broadcast without credentials or authorization.
