CVE-2026-43575

CRITICAL
9.80 CVSS 3.1

OpenClaw versions 2026.2.21 before 2026.4.10 contain an authentication bypass vulnerability in the sandbox noVNC helper route that exposes interactive browser session credentials. Attackers can access the noVNC helper route without bridge authentication to gain unauthorized access to the interactive browser session.

CVE-2026-35579

CRITICAL
9.80 CVSS 3.1

CoreDNS is a DNS server written in Go. In versions prior to 1.14.3, the gRPC, QUIC, DoH, and DoH3 transport implementations incorrectly handle TSIG authentication. For gRPC and QUIC, the server checks whether the TSIG key name exists in the configuration but never calls dns.TsigVerify() to validate the HMAC. If the key name matches a configured key, the tsigStatus field remains nil and the tsig plugin treats the request as successfully authenticated regardless of the MAC value. For DoH and DoH3, the issue is more severe: the DoHWriter.TsigStatus() method unconditionally returns nil, and the server never inspects the TSIG record at all. Any request containing a TSIG record is treated as authenticated over DoH and DoH3, even if the key name is invalid and the MAC is arbitrary. An unauthenticated network attacker can exploit this to bypass TSIG-protected functionality such as AXFR/IXFR zone transfers, dynamic DNS updates, or other TSIG-gated plugin behavior. The DoH and DoH3 variants have a lower exploitation bar because the attacker does not need to know a valid TSIG key name. This issue has been fixed in version 1.14.3. As a workaround, disable gRPC, QUIC, DoH, and DoH3 listeners where TSIG authentication is required, or restrict network-level access to affected transport ports to trusted sources only.

CVE-2026-34084

CRITICAL
9.80 CVSS 3.1

PhpSpreadsheet is a library for reading and writing spreadsheet files. In versions 1.30.2 and earlier, 2.0.0 through 2.1.14, 2.2.0 through 2.4.3, 3.3.0 through 3.10.3, and 4.0.0 through 5.5.0, when the filename argument to IOFactory::load() is user-controlled, an attacker can supply a PHP stream wrapper path (such as phar://, ftp://, or ssh2.sftp://) that passes the is_file() check in File::assertFile(). The phar:// wrapper triggers deserialization of the PHAR metadata, which can lead to remote code execution if a suitable gadget chain is available in the application. The ftp:// and ssh2.sftp:// wrappers can be used for server-side request forgery. This issue has been fixed in versions 1.30.3, 2.1.15, 2.4.4, 3.10.4, and 5.6.0.

CVE-2026-5294

CRITICAL
9.80 CVSS 3.1

The Geeky Bot plugin for WordPress is vulnerable to Missing Authorization in versions up to, and including, 1.2.2. This is due to a nopriv AJAX route allowing attacker-controlled model/function dispatch and reaching a plugin installer helper that downloads and unzips attacker-supplied ZIP files into wp-content/plugins/. This makes it possible for unauthenticated attackers to perform arbitrary plugin installation and achieve remote code execution.

Missing Authorization

CVE-2025-13618

CRITICAL
9.80 CVSS 3.1

The Mentoring plugin for WordPress is vulnerable to privilege escalation in all versions up to, and including, 1.2.8. This is due to the plugin not properly restricting the roles that users can register with in the mentoring_process_registration() function. This makes it possible for unauthenticated attackers to register with administrator-level user accounts.

Improper Privilege Management
WAF: Low

CVE-2026-5722

CRITICAL
9.80 CVSS 3.1

The MoreConvert Pro plugin for WordPress is vulnerable to Authentication Bypass in all versions up to, and including, 1.9.14. This is due to the guest waitlist verification flow not invalidating or regenerating verification tokens when the customer email address is changed. This makes it possible for unauthenticated attackers to authenticate as existing users, including administrators, by obtaining a valid guest verification token for an attacker-controlled email, changing the same guest customer email to the target account email through the public waitlist flow, and then using the original verification link.

CVE-2026-42238

CRITICAL
9.80 CVSS 3.1

Nginx UI is a web user interface for the Nginx web server. Prior to version 2.3.8, nginx-ui exposes a backup restore endpoint (POST /api/restore) that is completely unauthenticated during the first 10 minutes after process startup on any fresh installation. An unauthenticated remote attacker can upload a crafted backup archive that overwrites the application's configuration file (app.ini) and SQLite database. Because the attacker controls the restored app.ini, they can inject an arbitrary OS command into the TestConfigCmd setting. After the application automatically restarts to apply the restored config, a single follow-up request triggers that command as the user running nginx-ui — typically root in Docker deployments. This issue has been patched in version 2.3.8.

CVE-2026-42235

CRITICAL
9.60 CVSS 3.1

n8n is an open source workflow automation platform. Prior to versions 1.123.32, 2.17.4, and 2.18.1, an unauthenticated attacker could register a malicious MCP OAuth client with a crafted client_name. If a victim user authorized the OAuth consent dialog and a second user subsequently revoked that access, a toast notification would render the injected script. Clicking the link would execute arbitrary JavaScript in the victim's authenticated n8n browser session, enabling credential and session token theft, workflow manipulation, or privilege escalation. This issue has been patched in versions 1.123.32, 2.17.4, and 2.18.1.

CVE-2026-42233

CRITICAL
9.80 CVSS 3.1

n8n is an open source workflow automation platform. Prior to versions 1.123.32, 2.17.4, and 2.18.1, a flaw in the Oracle Database node's select operation allowed user-controlled input passed into the Limit field via expressions to be interpolated directly into the SQL query without sanitization or parameterization. In workflows where external input is passed into the Limit field (e.g., from a webhook), an attacker could inject arbitrary SQL and exfiltrate data from the connected Oracle database. This issue has been patched in versions 1.123.32, 2.17.4, and 2.18.1.

CVE-2026-30893

CRITICAL
9.90 CVSS 3.1

Wazuh is a free and open source platform used for threat prevention, detection, and response. From version 4.4.0 to before version 4.14.4, a path traversal vulnerability in Wazuh's cluster synchronization extraction routine allows an authenticated cluster peer to write arbitrary files outside the intended extraction directory on other cluster nodes. This can be escalated to code execution in the Wazuh service context by overwriting Python modules loaded by Wazuh components (proof of concept available as separate attachment). In deployments where the cluster daemon runs with elevated privileges, system-level compromise is possible. This issue has been patched in version 4.14.4.
