CVE-2023-20576

The Popup Builder plugin for WordPress in versions up to and including 4.4.5 does not properly verify that a user is authorized to perform an action. An unauthenticated attacker can trash all published popups on the site with a single GET request, amplified by a second flaw in SGPopup::find() that causes the trash branch to fire against every popup simultaneously.

The WP Booking System – Booking Calendar plugin for WordPress in versions up to and including 2.1.0.5 lacks a capability check in the wpbs_action_ajax_calendar_remove_note() function. An authenticated attacker with Subscriber-level access or above can delete arbitrary calendar notes belonging to any calendar.

The PDF Invoice for WooCommerce + Drag and Drop Template Builder plugin in versions up to and including 7.1.1 is vulnerable to PHP Object Injection via the 'customer_note' parameter. The checkout field is insufficiently sanitized and passed to unserialize() without validation, allowing unauthenticated attackers to execute code on the server.

The pow-auth Assent library's Sign in with Apple strategy trusts the browser-supplied 'user' parameter, which the client controls. That parameter is merged over the verified ID token claims, allowing an unauthenticated remote attacker to impersonate another user. Affects versions from 0.1.25 before 0.3.2.

In TAKO AI Agent for Okta prior to 3.0.1-beta, the POST /api/auth/setup endpoint allows an unauthenticated network attacker to create the first administrator account before the legitimate owner completes initial setup. The initial_setup function checks only the is_setup flag and requires no authentication, bootstrap token, or network restriction, and the default configuration listens on 0.0.0.0:8001.

MoLing in SSE mode (started with -l) does not authenticate requests to the /sse and /message endpoints, and the mcp-go dependency sets Access-Control-Allow-Origin: *. A malicious web page can open a cross-origin EventSource to /sse, read the sessionId, and send unauthorized MCP tool calls via /message, potentially leading to file read/write or command execution. The issue is fixed in version 0.5.0.

In ThingLinks before 1.4.0, the /groovyScriptTest/registerScript endpoint accepts user-supplied Groovy script content and passes it to an unsandboxed compilation and loading flow. An authenticated attacker can supply code that is compiled and executed on the server, leading to remote server-side code execution. The issue affects the rule engine's Groovy script test/register flow and is fixed in version 1.4.0.

In ThingLinks before 1.4.0, an unauthenticated SQL injection vulnerability exists in the TDengine TDS APIs. JSON field values submitted to /anyUser/tds/insertTableData reach unsafe SQL construction in the TDS mapper, allowing a remote unauthenticated attacker to tamper with TDengine time-series data, including inserting unintended rows or overwriting existing readings. The issue is fixed in version 1.4.0.

The ssl_verify_fun library (deadtrickster) improperly validates certificates with host mismatch because try_match_wildcard/4 in src/ssl_verify_hostname.erl anchors only the text before and after the * in an identifier such as f*.example.net. This causes the wildcard to also consume dots, so the certificate is accepted for f.evil.example.net, and *.168.1.1 matches the IP literal 192.168.1.1. The issue affects versions from 1.0.1 before 1.1.8.

Stack-based buffer overflow and missing authorization in Thales Sentinel Keys Server on Windows. The server does not check the length of the first field in an HTTP request, allowing an attacker to send a crafted request and potentially achieve remote code execution as NT AUTHORITY\SYSTEM.
