CRITICAL9.1

Published 2026-07-30 · Updated 2026-07-31 · Source cve@mitre.org

Description

Outstatic CMS <= 2.1.9 contains a hardcoded JWT signing secret. When the OST_TOKEN_SECRET environment variable is not set, the application falls back to the default value which is publicly visible in the source code repository. An unauthenticated remote attacker can exploit this by forging JWT session tokens with arbitrary user data and full administrative permissions.

CVE-2026-14483
The Realtyna Organic IDX plugin + WPL Real Estate plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 5.2.0 via the upload function. This is due to missing file type validation in the upload function, combined with a publicly accessible I/O endpoint authenticated solely by static, plugin-seeded API credentials that are identical across all installations. This makes it possible for unauthenticated attackers to upload files that may be executable, which makes remote code execution possible. The WPL I/O service endpoint is registered on the public WordPress init hook with no WordPress capability check, and the required api_key and api_secret values are static defaults seeded by the plugin's own SQL migration files, meaning any unauthenticated attacker who knows these publicly documented defaults can reach and exploit the vulnerable upload path.

CVE-2026-63223
CodeIgniter is a PHP full-stack web framework. Prior to 4.7.4, the is_image and mime_in upload validation rules do not independently enforce a safe client filename extension, allowing a remote attacker to upload executable content when an application preserves the client filename and stores uploads in a web-accessible script-enabled directory. Applications are impacted when they validate uploads using is_image or mime_in without an independent safe extension check (such as ext_in on patched versions), save uploaded files using the client-supplied filename, and place uploads in a web-accessible directory where PHP files can execute. This issue is fixed in version 4.7.4.

CVE-2026-63221
CodeIgniter is a PHP full-stack web framework. From 4.3.0 through 4.7.3, Query Builder deleteBatch() substitutes bound values from where() conditions into generated SQL while ignoring their escape flags, allowing user-controlled condition values to be interpreted as SQL. This affects only the deleteBatch() code path. Regular delete() operations escape where() binds correctly. This issue is fixed in version 4.7.4.
