CVE-2026-108587
The 10Web Booster – Website speed optimization, Cache & Page Speed optimizer plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 2.34.10 via the compressCustom function. This is due to missing file type validation and extension filtering on the page_id parameter, combined with a world-readable leaked nonce that bypasses authentication checks. This makes it possible for unauthenticated attackers to upload files that may be executable, which makes remote code execution possible. This exploit chain requires obtaining the plugin's REST nonce (tenwebio_rest), which is automatically serialized to a world-readable file under wp-content/uploads/ whenever a bulk optimisation batch pauses; because the nonce is generated in a cron/loopback context with a user ID of 0, it is valid for unauthenticated visitors.

CVE-2026-110911
Wheels 1.1.8 through 4.1.1 allows SQL injection when caller-supplied quoted values are parsed again as SQL by dynamic finders (such as findOneByEmail), the query builder's where(property, value) and where(property, operator, value), string/UUID-key lookup paths (findByKey, updateByKey, deleteByKey and findOrCreateBy...), and validatesUniquenessOf. The parser incorrectly treats a doubled single quote as the end of a literal. Applications passing request data to these APIs can expose authentication, password-reset or token lookups, and data to unauthorized access; numeric-column values are not affected. There is a similar concern for query-builder whereBetween() in 4.0.0 through 4.1.1: string/date bounds can alter SQL on MySQL/MariaDB with backslash escaping enabled. This is fixed in 4.1.2.

CVE-2026-110862
Better Auth from 1.4.0-beta.18 before 1.7.7 contains an authentication bypass vulnerability that allows unauthenticated attackers to sign in as other users by reusing OAuth state values as Magic Link tokens. Attackers can start an OAuth sign-in with a victim's email and submit the returned state to Magic Link verification, gaining sessions or creating falsely email-verified accounts.

CVE-2026-55684
WeGIA is a web manager for charitable institutions. Prior to 3.8.6, the unauthenticated web/html/socio/sistema/cadastro_cobrancas_geracao.php endpoint accepts form-encoded POST data through extract($_REQUEST) and interpolates codigo, descricao, data_emissao, data_vencimento, data_pagamento, valor, valor_pago, status, link_cobranca, link_boleto, linha_digitavel, and id_socio into a raw INSERT statement. Numeric parameters are unquoted and unvalidated, while string parameters can break out of their single-quoted SQL context. A remote attacker can execute arbitrary SQL to read or modify billing, member, employee, permission, and credential data or to delete database tables. This issue is fixed in version 3.8.6.

CVE-2026-55683
WeGIA is a web manager for charitable institutions. Prior to 3.8.6, the unauthenticated web/html/socio/sistema/cadastro_cobranca.php endpoint accepts POST input through extract($_REQUEST) and directly incorporates valor, valor_pago, id_pessoa, id_socio, and id_sociotipo into UPDATE, INSERT, and SELECT statements without prepared statements. A remote attacker can use the affected parameters to execute arbitrary SQL that reads or modifies WeGIA database content, including billing records and credential data. The same SQL access can delete or truncate tables, causing loss of application data. This issue is fixed in version 3.8.6.
