CWE-20 26/05/2026
Servidor Web Algernon: Busca Ascendente de handler.lua Leva a Execução Remota de Código
Algernon é um pequeno servidor web autocontido, escrito em Go puro. Antes da versão 1.17.7, quando o Algernon recebe uma requisição para qualquer caminho de URL que resolva para um diretório sem arquivo de índice, DirPage percorre diretórios ancestrais — além da raiz configurada do servidor — procurando um arquivo chamado handler.lua para executar como manipulador da requisição. O laço termina somente após 100 passos ancestrais ou quando filepath.Dir retorna ., portanto, em qualquer caminho absoluto de raiz do servidor, a busca alcança a raiz do sistema de arquivos (/ em Unix, letra de unidade no Windows). O primeiro handler.lua encontrado é carregado no interpretador Lua com toda a API do Algernon exposta — incluindo run3(), httpclient, os.execute, io.popen, PQ, MSSQL, acesso bruto ao sistema de arquivos e o banco de dados userstate. Qualquer processo que possa gravar handler.lua em qualquer diretório pai da raiz do servidor obtém execução remota de código pré-autenticada na próxima requisição HTTP. Isso é alcançável sem autenticação — a busca ocorre antes que a verificação de permissão retorne um resultado (o sistema de permissões só controla prefixos de URL, não a etapa de resolução do manipulador), e qualquer URL apontando para um diretório sem índice dispara a busca. Em uma instalação padrão nova do Algernon, a requisição GET / é suficiente. Esta vulnerabilidade está corrigida na versão 1.17.7.

e107: Host Header Injection in e107 password reset enables phishing
e107 is a content management system (CMS). Prior to 2.3.4, a Host Header Injection vulnerability in the password reset page allows attackers to manipulate the Host header to generate password reset links pointing to attacker-controlled domains. This can lead to phishing attacks, account takeover, or other security risks. The severity is high, as the vulnerability affects a critical function related to user authentication. This vulnerability is fixed in 2.3.4.

TypeBot: SSRF Protection Bypass via DNS-Resolved Hostnames in Webhook / HTTP Request Validation
TypeBot is a chatbot builder tool. In versions prior to 3.16.0, SSRF protection for Webhook / HTTP Request blocks validates only the URL string, blocked hostname literals, and literal IP formats. It does not resolve DNS before allowing the request. As a result, a hostname such as ssrf-repro.example that resolves to 127.0.0.1, 169.254.169.254, or RFC1918/private space passes validation and is later fetched by the backend HTTP client. This enables server-side request forgery to loopback, cloud metadata, and private network targets. This issue has been resolved in version 3.16.0.

Yii 2: Local file inclusion via view parameter name collision
Yii 2 is a PHP application framework. Versions 2.0.54 and prior contain flawed logic in the core view rendering method View::renderPhpFile() that leads to Local File Inclusion. The function calls extract($_params_, EXTR_OVERWRITE) before the require statement that loads the view file. As a result, a caller-controlled _file_ key in the $params array overwrites the internal local variable specifying which file to include, potentially enabling RCE if an attacker can write PHP files through a separate primitive, as well as information disclosure. This issue has been fixed in version 2.0.55.

Invalid handling of CLASS != IN
Multiple flaws have been identified in `named` related to the handling of DNS messages whose CLASS is not Internet (`IN`) — for example, `CHAOS` or `HESIOD`, or DNS messages that specify meta-classes (`ANY` or `NONE`) in the question section. Specially crafted requests reaching the affected code paths — recursion, dynamic updates (`UPDATE`), zone change notifications (`NOTIFY`), or processing of `IN`-specific record types in non-`IN` data — can cause assertion failures in `named`.
This issue affects BIND 9 versions 9.11.0 through 9.16.50, 9.18.0 through 9.18.48, 9.20.0 through 9.20.22, 9.21.0 through 9.21.21, 9.11.3-S1 through 9.16.50-S1, 9.18.11-S1 through 9.18.48-S1, and 9.20.9-S1 through 9.20.22-S1.

Remote Code Execution (RCE) via Zip Slip in Plugin Upload Mechanism
FacturaScripts is an open source accounting and invoicing software. Versions 2026 and below contain a critical vulnerability in the Plugins::add() function. The system fails to properly validate the file paths within uploaded ZIP archives. This allows an attacker to perform a Zip Slip attack, leading to Arbitrary File Write and Remote Code Execution (RCE) by overwriting sensitive .php files outside the designated plugins directory. The vulnerability is located in Plugins.php. While the testZipFile function attempts to validate that the ZIP contains only one root folder, it does not sanitize or validate the individual file paths within that folder. An attacker can bypass this check by naming a file ValidPluginName/../../shell.php. The explode function will see ValidPluginName as the root folder, satisfying the count($folders) != 1 check. However, during extraction, the ../../ sequence triggers a path traversal, allowing the file to be written anywhere the web server has permissions the root directory. This issue is fixed in version 2026.1.

Open WebUI: Cross-Site Request Forgery (CSRF) via Image URL Manipulation
Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to 0.9.3, an application-wide Cross-Site Request Forgery (CSRF) vulnerability was found Open-WebUl's image uploading functionality. An attacker can set an image URL to a malicious endpoint, allowing them to perform actions on behalf of a victim user. Any authenticated user can exploit this vulnerability, and any user who views the compromised image (e.g., a profile picture) will unknowingly send a GET request to the attacker-controlled URL. This can lead to cookie theft, denial of service (DoS), or other malicious actions. This vulnerability is fixed in 0.9.3.
