**Nome do Software Vulnerável e Versões Afetadas** Kdenlive versões anteriores a 26.04.1 **Descrição** Existe um problema onde o software permite a injeção de parâmetros de proxy perigosos quando um arquivo de projeto controlado por um invasor é utilizado. **Recomendações** Atualize para a versão 26.04.1.

**Name of the Vulnerable Software and Affected Versions** Feathersjs versions 5.0.39 and below **Description** Feathersjs is a framework used for building web APIs and real-time applications. A flaw exists where the redirect query parameter is added to the base origin without proper validation. This allows attackers to steal access tokens through URL authority injection, potentially leading to full account takeover. The application builds the redirect URL by combining the base origin with a user-provided redirect parameter. This is exploitable when origins do not end with a forward slash (/). An attacker can provide a malicious redirect value, such as `@attacker.com`, resulting in a URL like `https://target.com@attacker.com#access token=...`. The browser then interprets `attacker.com` as the host, enabling the attacker to obtain the victim's access token and impersonate them. **Recommendations** Update to version 5.0.40 or later.

**Name of the Vulnerable Software and Affected Versions** Feathersjs versions 5.0.39 and below **Description** Feathersjs is a framework used for building web APIs and real-time applications. A flaw in origin validation, specifically using the `startsWith()` function for comparison, allows attackers to bypass origin checks. This bypass is possible by registering a domain that shares a common prefix with an allowed origin. The `getAllowedOrigin()` function inadequately validates the prefix of the Referer header against allowed origins. An attacker can initiate the OAuth flow from an unauthorized origin and potentially steal tokens, leading to full account takeover. **Recommendations** Update to version 5.0.40 or later.

**Name of the Vulnerable Software and Affected Versions** Feathersjs versions 5.0.39 and below **Description** Feathersjs is a framework used for building web APIs and real-time applications. Versions 5.0.39 and below store all HTTP request headers in a session cookie that is signed but not encrypted. This can expose internal proxy/gateway headers to clients. The OAuth service stores the complete headers object in the session, which is then persisted using cookie-session and base64-encoded. While the cookie is signed, the data is readable by decoding the base64 value. In certain deployment configurations, such as those behind reverse proxies or API gateways, this can lead to the disclosure of sensitive internal infrastructure details like API keys, service tokens, and internal IP addresses. The issue involves the storage of sensitive information in the session cookie, specifically impacting the handling of HTTP request headers and OAuth service data. **Recommendations** Update to version 5.0.40 or later.

Nome do Software Vulnerável e Versões Afetadas: Versões do HAProxy de 2.2 a 3.1.6 Descrição: O problema está relacionado a um estouro de buffer baseado em heap em certas configurações incomuns, devido ao tratamento incorreto da substituição de múltiplos padrões curtos por um mais longo. Isso ocorre na função sample conv regsub. Recomendações: Para as versões do HAProxy de 2.2 a 3.1.6, considere atualizar para uma versão que inclua uma correção para o problema de estouro de buffer baseado em heap na sample conv regsub. No momento, não há informações sobre uma versão mais recente que contenha uma correção para esta vulnerabilidade.
