QAnything 2.0.0 contains an authentication bypass vulnerability in the /api/local_doc_qa/get_file_base64 and /api/local_doc_qa/get_doc endpoints that allows unauthenticated attackers to access any uploaded file or document. Attackers can enumerate file identifiers through unauthenticated endpoints and retrieve base64-encoded files or parsed document chunks without ownership verification to disclos…

WWBN AVideo contains a server-side request forgery filter bypass vulnerability in the isSSRFSafeURL function that fails to normalize NAT64 addresses written in hexadecimal form. Attackers can bypass SSRF protections by supplying hex-encoded NAT64 addresses like 64:ff9b::a9fe:a9fe to reach cloud metadata services and loopback interfaces.

fast-uri is a URI parser for Node.js. During parsing it runs a legacy decoding pass over the scheme component and never re-escapes the result, and serialization writes the scheme back out verbatim, unlike the host component which is re-escaped. As a result an input whose scheme carries percent-encoded slashes parses as a scheme with no authority, so the parsed host and error are both undefined, ye…

fast-uri is a URI parser for Node.js. It decodes percent escapes in a hostname during parsing and then decodes the parsed hostname a second time during authority recomposition, so a single call to normalize or resolve can turn nested percent-encoded input into a different network destination such as a loopback hostname or address. For example, a doubly encoded host that spells out a loopback name …

Vulnerabilidad de referencia nula en kin-openapi afecta validación de solicitudes

kin-openapi, biblioteca Go para procesar archivos OpenAPI, presenta una vulnerabilidad (CVSS 7.5) en versiones 0.10.0 a 0.141.0 que permite un acceso a memoria nula cuando procesa campos escalares malformados en solicitudes multipart/form-data. Un atacante puede causar bloqueo de servicio contra aplicaciones que usan esta biblioteca para validación de APIs. Empresas en LATAM con servicios REST y microservicios basados en Go están en riesgo si implementan kin-openapi sin parchear.
