CVE-2026-48203
Full vulnerability record from the local CVENow database.
Description
Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection'), Improper Input Validation, Server-Side Request Forgery (SSRF) vulnerability in Apache Camel Solr component. The camel-solr producer copies Exchange message headers whose names begin with the SolrParam. prefix into the parameters of the Solr request, and headers whose names begin with the SolrField. prefix into the fields of the indexed Solr document. The prefix constants (SolrConstants.HEADER_PARAM_PREFIX / HEADER_FIELD_PREFIX) were the plain strings SolrParam. / SolrField.. Because these names do not start with the Camel / camel prefix, HttpHeaderFilterStrategy - which blocks only the Camel header namespace on the HTTP boundary - let them pass from an inbound HTTP request straight into the Exchange. In a route that bridges an HTTP consumer (for example platform-http) into a solr: producer, any HTTP client could therefore set SolrParam.* headers to inject arbitrary Solr request parameters - including shards or stream.url, which cause the Solr server to issue server-side requests to an attacker-chosen URL (server-side request forgery, for example to an internal service or a cloud metadata endpoint), or qt to reach administrative request handlers - and set SolrField.* headers to inject arbitrary fields into indexed documents. No credentials are required when the bridging consumer is unauthenticated. This issue affects Apache Camel: from 4.0.0 before 4.14.8, from 4.15.0 before 4.18.3, from 4.19.0 before 4.21.0. Users are recommended to upgrade to version 4.21.0, which fixes the issue. If users are on the 4.14.x LTS releases stream, then they are suggested to upgrade to 4.14.8. If users are on the 4.18.x releases stream, then they are suggested to upgrade to 4.18.3. After upgrading, routes that set Solr parameters or fields via the raw header prefixes must use CamelSolrParam. / CamelSolrField. instead of SolrParam. / SolrField.. For deployments that cannot upgrade immediately, strip the SolrParam.* and SolrField.* headers from any untrusted ingress before the solr: producer, and set the required Solr parameters and fields from a trusted source in the route.

"value": "Neutralización incorrecta de elementos especiales en la salida utilizada por un componente descendente (’Inyección’), Validación de entrada incorrecta, vulnerabilidad de falsificación de petición del lado del servidor (SSRF) en el componente Apache Camel Solr.\n\nEl productor camel-solr copia las cabeceras de mensaje de Exchange cuyos nombres comienzan con el prefijo SolrParam. en los parámetros de la petición Solr, y las cabeceras cuyos nombres comienzan con el prefijo SolrField. en los campos del documento Solr indexado. Las constantes de prefijo (SolrConstants.HEADER_PARAM_PREFIX / HEADER_FIELD_PREFIX) eran las cadenas de texto simples SolrParam. / SolrField.. Debido a que estos nombres no comienzan con el prefijo Camel / camel, HttpHeaderFilterStrategy - que bloquea solo el espacio de nombres de cabecera Camel en el límite HTTP - los dejó pasar de una petición HTTP entrante directamente al Exchange. En una ruta que conecta un consumidor HTTP (por ejemplo, platform-http) con un productor solr:, cualquier cliente HTTP podría, por lo tanto, establecer cabeceras SolrParam.* para inyectar parámetros de petición Solr arbitrarios - incluyendo shards o stream.url, que hacen que el servidor Solr emita peticiones del lado del servidor a una URL elegida por el atacante (falsificación de petición del lado del servidor, por ejemplo, a un servicio interno o a un punto final de metadatos de la nube), o qt para alcanzar manejadores de peticiones administrativos - y establecer cabeceras SolrField.* para inyectar campos arbitrarios en documentos indexados. No se requieren credenciales cuando el consumidor de puente no está autenticado.\nEste problema afecta a Apache Camel: desde 4.0.0 antes de 4.14.8, desde 4.15.0 antes de 4.18.3, desde 4.19.0 antes de 4.21.0.\n\nSe recomienda a los usuarios actualizar a la versión 4.21.0, que corrige el problema. Si los usuarios están en la rama de lanzamientos LTS 4.14.x, se les sugiere actualizar a 4.14.8. Si los usuarios están en la rama de lanzamientos 4.18.x, se les sugiere actualizar a 4.18.3. Después de actualizar, las rutas que establecen parámetros o campos Solr a través de los prefijos de cabecera sin procesar deben usar CamelSolrParam. / CamelSolrField. en lugar de SolrParam. / SolrField.. Para implementaciones que no pueden actualizarse inmediatamente, elimine las cabeceras SolrParam.* y SolrField.* de cualquier entrada no confiable antes del productor solr:, y establezca los parámetros y campos Solr requeridos desde una fuente confiable en la ruta."
