      "value": "conda-forge-webservices is the web app deployed to run conda-forge admin commands and linting. In versions prior to 2025.4.10, a race condition vulnerability has been identified in the conda-forge-webservices component used within the shared build infrastructure. This vulnerability, categorized as a Time-of-Check to Time-of-Use (TOCTOU) issue, can be exploited to introduce unauthorized modifications to build artifacts stored in the cf-staging Anaconda channel. Exploitation may result in the unauthorized publication of malicious artifacts to the production conda-forge channel. The core vulnerability results from the absence of atomicity between the hash validation and the artifact copy operation. This gap allows an attacker, with access to the cf-staging token, to overwrite the validated artifact with a malicious version immediately after hash verification, but before the copy action is executed. As the cf-staging channel permits artifact overwrites, such an operation can be carried out using the anaconda upload --force command. This vulnerability is fixed in 2025.4.10."

      "value": "conda-forge-webservices es la aplicaci\u00f3n web implementada para ejecutar los comandos de administraci\u00f3n y el linting de conda-forge. En versiones anteriores a la 2025.4.10, se identific\u00f3 una vulnerabilidad de condici\u00f3n de ejecuci\u00f3n en el componente conda-forge-webservices, utilizado en la infraestructura de compilaci\u00f3n compartida. Esta vulnerabilidad, categorizada como un problema de tiempo de verificaci\u00f3n a tiempo de uso (TOCTOU), puede explotarse para introducir modificaciones no autorizadas en los artefactos de compilaci\u00f3n almacenados en el canal de Anaconda cf-staging. Su explotaci\u00f3n puede resultar en la publicaci\u00f3n no autorizada de artefactos maliciosos en el canal de producci\u00f3n de conda-forge. La vulnerabilidad principal se debe a la ausencia de atomicidad entre la validaci\u00f3n del hash y la operaci\u00f3n de copia del artefacto. Esta brecha permite a un atacante, con acceso al token de cf-staging, sobrescribir el artefacto validado con una versi\u00f3n maliciosa inmediatamente despu\u00e9s de la verificaci\u00f3n del hash, pero antes de que se ejecute la copia. Dado que el canal de cf-staging permite la sobrescritura de artefactos, dicha operaci\u00f3n puede llevarse a cabo mediante el comando anaconda upload --force. Esta vulnerabilidad se corrigi\u00f3 en 2025.4.10."
