**Name of the Vulnerable Software and Affected Versions** Symbolicator versions 0.3.3 through 21.12.1 **Description** The issue allows an attacker to make Symbolicator send GET HTTP requests to arbitrary URLs with internal IP addresses by using an invalid protocol. The responses of those requests could be exposed via Symbolicator's API. In affected Sentry instances, the data could be exposed through the Sentry API and user interface if the attacker has a registered account. **Recommendations** For Symbolicator versions 0.3.3 through 21.12.1, update to Symbolicator release 23.12.1 or later. For Sentry self-hosted, update to Sentry self-hosted release 23.12.1 or later. If updating is not possible, consider the following mitigations: - Disable JS processing by toggling the option `Allow JavaScript Source Fetching` in `Organization Settings > Security & Privacy`. - Disable all untrusted public repositories under `Project Settings > Debug Files`. - Alternatively, if JavaScript and native symbolication are not required, disable Symbolicator completely in `config.yml`.
