♻️ Validate Server Sent Event fields to avoid applications from sending broken data ## Pull Request <!-- Please start with a GitHub Discussion. Once a team member asks you to open a PR, create it and link the discussion here. Obvious typo fixes can be made in a PR without starting a discussion. --> Discussion: <!-- Link to the GitHub Discussion --> ## Description ♻️ Validate Server Sent Event fields to avoid applications from sending broken data This was reported multiple times as a "vulnerability" by users probably using automated AI tools, with the argument that if input was taken from the request and passed directly to an event unfiltered, it could break the client. If an app sets an `id` or `event` with multi-line content, I would consider that app broken, and probably the app itself vulnerable to something, not FastAPI. With this change, if any app sets invalid multi-line values (sourced from unfiltered input or in any other way), FastAPI will make it a server error (which it is, as the app is sending invalid data). I don't think the code before this PR has a bug, less a vulnerability. This change is mainly a quality of life improvement to prevent badly written apps from shooting themselves in the foot by passing unsanitized data directly to a SSE. <!-- Write the description of your PR here --> ## AI Disclaimer <!-- If using AI, write here the prompt and model used --> Codex with GPT-5.5 <details> <summary>AI transcript</summary> <!-- Paste here the entire AI transcript --> </details> ## Checklist - [ ] This PR is an obvious typo fix, or it links to a GitHub Discussion for the proposed code change. - [x] I added tests for the change. - [x] The new or updated tests fail on the main branch and pass on this PR. - [x] Coverage stays at 100%. - [x] The documentation explains the change if needed.
