GHSA-v6wp-4m6f-gcjg
`aiohttp` Open Redirect vulnerability (`normalize_path_middleware` middleware)
Packages
Details
As written in the advisory (Markdown source, shown as plain text).
### Impact
Open redirect vulnerability — a maliciously crafted link to an aiohttp-based web-server could redirect the browser to a different website.
It is caused by a bug in the `aiohttp.web_middlewares.normalize_path_middleware` middleware.
### Patches
This security problem has been fixed in v3.7.4. Upgrade your dependency as follows:
[`pip install aiohttp >= 3.7.4`]
### Workarounds
If upgrading is not an option for you, a workaround can be to avoid using `aiohttp.web_middlewares.normalize_path_middleware` in your applications.
