AIOHTTP is Vulnerable to Deserialization of Untrusted Data
### Summary Using ``CookieJar.load()`` with untrusted input may allow arbitrary code execution. ### Impact Most applications using this function will be doing so with the user's own data, so this is unlikely to affect many applications. ### Workaround If an application does allow attacker controlled files to be loaded, a workaround on older releases would be to sanitise the files before loading. ----- Patch: https://github.com/aio-libs/aiohttp/commit/dcf40f30637e8752c76781cf6703b5a236749a00
