Technical Analysis

llhttp 8.1.1 has two undisclosed request smuggling vulnerabilities. aiohttp versions prior to 3.8.6 include this vulnerable llhttp version, making aiohttp indirectly vulnerable. Black versions from 19.10b0_3 to before 23.10.0 depend on these vulnerable aiohttp versions. The issue is fixed by upgrading llhttp to version 9 or later, which is included in aiohttp 3.8.6 and above.

Potential Impact

Potential for HTTP request smuggling attacks exists in affected versions due to the vulnerable llhttp dependency. No known exploits in the wild have been reported. The impact could allow attackers to interfere with HTTP request processing, but specific impact details are not disclosed.

Mitigation Recommendations

Upgrade aiohttp to version 3.8.6 or later, which includes llhttp 9 or above, to remediate the vulnerability. Consequently, upgrade Black to version 23.10.0 or later to ensure the vulnerable dependency is replaced. Monitor official llhttp advisories for further details.
