An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2024-42367 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- aiohttp (PyPI): affected from 3.10.0b1; fixed in 3.10.2\n- aiohttp (PyPI): affected from 3.10.0b1; fixed in 3.10.2\n- aiohttp (PyPI): affected from 3.10.0b1; fixed in 3.10.2\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2024-42367/ (Markdown: https://insights.sbomify.com/CVE-2024-42367/index.md)","id":"CVE-2024-42367","markdown":"https://insights.sbomify.com/CVE-2024-42367/index.md","name":"CVE-2024-42367","record":{"aliases":["AZL-47754","AZL-47763","DEBIAN-CVE-2024-42367","GHSA-jwhx-xcg6-8xhj","OESA-2024-2254","PYSEC-2026-1108","SUSE-SU-2024:3110-1","openSUSE-SU-2024:14280-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Python HTTP library","requires_auth":"none","summary":"Attackers can read arbitrary files outside the root directory via symlinked compressed files in aiohttp static routes.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"aiohttp","vendor":"aiohttp"}],"cvss":{"score":4.8,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-61","name":"UNIX Symbolic Link (Symlink) Following"}],"description":"aiohttp is an asynchronous HTTP client/server framework for asyncio and Python. In versions on the 3.10 branch prior to version 3.10.2, static routes which contain files with compressed variants (`.gz` or `.br` extension) are vulnerable to path traversal outside the root directory if those variants are symbolic links. The server protects static routes from path traversal outside the root directory when `follow_symlinks=False` (default).  It does this by resolving the requested URL to an absolute path and then checking that path relative to the root. However, these checks are not performed when looking for compressed variants in the `FileResponse` class, and symbolic links are then automatically followed when performing the `Path.stat()` and `Path.open()` to send the file. Version 3.10.2 contains a patch for the issue.","ecosystems":["PyPI","SUSE:Linux Enterprise Module for Public Cloud 15 SP4","SUSE:Linux Enterprise Module for Python 3 15 SP5","SUSE:Linux Enterprise
