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-2026-54276 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- aiohttp (PyPI): affected all versions; fixed in 3.14.1\n- aiohttp (PyPI): affected all versions; fixed in 3.14.1\n- aiohttp (PyPI): affected all versions; fixed in 3.14.1\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-2026-54276/ (Markdown: https://insights.sbomify.com/CVE-2026-54276/index.md)","id":"CVE-2026-54276","markdown":"https://insights.sbomify.com/CVE-2026-54276/index.md","name":"CVE-2026-54276","record":{"aliases":["CLEANSTART-2026-LF30354","CLEANSTART-2026-WD11745","DEBIAN-CVE-2026-54276","ECHO-063c-9c61-c3d6","GHSA-hpj7-wq8m-9hgp","MINI-5249-7v73-j4m3","MINI-6xm5-3fv8-rqj7","MINI-74j9-wxm5-8x4w","MINI-7jg4-cv7c-fhjh","MINI-92hf-cx59-r652","MINI-9p86-9m9f-5j95","MINI-cpjj-j3xj-5ch8","MINI-g6q8-wv28-r9h4","MINI-gcp3-wmx5-6qff","MINI-ghqf-5fwg-f275","MINI-j7cw-pp2m-f5gj","MINI-j7qr-2w2h-m5m9","MINI-pfvf-9qq6-c35m","MINI-q974-h3q4-2qfv","MINI-r54q-297h-3jjg","MINI-rqqr-844g-hxgp","MINI-xcgw-xh5f-xp46","PYSEC-2026-2109","ROOT-APP-PYPI-CVE-2026-54276","UBUNTU-CVE-2026-54276"],"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":"AIOHTTP's DigestAuthMiddleware may leak user credentials to cross-origin redirect targets, allowing attackers to potentially recover sensitive authentication data.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"aiohttp","vendor":"aiohttp"}],"cvss":{"score":6.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-601","name":"URL Redirection to Untrusted Site"},{"id":"CWE-522","name":"Insufficiently Protected Credentials"},{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to 3.14.1, DigestAuthMiddleware can send an authentication response after following a cross-origin redirect. This likely requires an open redirect vulnerability or similar on the target domain for an attacker to be able to execute. Further, the attacker is only receiving the digest, so should only be able to extract the user's credentials if the cryptography is weak or there is some kind of password reuse.
