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-2026-116078/ (Markdown: https://insights.sbomify.com/CVE-2026-116078/index.md)","id":"CVE-2026-116078","markdown":"https://insights.sbomify.com/CVE-2026-116078/index.md","name":"CVE-2026-116078","record":{"aliases":["EEF-CVE-2026-116078","GHSA-pxjf-g536-7r93","UBUNTU-CVE-2026-116078"],"analysis":null,"analysis_generated_by":null,"assigner":"EEF","cpe":[],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"}],"description":"Allocation of Resources Without Limits or Throttling vulnerability in the HTTP/2 request body reader of mtrudel bandit allows an unauthenticated remote attacker to exhaust server memory via a request body sent as many 1-byte DATA frames.\n\ndo_read_data/5 in lib/bandit/http2/stream.ex keeps every DATA frame payload as its own list element until the read returns. The :length option of read_body/2 counts body bytes, not frames, so a body of 1-byte frames costs a list cell and a binary term per byte. Interleaving the frames across up to 500 concurrent streams per connection keeps each stream consuming its frames as they arrive; in the reporter's test, 100 streams held 25 to 40 MiB of stream process memory for 5 MB sent. Only routes whose Plug reads the request body are affected, which includes any route behind Plug.Parsers.\n\nThis issue affects bandit: from 0.3.1 before 1.14.1.","ecosystems":["Hex"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"HTTP/2 request bodies made of 1-byte DATA frames amplify memory use in Bandit","id":"CVE-2026-116078","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Hex","product":null,"products":[],"type":null,"year":"2026"},"n_packages":1,"n_references":5,"next":{"headline":"EyouCMS function.php remote_file_to_local server-side request forgery","id":"CVE-2026-116094"},"packages":[{"ecosystem":"Hex","fixed":["1.14.1"],"introduced":["0.3.1"],"last_affected":[],"package":"bandit","purl":"pkg:hex/bandit","source":"EEF-CVE-2026-116078"}],"prev":{"headline":"Leon before commit 50df142 Path Traversal via /download model Command","id":"CVE-2026-116073"},"products":["bandit"],"published":"2026-10-28","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"Erlang Ecosystem Foundation","prefix":"EEF"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-10-28","vendors":["mtrudel"]},"summary":null,"url":"https://insights.sbomify.com/CVE-2026-116078/"}
