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-2026-108525/ (Markdown: https://insights.sbomify.com/CVE-2026-108525/index.md)","id":"CVE-2026-108525","markdown":"https://insights.sbomify.com/CVE-2026-108525/index.md","name":"CVE-2026-108525","record":{"aliases":["EEF-CVE-2026-108525","GHSA-c3g7-2pg5-qvwh","UBUNTU-CVE-2026-108525"],"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 implementation of mtrudel bandit allows an unauthenticated remote attacker to exhaust server memory via DATA frames sent past the advertised receive window. The attacker requests a response larger than the 65,535-byte initial window and withholds WINDOW_UPDATE, so the stream process blocks while sending and stops reading, then floods small DATA frames on that stream. Every frame is queued in the stream's mailbox until the BEAM node runs out of memory.\n\nBandit.HTTP2.Connection.handle_frame/3 in lib/bandit/http2/connection.ex forwards each DATA frame to the stream process without consulting the receive window, and Bandit.HTTP2.FlowControl.compute_recv_window/2 replenishes the window as data arrives rather than as it is consumed, and never answers a violation with FLOW_CONTROL_ERROR.\n\nThis issue affects bandit: from 0.3.1 before 1.14.0.","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 inbound flow control is not enforced, letting a client queue unbounded DATA in stream processes in Bandit","id":"CVE-2026-108525","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Hex","product":null,"products":[],"type":null,"year":"2026"},"n_packages":1,"n_references":5,"next":{"headline":"SETTINGS and stream-0 WINDOW_UPDATE frames trigger quadratic work over blocked streams in Bandit","id":"CVE-2026-108529"},"packages":[{"ecosystem":"Hex","fixed":["1.14.0"],"introduced":["0.3.1"],"last_affected":[],"package":"bandit","purl":"pkg:hex/bandit","source":"EEF-CVE-2026-108525"}],"prev":{"headline":"Studio-Saelix Sencho git-sources Browse API Endpoint outboundTarget.ts server-side request forgery","id":"CVE-2026-108523"},"products":["bandit"],"published":"2026-10-26","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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-10-26","vendors":["mtrudel"]},"summary":null,"url":"https://insights.sbomify.com/CVE-2026-108525/"}
