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-2026-54490 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- websocket-driver (npm): affected all versions; fixed in 0.7.5\n- websocket-driver (npm): affected all versions; fixed in 0.7.5\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-2026-54490/ (Markdown: https://insights.sbomify.com/CVE-2026-54490/index.md)","id":"CVE-2026-54490","markdown":"https://insights.sbomify.com/CVE-2026-54490/index.md","name":"CVE-2026-54490","record":{"aliases":["CLEANSTART-2026-EE87307","CLEANSTART-2026-WO79894","DEBIAN-CVE-2026-54490","GHSA-mp7j-qc5w-4988","MINI-crfg-gm76-qccg","MINI-cw4c-773j-f335","MINI-h82g-hq6c-9vvr","MINI-q2rx-rjxq-mvxq","MINI-rg82-2w23-f2jg","MINI-xxmq-8chh-f68j","UBUNTU-CVE-2026-54490"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"Node.js WebSocket library","requires_auth":"none","summary":"Attackers can bypass message size limits in websocket-driver when using permessage-deflate, causing resource exhaustion and denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":6.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:L","version":"4.0"},"cwes":[{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"}],"description":"websocket-driver is a WebSocket protocol handler with pluggable I/O. Prior to 0.7.5, if this library is used with the permessage-deflate extension, a WebSocket server or client can be made to accept messages that are larger than the configured maximum message size because the limit is checked against the message frames' length headers, which give the size of the compressed data, not the size after decompression in lib/websocket/driver/hybi.js. This can lead to applications accepting larger messages than expected and exceeding their intended resource usage.
