An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-33637 exists.\n\nAffected packages and fixed versions:\n- faraday (RubyGems): affected from 2.0.0; fixed in 2.14.2\n- faraday (RubyGems): affected from 2.0.0; fixed in 2.14.2\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-2026-33637/ (Markdown: https://insights.sbomify.com/CVE-2026-33637/index.md)","id":"CVE-2026-33637","markdown":"https://insights.sbomify.com/CVE-2026-33637/index.md","name":"CVE-2026-33637","record":{"aliases":["CLEANSTART-2026-LW94044","CLEANSTART-2026-TE06147","DEBIAN-CVE-2026-33637","GHSA-5rv5-xj5j-3484","MINI-5rfv-cmg2-qqxc","MINI-5vwc-99wm-6fpm","MINI-6qcm-cv6h-mg62","MINI-888x-xgfv-87qw","MINI-8r98-pc9q-7778","MINI-chj3-pr2c-pgx9","MINI-f6wv-m28r-r656","MINI-fc5h-2wgf-ffjv","MINI-fh36-8rhr-hpq3","MINI-fqhw-844c-pg78","MINI-fxpr-h987-ph23","MINI-gq9f-pc55-w8rc","MINI-hm4w-xc33-3qf2","MINI-hmj4-3623-wmqq","MINI-hw3v-jx5f-37pf","MINI-jfg2-xp43-8w8j","MINI-mv48-xj37-c3mp","MINI-mxvf-5895-pv33","MINI-q7xq-m73x-wwh8","MINI-q8fv-jhp2-x356","MINI-rc2h-q8cm-439h","MINI-rqww-rp75-4h6h","MINI-vmg2-3g7g-pgrf","MINI-w2h3-6rvf-74q5","MINI-xqhg-25j9-2x29","UBUNTU-CVE-2026-33637"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Ruby HTTP client library","requires_auth":"none","summary":"Attackers can bypass host scoping in Faraday HTTP client to redirect requests to malicious hosts, leaking sensitive headers and parameters.","user_interaction":"not_required","vuln_class":"ssrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"faraday","vendor":"faraday_project"}],"cvss":{"score":0,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-918","name":"Server-Side Request Forgery"}],"description":"Faraday is an HTTP client library abstraction layer that provides a common interface over many adapters.

This bypasses the February 2026 fix for GHSA-33mh-2634-fwr2 and enables off-host request forgery: a request built from a fixed-base Faraday::Connection can be redirected to an attacker-controlled host, forwarding connection-scoped values such as Authorization headers and default query parameters.
