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-2026-29792 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- @feathersjs/authentication-oauth (npm): affected from 5.0.0; fixed in 5.0.42\n- @feathersjs/authentication-oauth (npm): affected from 5.0.0; fixed in 5.0.42\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-2026-29792/ (Markdown: https://insights.sbomify.com/CVE-2026-29792/index.md)","id":"CVE-2026-29792","markdown":"https://insights.sbomify.com/CVE-2026-29792/index.md","name":"CVE-2026-29792","record":{"aliases":["GHSA-wg9x-qfgw-pxhj"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"FeathersJS OAuth library","requires_auth":"none","summary":"An unauthenticated attacker can forge OAuth callback requests to bypass authentication and obtain valid access tokens for existing users.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"feathers","vendor":"feathersjs"}],"cvss":{"score":9.3,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"Feathersjs is a framework for creating web APIs and real-time applications with TypeScript or JavaScript. From 5.0.0 to before 5.0.42, an unauthenticated attacker can send a crafted GET request directly to /oauth/:provider/callback with a forged profile in the query string. The OAuth service's authentication payload has a fallback chain that reaches params.query (the raw request query) when Grant's session/state responses are empty. Since the attacker never initiated an OAuth authorize flow, Grant has no session to work with and produces no response, so the fallback fires. The forged profile then drives entity lookup and JWT minting. The attacker gets a valid access token for an existing user without ever contacting the OAuth provider. This vulnerability is fixed in 5.0.42.","ecosystems":["npm"],"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":"Feathersjs has an OAuth Callback Account Takeover","id":"CVE-2026-29792","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"auth_bypass","year":"2026"},"n_packages":2,"n_references":1,"next":{"headline":"NoSQL Injection via WebSocket id Parameter in MongoDB Adapter","id":"CVE-2026-29793"},"packages":[{"ecosystem":"npm","fixed":["5.0.42"],"introduced":["5.0.0"],"last_affected":[],"package":"@feathersjs/authentication-oauth","purl":null,"source":"GHSA-wg9x-qfgw-pxhj"},{"ecosystem":"npm","fixed":["5.0.42"],"introduced":["5.0.0"],"last_affected":[],"package":"@feathersjs/authentication-oauth","purl":"pkg:npm/%40feathersjs/authentication-oauth","source":"GHSA-wg9x-qfgw-pxhj"}],"prev":{"headline":"Agentgateway: Missing parameter sanitization in MCP to OpenAPI conversion","id":"CVE-2026-29791"},"products":["authentication-oauth","feathers"],"published":"2026-03-10","related":[{"cvss_score":9.3,"headline":"NoSQL Injection via WebSocket id Parameter in MongoDB Adapter","id":"CVE-2026-29793","kev_date_added":null,"published":"2026-03-10"},{"cvss_score":8.2,"headline":"Feathers exposes internal headers via unencrypted session cookie","id":"CVE-2026-27193","kev_date_added":null,"published":"2026-02-21"},{"cvss_score":7.6,"headline":"Feathers has an origin validation bypass via prefix matching","id":"CVE-2026-27192","kev_date_added":null,"published":"2026-02-21"},{"cvss_score":7.5,"headline":"feathersjs socket handler allows abusing implicit toString","id":"CVE-2023-37899","kev_date_added":null,"published":"2023-07-19"},{"cvss_score":7.4,"headline":"Feathers: Open Redirect in OAuth callback enables account takeover","id":"CVE-2026-27191","kev_date_added":null,"published":"2026-02-21"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"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":"total"},"state":"PUBLISHED","updated":"2026-03-11","vendors":["@feathersjs","feathersjs"]},"summary":"An unauthenticated attacker can forge OAuth callback requests to bypass authentication and obtain valid access tokens for existing users.","url":"https://insights.sbomify.com/CVE-2026-29792/"}
