An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-54072 exists.\n\nAffected packages and fixed versions:\n- github.com/authorizerdev/authorizer (Go): affected all versions; fixed in 0.0.0-20260409051328-bd3f5baf6d3d\n- github.com/authorizerdev/authorizer (Go): affected all versions; fixed in 0.0.0-20260409051328-bd3f5baf6d3d\n- github.com/authorizerdev/authorizer (Go): affected all versions; fixed in 0.0.0-20260409051328-bd3f5baf6d3d\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-2026-54072/ (Markdown: https://insights.sbomify.com/CVE-2026-54072/index.md)","id":"CVE-2026-54072","markdown":"https://insights.sbomify.com/CVE-2026-54072/index.md","name":"CVE-2026-54072","record":{"aliases":["GHSA-h29v-hj44-q8cv","GO-2026-5959"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"OAuth2 authorization server","requires_auth":"none","summary":"An unauthenticated attacker can leak OAuth2 tokens by exploiting an unvalidated redirect_uri in the /authorize endpoint of Authorizer.","user_interaction":"required","vuln_class":"open_redirect"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":9.3,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-601","name":"URL Redirection to Untrusted Site"}],"description":"Authorizer is an open-source, self-hostable authentication and authorization server. Prior to version 2.2.1, the `/authorize` endpoint accepts any `redirect_uri` without validating it against `AllowedOrigins`. When `response_type=token` or `response_type=id_token`, the server appends `access_token`, `id_token`, and `refresh_token` as query parameters and issues a 302 redirect to the attacker-supplied URL. An unauthenticated attacker can obtain the required `client_id` from the public `/graphql?query={meta{client_id}}` endpoint. A partial fix was applied in v2.0.1 to other handlers (`oauth_login`, `verify_email`, `magic_link_login`, `forgot_password`, `invite_members`, `oauth_callback`) but `/authorize` was not included. Version 2.2.1 contains a more complete fix.","ecosystems":["Go"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"Authorizer: Unvalidated redirect_uri in /authorize leaks OAuth2 tokens to attacker-controlled URL","id":"CVE-2026-54072","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"open_redirect","year":"2026"},"n_packages":3,"n_references":1,"next":{"headline":"VeraCrypt: Hidden volume quick format weakens plausible deniability","id":"CVE-2026-54073"},"packages":[{"ecosystem":"Go","fixed":["0.0.0-20260409051328-bd3f5baf6d3d"],"introduced":["0"],"last_affected":[],"package":"github.com/authorizerdev/authorizer","purl":null,"source":"GHSA-h29v-hj44-q8cv"},{"ecosystem":"Go","fixed":["0.0.0-20260409051328-bd3f5baf6d3d"],"introduced":["0"],"last_affected":[],"package":"github.com/authorizerdev/authorizer","purl":"pkg:golang/github.com/authorizerdev/authorizer","source":"GHSA-h29v-hj44-q8cv"},{"ecosystem":"Go","fixed":["0.0.0-20260409051328-bd3f5baf6d3d"],"introduced":["0"],"last_affected":[],"package":"github.com/authorizerdev/authorizer","purl":"pkg:golang/github.com/authorizerdev/authorizer","source":"GO-2026-5959"}],"prev":{"headline":"BabelDOC: Arbitrary Code Execution via CMap Pickle Deserialization in babeldoc/pdfminer/cmapdb.py","id":"CVE-2026-54071"},"products":["authorizer"],"published":"2026-09-11","related":[],"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":"CC BY 4.0","name":"Go Vulnerability Database","prefix":"GO"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-09-15","vendors":["authorizerdev"]},"summary":"An unauthenticated attacker can leak OAuth2 tokens by exploiting an unvalidated redirect_uri in the /authorize endpoint of Authorizer.","url":"https://insights.sbomify.com/CVE-2026-54072/"}
