Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of GHSA-f28g-86hc-823q in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/superfly/tokenizer (Go): affected all versions; fixed in 0.0.1\n- github.com/superfly/tokenizer (Go): affected all versions; fixed in 0.0.1\n- github.com/superfly/tokenizer (Go): affected all versions; fixed in 0.0.1\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/GHSA-f28g-86hc-823q/ (Markdown: https://insights.sbomify.com/GHSA-f28g-86hc-823q/index.md)","id":"GHSA-f28g-86hc-823q","markdown":"https://insights.sbomify.com/GHSA-f28g-86hc-823q/index.md","name":"GHSA-f28g-86hc-823q","record":{"aliases":["GO-2023-1914"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Go Tokenizer library","requires_auth":"low_privilege","summary":"Authorized clients can brute-force token secrets via the Proxy-Tokenizer header, potentially bypassing security controls.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"### Impact\n\nAuthorized clients, having an `inject_processor` secret, could brute-force the secret token value by abusing the `fmt` parameter to the `Proxy-Tokenizer` header.\n\n### Patches\n\nThis was fixed in https://github.com/superfly/tokenizer/pull/8 and further mitigated in https://github.com/superfly/tokenizer/pull/9.","ecosystems":["Go"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":true,"headline":"Tokenizer vulnerable to client brute-force of token secrets","id":"GHSA-f28g-86hc-823q","indexable":true,"kev":null,"kind":"advisory","links":{"ecosystem":"Go","product":null,"products":[],"type":"information_disclosure","year":"2023"},"n_packages":3,"n_references":null,"packages":[{"ecosystem":"Go","fixed":["0.0.1"],"introduced":["0"],"last_affected":[],"package":"github.com/superfly/tokenizer","purl":null,"source":"GHSA-f28g-86hc-823q"},{"ecosystem":"Go","fixed":["0.0.1"],"introduced":["0"],"last_affected":[],"package":"github.com/superfly/tokenizer","purl":"pkg:golang/github.com/superfly/tokenizer","source":"GHSA-f28g-86hc-823q"},{"ecosystem":"Go","fixed":["0.0.1"],"introduced":["0"],"last_affected":[],"package":"github.com/superfly/tokenizer","purl":"pkg:golang/github.com/superfly/tokenizer","source":"GO-2023-1914"}],"products":null,"published":"2023-07-13","related":[],"sources":[{"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"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":"Authorized clients can brute-force token secrets via the Proxy-Tokenizer header, potentially bypassing security controls.","url":"https://insights.sbomify.com/GHSA-f28g-86hc-823q/"}
