Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-33729 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/openfga/openfga (Go): affected all versions; fixed in 1.13.1\n- github.com/openfga/openfga (Go): affected all versions; fixed in 1.13.1\n- github.com/openfga/openfga (Go): affected all versions; fixed in 1.13.1\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/CVE-2026-33729/ (Markdown: https://insights.sbomify.com/CVE-2026-33729/index.md)","id":"CVE-2026-33729","markdown":"https://insights.sbomify.com/CVE-2026-33729/index.md","name":"CVE-2026-33729","record":{"aliases":["GHSA-h6c8-cww8-35hf","GO-2026-4857","MINI-2p27-m3mg-6hvq","MINI-2vmx-x97v-52c4","MINI-6mp2-jr44-r353","MINI-6x6q-7874-7fph","MINI-76c9-3fwh-w37g","MINI-8659-hx2h-cvp8","MINI-8mx5-599r-j5v4","MINI-9v4f-8hx3-c8gm","MINI-ffm9-whjr-937v","MINI-h6qq-v6fr-5539","MINI-hghj-gxrc-8mrx","MINI-mq59-pcx6-94m7","MINI-mxq3-827h-8pmh","MINI-p2jr-cj4m-mh55","MINI-p4x8-38j4-vj75","MINI-r34w-cwp2-r223","MINI-wf3r-fjhw-3637","MINI-wvjf-r74w-9hq2"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"OpenFGA authorization engine","requires_auth":"low_privilege","summary":"Attackers can bypass authorization checks in OpenFGA when caching is enabled and specific model conditions are used, leading to unauthorized access.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"openfga","vendor":"openfga"}],"cvss":{"score":5.8,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:N/VI:N/VA:N/SC:H/SI:H/SA:H","version":"4.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"},{"id":"CWE-345","name":"Insufficient Verification of Data Authenticity"},{"id":"CWE-1289","name":"Improper Validation of Unsafe Equivalence in Input"}],"description":"OpenFGA is a high-performance and flexible authorization/permission engine built for developers and inspired by Google Zanzibar.
