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-2023-33199 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/sigstore/rekor (Go): affected all versions; fixed in 1.2.0\n- github.com/sigstore/rekor (Go): affected all versions; fixed in 1.2.0\n- github.com/sigstore/rekor (Go): affected all versions; fixed in 1.2.0\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-2023-33199/ (Markdown: https://insights.sbomify.com/CVE-2023-33199/index.md)","id":"CVE-2023-33199","markdown":"https://insights.sbomify.com/CVE-2023-33199/index.md","name":"CVE-2023-33199","record":{"aliases":["GHSA-frqx-jfcm-6jjr","GO-2023-1795","SUSE-SU-2023:2515-1","openSUSE-SU-2024:12965-1"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Rekor supply chain ledger","requires_auth":"none","summary":"Malformed intoto entries cause a panic in Rekor, resulting in a 500 error and minimal availability impact for supply chain metadata services.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"rekor","vendor":"linuxfoundation"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-617","name":"Reachable Assertion"}],"description":"Rekor's goals are to provide an immutable tamper resistant ledger of metadata generated within a software projects supply chain. A malformed proposed entry of the `intoto/v0.0.2` type can cause a panic on a thread within the Rekor process. The thread is recovered so the client receives a 500 error message and service still continues, so the availability impact of this is minimal. This has been fixed in v1.2.0 of Rekor. Users are advised to upgrade.
