{"answers":{"affected":"4 open source packages ship an affected version, including com.manydesigns:portofino-core and com.manydesigns:portofino-dispatcher. It affects 1 product.","exploited":"There is no known exploitation of CVE-2021-29451 in the wild and no public exploit code.","fix":"Upgrade com.manydesigns:portofino-core to 5.2.1 or later.","what":"CVE-2021-29451 is a critical vulnerability in ManyDesigns Portofino, published on 16 Apr 2021."},"fix_prompt":"Check this codebase for CVE-2021-29451 and fix it if it is affected.\n\nWhat it is: CVE-2021-29451 is a critical vulnerability in ManyDesigns Portofino, published on 16 Apr 2021. \nExploitation: There is no known exploitation of CVE-2021-29451 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- com.manydesigns:portofino-core (Maven): affected from 5.0.0; fixed in 5.2.1\n- com.manydesigns:portofino-core (Maven): affected from 5.0.0; fixed in 5.2.1\n- com.manydesigns:portofino-dispatcher (Maven): affected from 5.0.0; fixed in 5.2.1\n- com.manydesigns:portofino-dispatcher (Maven): affected from 5.0.0; fixed in 5.2.1\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-2021-29451/ (Markdown: https://insights.sbomify.com/CVE-2021-29451/index.md)","id":"CVE-2021-29451","markdown":"https://insights.sbomify.com/CVE-2021-29451/index.md","name":"CVE-2021-29451","record":{"aliases":["GHSA-6g3c-2mh5-7q6x"],"analysis":null,"analysis_generated_by":null,"assigner":"GitHub_M","cpe":[{"product":"portofino","vendor":"manydesigns"}],"cvss":{"score":9.1,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-347","name":"Improper Verification of Cryptographic Signature"}],"description":"Portofino is an open source web development framework.
