An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of GHSA-f8qm-hmm3-fv7f in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- namada-apps (crates.io): affected from 1.0.0; fixed in 1.1.0\n- namada-apps (crates.io): affected from 1.0.0; fixed in 1.1.0\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/GHSA-f8qm-hmm3-fv7f/ (Markdown: https://insights.sbomify.com/GHSA-f8qm-hmm3-fv7f/index.md)","id":"GHSA-f8qm-hmm3-fv7f","markdown":"https://insights.sbomify.com/GHSA-f8qm-hmm3-fv7f/index.md","name":"GHSA-f8qm-hmm3-fv7f","record":{"aliases":[],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Namada blockchain node","requires_auth":"none","summary":"A malicious transaction can cause excessive computation in mempool validation, slowing down nodes and causing denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"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\nA malicious transaction may cause an expensive computation in mempool validation.\n\nA transaction with multiple repeated sections causes the section hash calculation used for signature validation to grow exponentially (and potentially even cubic) in proportion to number of sections.
