It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of GHSA-3g4q-2f67-2gvh in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/tinfoil-factory/netfoil (Go): affected all versions; fixed in 0.3.0\n- github.com/tinfoil-factory/netfoil (Go): affected all versions; fixed in 0.3.0\n- github.com/tinfoil-factory/netfoil (Go): affected all versions; fixed in 0.3.0\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-3g4q-2f67-2gvh/ (Markdown: https://insights.sbomify.com/GHSA-3g4q-2f67-2gvh/index.md)","id":"GHSA-3g4q-2f67-2gvh","markdown":"https://insights.sbomify.com/GHSA-3g4q-2f67-2gvh/index.md","name":"GHSA-3g4q-2f67-2gvh","record":{"aliases":["GO-2026-5933"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Go LRU cache library","requires_auth":"none","summary":"A local attacker can exhaust memory in the netfoil LRU cache, causing service restarts due to resource leaks.","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":"### Summary\nWhen an entry was removed from the LRU cache, a pointer to the removed element was not properly cleaned up.\n\n### Impact\nA local attacker can get netfoil to use more memory.
