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-wc36-xgcc-jwpr in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- libp2p-core (crates.io): affected from 0.30.0-rc.1; fixed in 0.30.2, 0.31.1\n- libp2p-core (crates.io): affected from 0.30.0-rc.1; fixed in 0.30.2\n- libp2p-core (crates.io): affected from 0.30.0-rc.1; fixed in 0.30.2\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-wc36-xgcc-jwpr/ (Markdown: https://insights.sbomify.com/GHSA-wc36-xgcc-jwpr/index.md)","id":"GHSA-wc36-xgcc-jwpr","markdown":"https://insights.sbomify.com/GHSA-wc36-xgcc-jwpr/index.md","name":"GHSA-wc36-xgcc-jwpr","record":{"aliases":["RUSTSEC-2022-0009"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Rust libp2p crate","requires_auth":"none","summary":"Attackers can spoof peer identities by republishing records with mismatched keys, bypassing identity verification in libp2p networks.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"Affected versions of this crate did not check that the public key the signature was created with matches the peer ID of the peer record. \nAny combination was considered valid.\n\nThis allows an attacker to republish an existing `PeerRecord` with a different `PeerId`.","ecosystems":["crates.io"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":true,"headline":"Failure to verify the public key of a `SignedEnvelope` against the `PeerId` in a `PeerRecord`","id":"GHSA-wc36-xgcc-jwpr","indexable":true,"kev":null,"kind":"advisory","links":{"ecosystem":"crates.io","product":null,"products":[],"type":"security_feature_bypass","year":"2022"},"n_packages":3,"n_references":null,"packages":[{"ecosystem":"crates.io","fixed":["0.30.2","0.31.1"],"introduced":["0.30.0-rc.1","0.31.0-0"],"last_affected":[],"package":"libp2p-core","purl":"pkg:cargo/libp2p-core","source":"RUSTSEC-2022-0009"},{"ecosystem":"crates.io","fixed":["0.30.2"],"introduced":["0.30.0-rc.1"],"last_affected":[],"package":"libp2p-core","purl":null,"source":"GHSA-wc36-xgcc-jwpr"},{"ecosystem":"crates.io","fixed":["0.30.2"],"introduced":["0.30.0-rc.1"],"last_affected":[],"package":"libp2p-core","purl":"pkg:cargo/libp2p-core","source":"GHSA-wc36-xgcc-jwpr"}],"products":null,"published":"2022-02-07","related":[],"sources":[{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"open","licence":"CC0 1.0","name":"RustSec","prefix":"RUSTSEC"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":"Attackers can spoof peer identities by republishing records with mismatched keys, bypassing identity verification in libp2p networks.","url":"https://insights.sbomify.com/GHSA-wc36-xgcc-jwpr/"}
