Summary
Failure to verify the public key of a SignedEnvelope against the PeerId in a PeerRecord
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.
Any combination was considered valid.
This allows an attacker to republish an existing PeerRecord with a different PeerId.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Frequently Asked Questions
- What is GHSA-WC36-XGCC-JWPR? GHSA-WC36-XGCC-JWPR is a high-severity security vulnerability in libp2p-core (rust), affecting versions >= 0.30.0-rc.1, < 0.30.2. It is fixed in 0.30.2.
- Which versions of libp2p-core are affected by GHSA-WC36-XGCC-JWPR? libp2p-core (rust) versions >= 0.30.0-rc.1, < 0.30.2 is affected.
- Is there a fix for GHSA-WC36-XGCC-JWPR? Yes. GHSA-WC36-XGCC-JWPR is fixed in 0.30.2. Upgrade to this version or later.
- Is GHSA-WC36-XGCC-JWPR exploitable, and should I be worried? Whether GHSA-WC36-XGCC-JWPR is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether GHSA-WC36-XGCC-JWPR is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
