A `ProtoNode` may be modified in such a way as to cause various encode errors which will trigger a panic on common method calls that don't allow for error returns. A `ProtoNode` should only be able to encode to valid DAG-PB, attempting to encode invalid DAG-PB forms will result in an error from the codec. Manipulation of an existing (newly created or decoded) `ProtoNode` using the modifier methods did not account for certain states that would place the `ProtoNode` into an unencodeable form. Due to conformance with the [`github.com/ipfs/go-block-format#Block`](https://pkg.go.dev/github.com/ipfs/go-block-format#Block) and [`github.com/ipfs/go-ipld-format#Node`](https://pkg.go.dev/github.com/ipfs/go-ipld-format#Node) interfaces, certain methods, which internally require a re-encode if state has changed, will panic due to the inability to return an error. This issue has been addressed across a number of pull requests. Users are advised to upgrade to version 0.8.1 for a complete set of fixes. Users unable to upgrade may attempt to mitigate this issue by sanitising inputs when allowing user-input to set a new `CidBuilder` on a `ProtoNode` and by sanitising `Tsize` (`Link#Size`) values such that they are a reasonable byte-size for sub-DAGs where derived from user-input.\n"}],"source":{"advisory":"GHSA-x39j-h85h-3f46","discovery":"UNKNOWN"}},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-03T03:43:46.142Z"},"title":"CVE Program Container","references":[{"name":"https://github.com/ipfs/go-merkledag/security/advisories/GHSA-x39j-h85h-3f46","tags":["x_refsource_CONFIRM","x_transferred"],"url":"https://github.com/ipfs/go-merkledag/security/advisories/GHSA-x39j-h85h-3f46"},{"name":"https://github.com/ipfs/go-merkledag/issues/90","tags":["x_refsource_MISC","x_transferred"],"url":"https://github.com/ipfs/go-merkledag/issues/90"},{"name":"https://github.com/ipfs/kubo/issues/9297","tags":["x_refsource_MISC","x_transferred"],"url":"https://github.com/ipfs/kubo/issues/9297"},{"name":"https://github.com/ipfs/go-merkledag/pull/91","tags":["x_refsource_MISC","x_transferred"],"url":"https://github.com/ipfs/go-merkledag/pull/91"},{"name":"https://github.com/ipfs/go-merkledag/pull/92","tags":["x_refsource_MISC","x_transferred"],"url":"https://github.com/ipfs/go-merkledag/pull/92"},{"name":"https://github.com/ipfs/go-merkledag/pull/93","tags":["x_refsource_MISC","x_transferred"],"url":"https://github.com/ipfs/go-merkledag/pull/93"},{"name":"https://en.wikipedia.org/wiki/Directed_acyclic_graph","tags":["x_refsource_MISC","x_transferred"],"url":"https://en.wikipedia.org/wiki/Directed_acyclic_graph"},{"name":"https://github.com/ipfs/go-merkledag/releases/tag/v0.8.0","tags":["x_refsource_MISC","x_transferred"],"url":"https://github.com/ipfs/go-merkledag/releases/tag/v0.8.0"},{"name":"https://github.com/ipfs/go-merkledag/releases/tag/v0.8.1","tags":["x_refsource_MISC","x_transferred"],"url":"https://github.com/ipfs/go-merkledag/releases/tag/v0.8.1"}]},{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2025-04-23T15:48:01.494241Z","id":"CVE-2022-23495","options":[{"Exploitation":"none"},{"Automatable":"yes"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2025-04-23T16:31:04.725Z"}}]}}
