Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The dcap-qvl library, published as crates.io dcap-qvl and PyPI dcap-qvl before 0.3.9 and as npm @phala/dcap-qvl before 0.3.9, does not verify the signature of QE Identity collateral fetched from the PCCS or enforce policy checks on the QE Report. An attacker able to supply forged QE Identity data could whitelist a malicious Quoting Enclave and get untrusted quotes accepted as valid, bypassing remote attestation. Upgrade to 0.3.9. The npm packages @phala/dcap-qvl-node and @phala/dcap-qvl-web have no fixed version listed; the source advises switching to @phala/dcap-qvl.
