CVE-2024-21669

28
FAUCET Score

CVE-2024-21669 affects Hyperledger Aries Cloud Agent Python (ACA-Py) versions 0.7.0 through 0.10.4, allowing attackers to bypass verification of W3C Verifiable Credentials with Linked Data Proofs. The vulnerability stems from the presentation document's proof not being factored into the final verification result, enabling the presentation of invalid proofs and replay attacks by malicious verifiers. With a CVSS score of 8.8 (High), this flaw presents a significant risk due to its network attack vector and low attack complexity, potentially leading to high impact on confidentiality, integrity, and availability. While there is no evidence of active exploitation, public exploit code, or inclusion in the CISA KEV catalog, the vulnerability has garnered considerable community discussion, indicating awareness and potential for future exploitation.
