What is CVE-2025-14762?

The AWS SDK for Ruby, an open-source client-side encryption library, exhibits a vulnerability where a missing cryptographic key commitment could allow a user with write access to an S3 bucket to create a new Encrypted Data Key (EDK). This EDK could potentially decrypt to different plaintext when stored in an 'instruction file', rather than in S3's metadata record. Users are strongly advised to upgrade to version 1.208.0 or later to address this security concern.
