CVE-2025-14761 is a medium-severity vulnerability in the AWS SDK for PHP involving the use of a broken or risky cryptographic algorithm. The issue arises from a missing cryptographic key commitment when encrypted data keys (EDKs) are stored in an instruction file rather than S3 metadata. This flaw allows a user with write access to an S3 bucket to introduce a malicious EDK that decrypts to different plaintext, potentially compromising data integrity. The vulnerability does not impact confidentiality or availability directly and requires low privileges but high attack complexity. No known exploits are currently reported in the wild. AWS has addressed this vulnerability in SDK version 3.368.0 and later. European organizations using AWS SDK for PHP with S3 encryption should prioritize upgrading to mitigate risks. Countries with significant AWS adoption and critical cloud infrastructure are more likely to be affected.
