  "summary" : "Credential disclosure in syft when SYFT_ATTEST_PASSWORD environment variable set",
  "details" : "A password disclosure flaw was found in Syft versions v0.69.0 and v0.69.1. This flaw leaks the password stored in the SYFT_ATTEST_PASSWORD environment variable.\n\n### Impact\nThe `SYFT_ATTEST_PASSWORD` environment variable is for the `syft attest` command to generate attested SBOMs for the given container image. This environment variable is used to decrypt the private key (provided with `syft attest --key <path-to-key-file>`)  during the signing process while generating an SBOM attestation. \n\nThis vulnerability affects users running syft that have the `SYFT_ATTEST_PASSWORD` environment variable set with credentials (regardless of if the attest command is being used or not). Users that do not have the environment variable `SYFT_ATTEST_PASSWORD` set are not affected by this issue.\n\nThe credentials are leaked in two ways:\n- in the syft logs when `-vv` or `-vvv` are used in the syft command (which is any log level >= `DEBUG`)\n- in the attestation or SBOM only when the `syft-json` format is used \n\nNote that as of v0.69.0 any generated attestations by the `syft attest` command are uploaded to the OCI registry (if you have write access to that registry) in the same way `cosign attach` is done. This means that any attestations generated for the affected versions of syft when the `SYFT_ATTEST_PASSWORD` environment variable was set would leak credentials in the attestation payload uploaded to the OCI registry.\n\nExample commands run from affected versions of syft that show the credential disclosure:\n```bash\n$ SYFT_ATTEST_PASSWORD=123456 syft <container-image-or-directory-input> -o syft-json | grep 123456\n# \"123456\" is in the output\n\n$ SYFT_ATTEST_PASSWORD=123456 syft attest <container-image-input> -o syft-json \n$ cosign download attestation <container-image-input> | jq -r '.payload' | base64 -d | grep 123456\n# \"123456\" is in the output\n```\n\n### Patches\n\nThe patch has been released in v0.70.0.\n\n### Workarounds\n\nThere are no workarounds for this vulnerability.\n\n### References\n\nPatch pull request: https://github.com/anchore/syft/pull/1538",
