Absolute path traversal vulnerability in curl 7.20.0 through 7.21.1, when the --remote-header-name or -J option is used, allows remote servers to create or overwrite arbitrary files by using \ (backslash) as a separator of path components within the Content-disposition HTTP header.

Security readout for executives and security teams

This older curl issue lets a malicious HTTP server influence where a downloaded file is saved, but only when curl is used with the remote-header filename option. The business risk is accidental file overwrite in legacy automation that fetches from untrusted or compromised servers. Exposure is most likely in legacy systems, scripts, CI jobs, appliances, or bundled tools using curl 7.20.0-7.21.1 with remote header filenames enabled. Treat as a targeted legacy cleanup item, not a broad emergency. Prioritize internet-facing automation, build systems, and privileged jobs that use old curl packages or trust server-provided filenames. Mitigation focus: Inventory curl versions on legacy hosts and embedded distributions.; Remove --remote-header-name or -J from untrusted download workflows.; Check curl and OS vendor guidance for the corrected package version..
