CVE-2025-14925
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedHugging Face Accelerate Deserialization of Untrusted Data Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Hugging Face Accelerate. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of checkpoints. The issue results from the lack of proper validation of user-supplied data, which can result in deserialization of untrusted data. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-27985.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceHugging Face Accelerate contains a deserialization vulnerability in its checkpoint parsing logic. The library fails to properly validate user-supplied data during checkpoint loading, allowing attackers to craft malicious checkpoint files that execute arbitrary code when opened by victims.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify if Accelerate is installedRun 'pip show accelerate' or 'pip list | grep -i accelerate' to check if the library is present in your environmentAffected if Accelerate is not installed, the vulnerability does not apply to your environment
-
Determine installed Accelerate versionRun 'pip show accelerate' and note the Version field, then compare it against the affected version range for this CVEAffected if The installed version falls within the vulnerable version range and you load checkpoint files
-
Check for checkpoint loading codeSearch your codebase for calls to 'from_pretrained', 'load_checkpoint', or similar Accelerate checkpoint loading functions using grep or IDE searchAffected if Your code loads checkpoint files using Accelerate functions, exposing you to the vulnerable code path
-
Audit checkpoint file sourcesReview your data pipelines and code to identify where checkpoint files originate (local storage, untrusted URLs, user uploads, shared repositories)Affected if You load checkpoints from untrusted or third-party sources without validation
-
Inspect custom checkpoint deserializationReview any custom implementation that parses Accelerate checkpoint files directly, looking for unpickling or unsafe deserialization of checkpoint dataAffected if Custom code performs unsafe deserialization on checkpoint data without validation
You are affected if Hugging Face Accelerate is installed at a vulnerable version AND your environment loads checkpoint files, particularly from untrusted or third-party sources.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUsers should avoid loading checkpoints from untrusted sources. The library maintainers should implement strict input validation and safe deserialization practices for checkpoint files.
