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 · unedited
An exploitable use-after-free vulnerability exists in the account parsing component of the Ledger-CLI 3.1.1. A specially crafted ledger file can cause a use-after-free vulnerability resulting in arbitrary code execution. An attacker can convince a user to load a journal file to trigger this vulnerability.

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 confidence

A use-after-free vulnerability exists in the account parsing component of Ledger-CLI 3.1.1. When parsing a specially crafted ledger/journal file, the software frees memory used during account parsing but subsequently uses a dangling pointer to that freed memory region, leading to arbitrary code execution.

MitigationUsers should not open ledger files from untrusted or unverified sources. Upgrade to a patched version of Ledger-CLI when available from the vendor.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Verify Ledger-CLI is installed
    Run command: ledger --version or which ledger
    Affected if Ledger-CLI is not installed on the system, then not affected
  2. Identify the installed Ledger-CLI version
    Execute: ledger --version and capture the output
    Affected if Version shown is 3.1.1 exactly, then vulnerable version is present
  3. Confirm the binary is the official Ledger-CLI
    Check file metadata: ls -la $(which ledger) and verify package origin if managed by package manager
    Affected if Binary is Ledger-CLI version 3.1.1 from official distribution, then vulnerable
  4. Determine if ledger journal files are processed
    Review operational practices: check if users import or process .ledger or .journal files from external sources
    Affected if Ledger-CLI 3.1.1 is used to parse journal files (its normal function), then the attack surface exists

System is affected if Ledger-CLI version 3.1.1 is installed and is used to parse ledger/journal files, as the vulnerability triggers during account parsing of a crafted file.
