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 attacker may cause a denial of service by crafting an Accept-Language header which ParseAcceptLanguage will take significant time to parse.

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

The ParseAcceptLanguage function can be exploited via specially crafted Accept-Language HTTP headers that cause the parser to consume excessive CPU time, leading to denial of service.

MitigationImplement input validation, length limits, or parsing timeouts on Accept-Language headers; otherwise upgrade to a patched version if the library is identified.

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. Identify golang.org/x/text usage
    Search your codebase (go.mod, go.sum) for 'golang.org/x/text' dependency and note its version
    Affected if The installed version is lower than 0.3.8
  2. Locate ParseAcceptLanguage calls
    Search your codebase for imports of 'golang.org/x/text/language' and usages of 'ParseAcceptLanguage' function
    Affected if Code directly calls ParseAcceptLanguage to parse Accept-Language headers
  3. Check for input validation
    Inspect the code paths that handle Accept-Language HTTP headers; look for length limits, validation, or timeouts applied before calling ParseAcceptLanguage
    Affected if Accept-Language headers are passed to ParseAcceptLanguage without prior validation or limits

You are affected if your project uses golang.org/x/text version below 0.3.8 and processes unvalidated Accept-Language headers via ParseAcceptLanguage.

Generated from the published advisory. Verify against your own configuration.

Check your environment

Paste your version and any relevant configuration and it will be compared against the affected criteria above. Do not include secrets or credentials.

AI-assisted, checked against the advisory. Informational, not a guarantee.

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.

dbcve · scoped
Upgrade available Upgrade to 0.3.8 or later
Fixed in 0.3.8
Interim mitigation

Implement input validation, length limits, or parsing timeouts on Accept-Language headers; otherwise upgrade to a patched version if the library is identified.

Recommended fix High confidence

golang.org/x/text v0.3.8

  1. Identify all Go modules that depend on the 'golang.org/x/text' package by running 'go list -m all' or inspecting go.mod files
  2. Run 'go get golang.org/x/[email protected]' to upgrade the text package to the fixed version
  3. Run 'go mod tidy' to clean up dependencies and update go.mod/go.sum files
  4. Rebuild and redeploy the application to include the patched library
