SECRETS_ENV_READ OBFUSCATION_FILE_OVER_READ_CAP

Why this grade

  • SECRETS_ENV_READ Note

    Reads an environment variable whose name contains KEY, SECRET, TOKEN, PASSWORD or CREDENTIAL.

    mongodb-lens.test.js, line 2333 disableTokens: process.env.CONFIG_DISABLE_DESTRUCTIVE_OPERATION_TOKENS === 'true'

  • OBFUSCATION_FILE_OVER_READ_CAP Note

    A file was over the read cap and was not fully read.

    mongodb-lens.js, line 1 #!/usr/bin/env node

Any High, or two or more Medium findings, give D. One Medium gives C. Low findings or a security Note give B. Each code names a finding behind the letter.

Grades are a hygiene check of the source at the commit shown, on the date checked, not a security audit or a guarantee. The free directory grades are automated. Before release, a PlugVet engineer reviews every paid report and any grade we hold back, including all F grades, against the source code and the evidence we quote.
